Quantum secret sharing with polarization-entangled photon pairs

2019 · Physical Review A

We describe and experimentally demonstrate a more practical three-party quantum secret sharing (QSS) protocol using polarization-entangled photon pairs. The source itself serves as an active participant and can switch between the required photon states by …

A Reconfigurable Quantum Local Area Network Over Deployed Fiber

2021 · Conference on Lasers and Electro-Optics

We demonstrate a three-node telecom quantum local area network over deployed fiber. It has eight independent entanglement channels which are dynamically reconfigurable. We successfully show entanglement demand balancing across the network and quantify its quality.

A two-qudit operation on a 256-dimensional Hilbert space

2019 · Conference on Lasers and Electro-Optics

By encoding two 16-dimensional qudits in the time and frequency degrees of freedom of a heralded single photon, we realize a deterministic photonic two-qudit SUM gate operating on a 256-dimensional Hilbert space.
