QUANTUM COMPUTATIONAL ADVANTAGE WITH A PROGRAMMABLE PHOTONIC PROCESSOR

JONATHAN LAVOIE, EXPERIMENTAL PHYSICIST XANADU QUANTUM TECHNOLOGIES

A quantum computer attains computational advantage when outperforming the best classical computers running the best-known algorithms on well-defined tasks. No photonic machine offering programmability over all its quantum gates has demonstrated quantum computational advantage: previous machines were largely restricted to static gate sequences. I will discuss a quantum computational advantage using Borealis, the latest of Xanadu’s photonic processors offering dynamic programmability and available on the cloud. This work is a critical milestone on the path to a practical quantum computer, validating key technological features of photonics as a platform for this goal.
