Ultra-Dense Quantum Communication Using Integrated Photonic Architecture

Abstract

We report on the theoretical and experimental progress on photonefficient quantum key distribution. We have derived theoretical bounds on the upper bound on the private capacity and developed a novel large-alphabet quantum key distribution protocol employing security through measurements in mutually unbiased bases. In experimental efforts, we advanced the photonic integrated chip architecture, including linear optics for security checks and chipintegrated high-performance single photon detectors.
