Joint measurement of time-frequency entanglement via sum frequency feedback

2019 · arXiv (Cornell University)

We propose, analyze and evaluate a technique for the joint measurement of time-frequency entanglement between two photons. In particular, we show that the frequency sum and time difference of two photons could be simultaneously measured …

Biphoton engineering using modal spatial overlap on-chip

2022 · Optics Letters

Photon pairs generated by spontaneous parametric downconversion are essential for optical quantum information processing, in which the quality of biphoton states is crucial for the performance. To engineer the biphoton wave function (BWF) on-chip, the …
