We are in midst of the second quantum revolution moving from merely computing quantum properties of systems to exploiting them. Researchers are developing new capabilities in secure communication, ultra-sensitive and high signal to noise physical sensing of the environment and Quantum Information Science (QIS). Yet many scientists believe that quantum will enjoy its first real commercial success in sensing. That’s because sensing can take advantage of the very characteristic that makes building a quantum computer so difficult: the extraordinary sensitivity of quantum states to the environment.
Quantum sensors are measuring device that takes advantage of quantum correlations, such as states in a quantum superposition or entanglement, for better sensitivity and resolution than can be obtained by classical systems. A quantum sensor can measure the effect of the quantum state of another system on itself. The mere act of measurement influences the quantum state and alters the probability and uncertainty associated with its state during measurement. For decades, quantum measurements have been used in metrology to define fundamental constants such as time. More recently, this approach is being applied to sensing.
When measurements are based on quantum phenomena, such as the energy difference between two well-defined quantum states, sensors have the ability to reach unprecedented precision and accuracy that doesn’t drift over time. High sensitivity and stability in combination with a small form factor provide transformational capabilities with applications spanning from GPS-free global navigation and cryogen-free high-precision magnetometry to sensing within mesoscale structure and measurements of individual nuclear or electron spins.

Quantum sensors include atomic clocks, single-photon detectors, PAR sensors, quantum LiDAR and quantum radar, gravity sensors, atomic interferometers, magnetometers, quantum imaging devices, spin-qubit-based sensors, and quantum rotation sensors. We also take a look at materials used for quantum sensors, especially diamond and graphene
Quantum sensors also useful in many military applications such as through wall imaging, detecting deeply buried structures and stealth airplanes. In particular, quantum radar can be used to detect targets that cannot be discerned through conventional radar, and quantum navigation similarly leverages quantum properties to create a precise form of positioning system that may eventually replace GPS.
Whether they are responding to the gravitational pull of buried objects or picking up magnetic fields from the human brain, quantum sensors can detect a wide range of tiny signals from the world around us. Kai Bongs, a physicist at Birmingham University, U.K., believes that gravity-measuring quantum sensors in particular “will become more widespread quite quickly,” with a potential market of perhaps US$1 billion a year.
Quantum Sensor technology
Quantum sensing has become a distinct and rapidly growing branch of research within the area of quantum science and technology, with the most common platforms being spin qubits, trapped ions and flux qubits.
For over 30 years, academics have been exploring the strange effects of quantum superposition – the principle that 2 or more quantum states can be added together to result in another valid quantum state – to measure gravity. This is done by comparing wave-particle duality – the concept that quantum entities can be described both as particles and waves – in atoms of the element rubidium. By comparing wave-particle duality with a laser beam, the instrument will be able to detect very small changes in the way atoms fall freely in a vacuum, determining the local strength of gravity. If the measurement is sensitive enough, it will be able to detect if there are voids, pipes, tunnels and oil and gas reserves in the ground beneath your feet.
Atom interferometers could also be used to build navigation devices that continue to work even when contact with GPS satellites is lost, as can happen in a tunnel or, more ominously, when signals are deliberately jammed. Keeping on course in this way relies on dead reckoning, the use of accelerometers and gyroscopes to continuously update a vehicle’s position, orientation and velocity with respect to a known starting point.
Like spring gravimeters, conventional accelerometers experience drift, as their pendula warp over time. In contrast, quantum accelerometers—essentially gravimeters with their laser beams flipped along the acceleration axis—are very stable. Although the atoms’ finite free-fall time and need for preparation prevent continuous operation, which is often provided by conventional accelerometers, they enable proper calibration.
Quantum gyroscopes, meanwhile, work by generating a phase difference between atom waves propagating in opposite directions around a rotating ring. Such technology has been developed by AOSense, a company in Sunnyvale, Calif., USA, set up in 2004 by atomic physicist Mark Kasevich and two colleagues at Stanford University, USA. Often working with the U.S. military, the firm built prototype gradiometers, gyroscopes and accelerometers for the Defense Advanced Research Projects Agency (DARPA). The aim, according to a 2014 story in Physics Today, was to make inertial measurement units that could fit on a fingertip. But in the end, Kasevich says, the necessary lasers and optical modulators couldn’t be made small enough to shrink gyroscopes below “about 100 cm3.”
Making atomic sensors competitive with existing technology is “a struggle,” according to Kasevich, because the subsystems that they rely on, such as lasers and vacuum chambers, are large and complex, and have not had their costs driven down by mass markets. Trying to shrink gyroscopes in particular incurs “crazy development costs,” says Pereira Dos Santos. One option would be to guide rather than drop atoms, but that, he says, is “very exploratory … and it might never work.”
But another type of quantum technology has simple subsystems and can be built using standard materials-science techniques: nitrogen–vacancy (NV) centers. These are atom-like defects in a synthetic diamond crystal consisting of a nitrogen atom and a gap in place of two carbon atoms. NV centers can emit red light when excited by green, but the probability of doing so depends on the spin states of their electrons. By placing the spin states in a superposition, microwaves with just the right frequency can change the emission intensity.
Crucially, this quantum state can persist for up to a millisecond at room temperature, thanks to the stiff diamond lattice that shields the NV centers from vibrations. And, because changes in the local magnetic field will change the spacing of the spin states and knock the microwave frequency off-resonance—with the change proportional to the field strength—NV centers could potentially make extremely sensitive magnetometers. The system is also sensitive to variations in electric field, strain and temperature, as these change the distance between atoms and, again, shift the resonance.
Commercialization of Quantum Sensors
Quantum sensors are just becoming commercially available. Numerous scientists working on quantum sensors have set up companies to commercialize their technology, but few have actual products on the market.
Several start-up companies are looking to commercialize NV technology, in areas such as biomedicine, while some multinationals are also entering the fray. These include the German engineering giant Bosch, which is building a prototype NV sensor to monitor charging and prevent excess currents in car batteries. The French electronics company Thales, meanwhile, is applying magnetic field gradients across NV diamond crystals to identify frequency components in unknown microwave spectra.
According to Thales’ head of applied quantum physics, Thierry Debuisschert, 5G network operators could use this technology, for example, to prevent interference between neighboring cell towers. But he says that it will likely take several years to overcome technical and commercial obstacles, such as working out how best to collect the faint red light emitted by the crystal. Likewise, Bosch researcher Robert Roelver says that his company probably won’t market a device for another five to ten years.

