Quantum entanglement is a physical phenomenon where two particles remain inter-connected, sharing physical traits regardless of how far apart they are from one another. Scientists from the Institute of Science and Technology Austria (IST Austria) — along with collaborators from the Massachusetts Institute of Technology (MIT), the University of York (UK), and the University of Camerino, Italy — have demonstrated a new type of detection technology called “microwave quantum illumination” that utilizes entangled microwave photons as a method of detection. The prototype, also known as a “quantum radar,” is able to detect objects in noisy thermal environments where classical radar systems often fail.
