RECONFIGURABLE GENERATION OF QUANTUM OPTICAL FREQUENCY COMB
Abstract
Quantum optical frequency comb (QOFC) is a scalable quantum resource where quantum information is encoded at multiple frequency modes of light. While QOFC has been demonstrated both in the discrete-variable and the continuous-variable regimes, its generation process is typically uncontrollable, so that the resulting QOFC exhibits a limited form of quantum correlation, bipartite entanglement. In this project, we will study how to generate QOFC in a reconfigurable manner, which can produce various forms of quantum entanglement (e.g., multipartite entanglement) in multiple frequency modes. To achieve this goal, we will manipulate the frequency distribution of the ultrashort pump laser that is used for a multimode parametric down-conversion process. We will experimentally investigate how the pump laser affects the quantum correlations in the generated QOFC. This reconfigurable generation largely extends the capability of current QOFC, and it will have broad applications for quantum technologies requiring both flexibility and scalability, e.g., Gaussian Boson Sampling, distributed quantum sensing, and multi-player quantum communication.
