Quantum photonic technologies set to be more reliable with new interferometer. - EurekAlert
An increasing number of emerging quantum applications operate using optical technologies. Currently, quantum photon sources are regularly taken offline to be tested and adjusted using an interferometer. This requires comparing photons multiple times using different configurations, a process that is time consuming and requires relatively bulky equipment. Researchers at TMOS have designed and demonstrated a new device that uses an ultra-thin metasurface to do all the necessary measurements in a single pass.
