We perceive the world because our eyes are sophisticated light detectors. They constantly capture light rays reflecting off nearby objects, enabling our brains to construct a dynamic image of our surroundings. Photography—our attempt to freeze these light impressions—has revolutionized how we record, remember, and relate to the world. Yet, no matter how vivid or artistic a photograph may be, it remains a static snapshot of a fleeting moment. The light captured in the image has long since vanished, never to return.
Holography, by contrast, offers a different promise. Holograms are like photographs that preserve more than just a flat image—they maintain depth and perspective. When you view a high-quality hologram from different angles, it reveals new details, allowing you to see the object as though it were still present and moving in space.
Beyond Photography: Capturing the Phase of Light
Photography captures the intensity of light—how much light of each color hits the sensor or film. But light is also a wave, characterized not only by intensity but also by phase. Phase determines a wave’s position within its cycle and encodes depth information, which is lost in traditional photography. Optical holography leverages this phase information, allowing for the reconstruction of a full 3D image of the object.
In standard photography, individual points of an image register light intensity only. In classical holography, the interference phenomenon also registers the phase of the light waves (it is the phase which carries information about the depth of the image).
When a hologram is created, a well-described, undisturbed light wave (reference wave) is superimposed with another wave of the same wavelength but reflected from a three-dimensional object (the peaks and troughs of the two waves are shifted to varying degrees at different points of the image). This results in interference and the phase differences between the two waves create a complex pattern of lines.
A hologram records the interference pattern formed when a reference beam of light intersects with light scattered from an object. When the hologram is illuminated with the original reference beam, the light diffracts in such a way that it recreates the object’s original wavefronts. The result is a 3D image that appears lifelike and can change perspective with the viewer’s movement.
Thanks to the invention of lasers—intense, coherent light sources—optical holography has become a widely used technique in imaging, security (e.g., anti-counterfeit labels), microscopy, and data storage.
Quantum Holography: The Next Frontier
At the cutting edge of holography lies quantum holography, a field that leverages the strange properties of quantum entanglement. Entanglement links particles so that the state of one instantly influences the state of another—no matter the distance. This phenomenon allows quantum holography to record not just intensity and phase, but also quantum information encoded in photons.
Quantum holography makes use of entangled-photon pairs, one of which one scatters from the remote object while the other is locally manipulated using conventional optics that offers full spatial resolution. Remarkably, the underlying entanglement permits the measurement to yield coherent holographic information about the remote object. Quantum entanglement enables information processing with capabilities beyond technology based on classical principles.
Through this “non-local” interaction, structural properties such as refractive index or thickness are encoded into the quantum state of light, enabling holograms to be reconstructed even when traditional coherence conditions aren’t met. This principle not only opens doors to ultra-sensitive biological imaging but also offers a new layer of security in optical communication systems.
Entangled Photons and the Birth of Quantum Holograms
In 2016, physicists at the University of Warsaw made a breakthrough by creating the first-ever hologram of a single photon. Using a novel quantum interference technique, they overcame what was long thought to be an insurmountable barrier: capturing the wavefront of a single light particle. The experiment, led by Dr. Radoslaw Chrapkiewicz and Michal Jachura under the guidance of Dr. Wojciech Wasilewski and Prof. Konrad Banaszek, was published in Nature Photonics.
From Classical to Quantum Interference: A New Path to Holography
It might seem intuitive to assume that holographic interference could be replicated with just a single reference photon and a single photon reflected from an object, mimicking classical wave interference. However, this assumption falls apart in the quantum realm. Unlike classical light waves, individual photons exhibit phase fluctuations that prevent traditional interference patterns from forming. Faced with this challenge, physicists at the University of Warsaw explored a novel solution: rather than relying on classical electromagnetic wave interference, they sought to harness quantum interference—specifically the interaction of photon wave functions. This approach marked a fundamental shift from conventional optics to quantum mechanics as a medium for holographic imaging . This method allowed them to reconstruct both the amplitude and the phase of the photon’s wavefunction, an essential parameter in quantum mechanics.
