Improving the loss threshold for quantum advantage in photonic sensors by complete photon counting
Gerard J. Machado, Yazeed K. Alwehaibi, Guillaume Thekkadath +9
Tolerance to imperfections is a defining performance criterion for quantum sensors. The threshold for achieving a quantum advantage depends on the input state, sensor configuration…
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…
Quantum Position Verification with Remote Untrusted Devices
Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +17
Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…
Sub-femtosecond stabilization of multicore fiber for high-fidelity quantum networking at 100% duty cycle
Takuma Nakamura, Nazanin Hoghooghi, Nicolas Fontaine +8
Originally envisioned as a solution for the capacity crunch in telecommunications networks, multicore fibers (MCF) are contributing to scientific fields beyond telecom, such as sen…
