Two-Cavity System Generates High-Quality Single Photons Efficiently

A new dual-cavity design for a quantum emitter, from the Massachusetts Institute of Technology (MIT), emits more high-quality single photons for carrying quantum information at room temperature than existing methods. The two-cavity system could make the development of quantum computers more practical. MIT researchers have designed a new single-photon emitter that generates, at room temperature, more of the high-quality photons that could be useful for practical quantum computers, quantum communications, and other quantum devices.  While classical computers process and store information in bits of either 0s or 1s, quantum bits (qubits) can be 0 and 1 simultaneously.  To create qubits, it is necessary to produce single photons with identical quantum properties, known as “indistinguishable” photons… READ MORE
