Robust generation and transfer of multiphoton states using reduced-symmetry quantum photonics

Abstract

This research proposal aims to design and implement non-Hermitian photonic platforms that enable efficient generation and robust processing of quantum information in multiphoton systems. By harnessing losses in photonic integrated circuits, the goal is to increase the channel capacity of quantum photonic devices and implement photon-mediated two-qubit quantum gates. The research team plans to leverage emergent topological features in reduced-symmetry non-Hermitian systems, including parity-time symmetry systems. The proposal builds upon the team s expertise in multiphoton quantum systems and utilizes experimental capabilities developed in the U.S. The research approach involves multiphoton interactions in waveguide networks realizing exceptional photonic lattices, with tasks focused on systematic identification of order-invariance properties, experimental implementation of multiphoton quantum state transfer, and dissipation-assisted multiphoton entanglement generation. The expected outcomes include the development of robust quantum photonic technologies and the advancement of on-chip quantum protocols for secure quantum communication and distributed quantum computing. The proposed research aligns with the goals of the U.S. Department of Defense on integrated nanophotonics, as highlighted in a recent Planning Strategy report by the Army Research Office.
