 講演概要:
Integrated quantum photonics holds the promises to scale up the number of quantum nodes in a system and to build a network with distributed quantum information processing units at affordable resources. An outstanding need and the grand challenge of such systems is to have near-unity success rate of state transfer between the quantum nodes on the chip. Here we propose a type of composite quantum node consisting of a matter-based quantum system and a photonic structure, i.e., a coupled cavity cluster, for achieving perfect state between two nodes connected with a waveguide. The composite node possesses extra degrees of freedom in controlling the temporal profile of the emission from the matter system and can generate time-reversal symmetric single-photon wave packets without any dynamic modulation. By taking a cavity cluster consisting of three chain-coupled microring resonators as an example, we demonstrate in principle that state transfer between two composite nodes on the chip with the success rate around 99% is achievable. We develop a general theoretical framework and give a clear physical picture of the protocol. Moreover, we discuss the influence of imperfections and experimental implementation of our scheme with integrated photonics and solid-state quantum optics techniques.