At the core of this breakthrough lies the wave function, a central concept in quantum mechanics encapsulated by the Schrödinger equation. Much like clay in a sculptor’s hands, a well-defined wave function allows physicists to model the probabilistic nature of particles. The square of a wave function’s modulus represents the likelihood of a particle being found in a specific state—a principle crucial for understanding quantum behavior. In the Warsaw experiment, instead of analyzing light intensity, the team studied the probability distributions resulting from photon pairs undergoing quantum interference. As doctoral student Radosław Jachura noted, this method offered a simpler yet profoundly insightful route to exploring the elusive phase of a photon’s wave function.
The team started with pairs of photons with known wavefronts and polarizations. Using a cylindrical lens, they manipulated the wavefront of one photon, creating an “unknown” state. The two photons then interfered at a beam splitter, and the resulting pattern was captured using a specialized camera. These photons were then directed toward a calcite beam splitter after polarization adjustment, and their interactions were recorded by a custom-built high-resolution camera.
By analyzing repeated measurements, they constructed a hologram of the unknown photon, effectively revealing its 3D quantum shape. This experiment not only deepens our understanding of wavefunctions—fundamental yet elusive constructs in quantum theory—but also opens the door to applying quantum holography to more complex systems, such as atoms or molecules.
Metasurfaces: Miniaturizing Quantum Holography
Recent advancements leverage metasurfaces—nanoscale-engineered materials—to generate quantum holograms with entangled photons. Teams at the University of Exeter and Hong Kong University demonstrated holographic letters (“H,” “V,” “D,” “A”) whose visibility depends on photon polarization. By manipulating metasurface nanostructures, they achieved compact, high-resolution holograms critical for anti-counterfeiting and quantum communication
Breaking the Heisenberg Limit
One major limitation in traditional holography is its spatial resolution, typically bounded by the wavelength of light (~1 μm). This becomes inadequate at the nanoscale, where quantum devices and nanostructures reside.
In 2019, researchers at EPFL, led by Fabrizio Carbone, developed a groundbreaking method using free electrons in an ultrafast electron microscope to overcome this barrier. Instead of using traditional light beams, they employed quantum interactions between electrons and light, separating reference and imaging beams by energy rather than space. This allowed them to encode and decode quantum information in attosecond (10⁻¹⁸ seconds) timeframes and nanometer spatial scales.
This electron-based quantum holography not only provides ultrafine imaging of electromagnetic fields but also opens a path toward quantum information processing using free electrons—a radical step forward for quantum computing.
Quantum microscopy by coincidence (QMC) now achieves super-resolution imaging at the Heisenberg limit. By balancing optical paths of entangled photons, QMC doubles resolution while resisting stray light 155× better than classical methods. This enables imaging cancer cells at 1.4 μm resolution, merging quantum precision with biological relevance
Breakthrough Applications: Medicine, Security, and Anti-Counterfeiting
Quantum holography is already finding its way into transformative applications across industries. In biomedical imaging, it significantly outperforms classical microscopy in terms of noise resilience and resolution. It has been used to detect malaria parasites in red blood cells, observe real-time sperm cell behavior for in-vitro fertilization, and analyze tissues without staining or invasive contact. In the realm of quantum communication, entangled holograms support quantum key distribution (QKD), where attempts to intercept the hologram collapse its quantum state—providing immediate detection of eavesdropping.
Meanwhile, anti-counterfeiting technologies are set to undergo a quantum leap. Embedding metasurface-based quantum holograms in credit cards or passports creates a formidable dual-layer defense: replicating the intricate nanostructures is already challenging, but mimicking the entanglement-based encryption makes forgery virtually impossible.
Military Applications: Training with Holographic Reality
Holography is also transforming military training and simulation. Realistic holograms can provide cost-effective, immersive training environments for warfighters. The U.S. military has increasingly incorporated virtual humans and environments into combat preparation. The Institute for Creative Technologies (ICT) at the University of Southern California has developed virtual characters to assist soldiers before, during, and after deployment.
