Mode expansion and Bragg filtering enable a high-fidelity fiber-based photon-pair source
Alexander Ling, Jun Chen, Jingyun Fan +1
We report the development of a fiber-based single spatial mode source of photon-pairs where the efficiency of extracting photon-pairs is improved over a previous source [18] throug…
Resolution and sensitivity of a Fabry-Perot interferometer with a photon-number-resolving detector
Christoph F. Wildfeuer, Aaron J. Pearlman, Jun Chen +3
With photon-number resolving detectors, we show compression of interference fringes with increasing photon numbers for a Fabry-Perot interferometer. This feature provides a higher…
Demonstration of a Quantum Controlled-NOT Gate in the Telecom Band
Jun Chen, Joseph B. Altepeter, Milja Medic +5
We present the first quantum controlled-NOT (CNOT) gate realized using a fiber-based indistinguishable photon-pair source in the 1.55 m telecommunications band. Using this free-…
Quantum theory of degenerate two-photon state
Jun Chen, Kim Fook Lee, Prem Kumar
We developed a quantum theory for degenerate two-photon state generated from optical fiber, and compared the theory predictions with an experimental result which exhibits…
An integrable optical-fiber source of polarization entangled photon-pairs in the telecom band
Xiaoying Li, Chuang Liang, Kim Fook Lee +3
We demonstrate an optical-fiber based source of polarization entangled photon-pairs with improved quality and efficiency, which has been integrated with off-the-shelf telecom compo…
