Local Versus Global Two-Photon Interference in Quantum Networks

2020 · Physical Review Letters

We devise an approach to characterizing the intricate interplay between classical and quantum interference of two-photon states in a network, which comprises multiple time-bin modes. By controlling the phases of delocalized single photons, we manipulate …

Two-Rebit Entanglement: Theory and Experiment

2021 · Quantum Information and Measurement VI 2021

We characterize entanglement over real and complex, composite quantum systems. Methods are formulated and applied to simultaneously certify inseparability and separability for two rebits and two qubits, respectively.