Dr. John Parmentola of the U.S. Army’s science and technology office is at the forefront of efforts to make “science fiction into reality” by developing photorealistic virtual humans—avatars that think, emote, and even speak in local dialects. These innovations are moving us closer to the “holodeck” concept popularized by Star Trek.
Holographic Metaverse
Meanwhile, the vision of a holographic metaverse is rapidly taking shape, driven by the convergence of 6G communication technologies, artificial intelligence, and quantum holography. This immersive 3D digital realm aims to allow users to interact through highly realistic, dynamic avatars—ushering in a new era of virtual presence and collaboration. Companies like WIMI Holographic Academy are at the forefront of this transformation, researching quantum-holographic computing and photon-based cloud architectures. Their goal is to miniaturize light manipulation techniques and integrate them into advanced photonic circuits, laying the foundation for seamless, high-fidelity holographic experiences embedded in everyday devices.
Peering into Spacetime: The Holographic Principle in Practice
Beyond practical uses, quantum holography touches on some of the deepest mysteries in theoretical physics. The holographic principle, proposed by physicist Juan Maldacena, suggests that our three-dimensional universe may be a projection of quantum information encoded on a two-dimensional surface—a radical idea that could reconcile general relativity with quantum mechanics. Recent advances using tensor networks and operator algebras have begun to mathematically model how the geometry of spacetime might emerge from patterns of quantum entanglement. Interestingly, experiments in quantum holography—such as imaging objects using undetected mid-infrared photons—offer real-world analogues to these theories, making them more than just abstract speculation. In essence, the very act of reconstructing quantum holograms mirrors the process by which spacetime might itself be “reconstructed” from quantum information.
Challenges and Future Horizons
Despite its promise, quantum holography faces several formidable challenges. Timing is one of the most critical: entangled photons must be synchronized with picosecond-level precision, as even nanosecond delays can distort or destroy the image. Scalability is another hurdle; current systems are largely confined to laboratory environments. However, the rapid progress in metasurface fabrication and integration suggests that compact, portable quantum holographic devices could become viable within the next decade. Theoretical questions also remain—chief among them, how much information can a quantum hologram truly encode? Scientists are exploring the possibility of building high-capacity “quantum highways” where holographic patterns carry vast streams of encrypted data through space.
The establishment of the WIMI Holographic Academy underscores a strategic shift toward interdisciplinary innovation. By consolidating research in AI, quantum physics, and photonics, the academy aims to advance holographic computing and communication sciences while addressing scalability challenges in micro-integration and cloud systems

At the frontier of this revolution is biological holographic computing, which integrates artificial intelligence with neural networks to mimic the brain’s architecture. This innovation allows real-time simulation and analysis of complex biological phenomena such as protein folding and cellular dynamics, potentially accelerating drug discovery and personalized medicine.
Meanwhile, quantum holographic computing exploits entangled photons to enable parallel processing capabilities. A notable demonstration by the University of Warsaw involved reconstructing single-photon wave functions—laying the foundation for powerful quantum computations with applications in cryptography, optimization, and artificial intelligence.
Complementing these advancements, photon holographic computing uses ultra-efficient light-based circuits to process and manipulate holographic data. These systems minimize energy loss and are essential for applications requiring real-time 3D rendering, such as augmented and virtual reality (AR/VR). Neutrino holographic computing, still largely theoretical, envisions harnessing the near-undetectable neutrino for ultra-secure communication across vast distances. In parallel, maglev holographic computing uses magnetic levitation to stabilize photonic systems, reducing thermal noise and enabling ultra-precise quantum operations.
All these pathways converge at institutions like the WIMI Holographic Academy, which is driving research to blend quantum mechanics with practical, AI-powered solutions in photonic and neural computing systems.
