GPS hacking and spoofing have made headlines around the world in recent years, from researchers successfully hacking a yacht’s navigation to bring it off its programmed course to the discovery of dozens of Russian ships whose GPS signals indicated they were on land when they were in fact out on …

Quantum key distribution (QKD), establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that any attempts to intercept and measure quantum transmissions, will introduce an anomalously high error rate …

U.S. military researchers are asking industry to develop relatively simple portable photonic integrated circuits (PICs) for high-performance position, navigation, and timing (PNT) devices as an alternative to the Global Positioning System (GPS) for when GPS signals are not available.   Position, Navigation, and Timing (PNT) is a critical resource for …

Quantum computing and quantum information processing are next revolutionary technology expected to have immense impact. Quantum information technologies, such as quantum computers, cryptography, radars, clocks, and other quantum systems, rely on the properties of quantum mechanics, which describes the behavior of matter at the subatomic scale. For example, by taking advantage …

The extraordinary promise of quantum technology—depend on quantum “entanglement,” in which the physical states of two or more objects such as atoms, photons or ions become so inextricably connected that the state of one particle can instantly influence the state of the other—no matter how far apart they are. Today, …

In recent years there has been a major scientific thrust to harness quantum phenomena to increase the performance of a wide variety of classical devices ranging from computation to sensing, and considerable progress has occurred in the analysis and design of photonic-based quantum sensors (e.g. quantum radar and quantum lidar). …

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. Quantum sensors are measuring device that takes advantage of quantum correlations, such as states in a quantum …

The emerging quantum revolution offer revolutionary capabilities for military from quantum creptography for hack proof communications to High-precision atomic clocks that can enable timekeeping for navigation and communications with GPS-like performance even in GPS-denied environments. Another important area is quantum  computing based on quantum bits, or qubits, which can represent …

Quantum walks are the quantum version of classical random walks, which are a mathematical means for describing a natural random walk, e.g., simply wandering around randomly.   In a “classical random walk”, you could imagine someone starting at the centre of a city, and making a random decision at each …

China is developing a new type of spy satellite using ghost imaging technology which could spot stealth aircraft and see through smokescreens and camouflage.   Ron Meyers, quantum physicist at the Army Research Laboratory. Meyers explained ghost imaging, a technique that allows a high resolution camera to produce an image …
