In-Situ Measurement of Beam Divergence in a High Efficiency SNSPD Platform
Daniel W. Sorensen, Martin J. Stevens, Lynden K. Shalm +1
We implement a time-of-flight imaging technique utilizing a differential-readout SNSPD to spatially resolve detection events in a fiber-coupled detector platform. We measure the sp…

High-performance source of indistinguishable polarization-entangled photons with a local oscillator reference for quantum networking
Michael Grayson, Shawn Meyer, Daniel Sorensen +9
Optical quantum networking protocols impose stringent requirements on the states produced by sources of entanglement. We demonstrate a free-space, compact, source of indistinguisha…

Phase-Stable Optical Fiber Links for Quantum Network Protocols
Nicholas V. Nardelli, Dileep V. Reddy, Michael Grayson +5
We demonstrate the distribution of single-photon-level pulses from a mode-locked laser source over a phase-stable fiber link, achieving an optical timing jitter of less than 100 as…