For instance, a research study conducted by the University of Bristol revealed the discovery of a new method that could be employed to build quantum sensors with ultra-high precision. A conducted research said that such quantum sensors were able to avoid the presence of vibrations due to solid materials that are, in fact, much larger objects and are usually considered to be detrimental.

There is a high level of preliminary investment required in end-user industries for integrating such sensors in packages, along with self-sufficient riding or autonomous driving, advanced imaging technologies both at short and lengthy distances, clinical progress, and permitting the distinct mapping of the underground. The excessive expenses of putting in place these structures are concerned with proper setup, design, and fabrication. Also, the operational and maintenance cost of those sensors is on a piece higher aspect.
The gathering of accumulated dust and different soluble deposits on these sensors requires everyday cleaning, simplest by means of water and/or a slight detergent, which include dish-washing soap and vinegar for maintenance. Such cleaning exercise is quite essential to ensure the accuracy of the calibration. Regular protection is needed to avoid negative outcomes at the cosine reaction of the sensor for the reason that acrylic fabric utilized in some of the quantum sensors may be crazed with exposure to alcohol or natural solvents.
However, challenges such as quantum decoherence, the inconsistency between separating the responsive quantum states from external conflicts, and reliance on only some key providers are major restraining factors that could hamper the growth of the market.

For instance, in October 2018, the US Army scientists created innovative quantum sensors to detect the communication signals over the radio frequency spectrum. This quantum sensor uses high energized, super-sensitive atoms named as Rydberg atoms. This quantum sensor provides military soldiers an approach to sense communication signals over the wide spectral coverage range from 0 to 100 GHz.
