Classical State Detection Using Quantum State Tomography
Kim Fook Lee, Prem Kumar
We present a model to detect a classical state mixed with an idler photon from a polarization-entangled pair. A weak coherent light with a well-defined polarization, matched in wav…

Non-Markovian Dynamics in Fiber Delay-line Buffers
Kim Fook Lee, Prem Kumar
We study the non-Markovian effect on a two-photon polarization entangled state, in which one photon from the pair is stored in a fiber delay-line buffer. We propose a model of a ph…

Hong-Ou-Mandel Interference with a Coexisting Clock using Transceivers for Synchronization over Deployed Fiber
Anirudh Ramesh, Daniel R. Reilly, Kim Fook Lee +8
Interference between independently generated photons is a key step towards distributing entanglement over long distances, but it requires synchronization between the distantly-loca…
