Novel error-correction scheme developed for quantum computers

Science Daily  March 11, 2020
Bosonic rotation codes are based on phase-space rotation symmetry. Researchers in Australia present a universal quantum computing scheme applicable to a subset of this class which includes the well-known cat and binomial codes, among many others. The entangling gate in the scheme code can be used to interface different rotation-symmetric encodings. They propose a teleportation-based error-correction scheme that allows recoveries to be tracked entirely in software. Numerically have shown that the error-correction scheme is close to optimal for error-free ancillae and ideal measurements and present a scheme for fault-tolerant, universal quantum computing based on the concatenation of number-phase codes and Bacon-Shor subsystem codes…read more.
