Quantum Information Science with Reconfigurable Photonic Waveguide Array

ORAL

Abstract

Photonic waveguide array has been used in a number of applications ranging from demonstrating condensed matter physics and processing classical and quantum

information. However, those devices lack reconfigurability or precise control of the device Hamiltonian. In this study, we present a Reconfigurable Waveguide Array (RWA) with 11 waveguides based on Lithium Niobate and experimentally demonstrate various applications including programming Hamiltonians, tunable quantum interference, and multi-dimensional quantum logics. These results open up new avenues for exploring the potential of this technology in photonic quantum computing.
