Doppler Shift Mitigation in a Chip-Scale Atomic Beam Clock
Alexander Staron, Gabriela Martinez, Nicholas Nardelli +3
Chip-scale microwave atomic systems based on thermal atomic beams offer a promising approach to realize low-power and low-drift clocks for timing holdover applications. Miniature b…
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…
Atomic clock frequency ratios with fractional uncertainty
Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24
We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and Sr. With total fractional uncertainties at or bel…
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…
High-Stability Single-Ion Clock with Systematic Uncertainty
Mason C. Marshall, Daniel A. Rodriguez Castillo, Willa J. Arthur-Dworschack +10
We report a single-ion optical atomic clock with fractional frequency uncertainty of and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{Ï/\mathrm{…
