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…
Detection-loophole-free nonlocality in the simplest scenario
Nandana T Raveendranath, Travis J. Baker, Emanuele Polino +7
Loophole-free quantum nonlocality often demands experiments with high complexity (defined by all parties' settings and outcomes) and multiple efficient detectors. Here, we identify…
Quantum Position Verification with Remote Untrusted Devices
Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +16
Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…
A heralded quantum amplifier of multi-photon states
Luis Villegas-Aguilar, Farzad Ghafari, Matthew S. Winnel +5
Large-scale quantum networking systems will inevitably require methods to overcome photon loss. While the no-cloning theorem forbids perfect and deterministic amplification of unkn…
Entanglement distillation rates exceeding the direct transmission bound
Farzad Ghafari, Josephine Dias, L Krister Shalm +4
Entanglement distribution is crucial for quantum communication and cryptography but is hindered by channel loss and decoherence. Noiseless linear amplification (NLA) is a probabili…
