Quantum Computing at Room Temperature By 2030 | NextBigFuture.com

Transparent crystals with optical nonlinearities could enable quantum computing at room temperature by 2030. Army Researchers and Dr. Mikkel Heuck and Prof. Dirk Englund of the Massachusetts Institute of Technology have demonstrated the feasibility of a quantum logic gate comprised of photonic circuits and optical crystals. Researchers can engineer cavities in the crystals that temporarily trap photons inside. Through this method, the quantum system can establish two different possible states that a qubit can hold: a cavity with a photon (on) and a cavity without a photon (off). These qubits can then form quantum logic gates, which create the framework
