Researchers at the UK Quantum Technology Hub Sensors and Timing, led by the University of Birmingham, have designed and implemented an approach for miniaturizing devices used in quantum sensing systems. A new technique for shrinking the size of quantum sensors drives the discovery, which relies on optical metasurfaces cutting the amount of space a laser delivery system needs to achieve functionality in quantum technology.
Sensing-device quantum technology works by controlling laser beams to engineer and manipulate atoms at supercold temperatures. This typically necessitates a vacuum chamber holding atoms for cooling. In this setup, a laser fires photons at the atoms while they are in motion, lowering their momentum and cooling them….READ MORE
