Quantum Computer Platform Uses Optical Fiber to Perform at Room Temperature

A team at the Technical University of Denmark (DTU) has developed what it calls a “complete platform” for an optical quantum computer. The platform is universal and scalable, the team said, and takes place at room temperature. The technology is compatible with standard fiber optic networks. The demonstration of a so-called universal gate set — and the implementation of several operations by means thereof — is what the team said constitutes an optical quantum computing advancement. Gates serve to perform operations on one or more qubits, and to implement an algorithm given that qubits are carriers of information. “Our demonstration of a universal set of gates is absolutely crucial. It means that any...