2. Holographic Communication Science: Redefining Connectivity
The integration of holography into advanced communication networks is redefining the very nature of human interaction and data transfer. Quantum holographic communication leverages entangled photons to transmit 3D visual and spatial data with extreme security and near-zero latency. This is being realized through Ericsson’s 5G holographic pipelines, which dramatically reduce communication delays, laying the groundwork for real-time, immersive interaction.
Photon holographic communication is already proving its viability. Companies like MATSUKO, in partnership with Verizon, have demonstrated real-time transatlantic holographic meetings, where users interact through high-fidelity 3D projections. This capability signals a leap forward in remote collaboration, particularly in business, telemedicine, and education.
Cutting-edge initiatives also explore brain-machine holographic communication, which combines AR with neural interfaces. This allows users to control holograms through thought—an ambitious focus area for WIMI’s AI-integrated platforms. Looking further ahead, quark and dark matter holographic communication remain speculative but fascinating, proposing the use of subatomic or cosmic particles to transmit information across interstellar distances. Meanwhile, maglev communication investigates using magnetic fields to guide photonic signals, aiming to overcome physical bandwidth constraints.
Together, these innovations are positioning holography as the technological backbone of future telepresence, immersive networking, and secure communication.
3. Micro-Integration Science: Miniaturizing the Future
Micro-integration science is concerned with embedding complex holographic functions into nanoscale and even atomic-scale devices—bringing immersive technologies into everyday objects. Photonic micro-integration involves integrating metasurfaces with 5G systems to produce ultra-compact holographic displays. WIMI’s development of light-field cinema systems exemplifies how these technologies are being commercialized for entertainment and information delivery.
Quantum micro-integration embeds qubits directly into device substrates, paving the way for ultra-secure holographic sensors and processors. Meanwhile, biological micro-integration links holographic systems with organic matter, enabling applications like AI-powered surgical guidance tools that segment tissues with millimeter precision—an innovation showcased by Tec de Monterrey.
In the energy domain, fusion and fission micro-integration aims to manipulate atomic bonds for long-term holographic data storage with minimal energy usage. Complementing this, neutrino micro-integration holds potential for environmental sensing and deep-earth scanning due to the neutrino’s penetrative power. These integrated systems could support applications ranging from planetary exploration to climate monitoring, and align with a broader global trend of distributed, highly specialized innovation clusters.
4. Holographic Cloud Science: Scaling Immersive Realities
To support the massive data loads and real-time demands of holographic systems, holographic cloud science is creating decentralized infrastructures that scale immersive computing across the globe. Quantum holographic clouds, powered by quantum encryption and computation, allow 3D data to be processed securely across distributed quantum servers. WIMI’s proposed 5G holographic platforms exemplify this approach, combining high-speed connectivity with encrypted cloud rendering.
Photon holographic clouds leverage edge computing to handle bandwidth-intensive light-field data, enabling responsive holographic interactions across mobile and wearable devices. This is particularly vital for emerging fields like holographic social media, where users demand high-quality, low-latency experiences.
Further innovations include atmospheric holographic clouds, which integrate environmental sensors to generate real-time holographic weather maps and pollution models. At an even larger scale, space holographic clouds envision networks of interconnected satellites enabling planetary-scale AR navigation and global remote sensing.
These systems rely heavily on AI-driven data fusion and the high throughput of 5G and future 6G networks. WIMI’s modeling algorithms, capable of processing over 10GB of holographic data per second, exemplify the computing intensity and innovation required to make truly global, immersive experiences possible
Conclusion: A Quantum Lens on Reality
Quantum holography is no longer just the stuff of futuristic fantasy—it is rapidly evolving into a robust toolset for reshaping how we see, measure, and secure the world. From capturing quantum fingerprints of biological cells to encoding unhackable messages and challenging our very concept of dimensional reality, quantum holography stands at the nexus of physics, engineering, and philosophy. As Jensen Li aptly puts it, “The beauty of quantum holography is that as we increase complexity, we strengthen both security and understanding.”
In the years to come, we may look back at this moment as the beginning of a new visual era—one where photons no longer just illuminate objects, but the very architecture of the universe itself.
