Ultralow-loss Si3N4 PICs generate path-encoded EPR pairs (F=0.9875) and fuse them into four-photon GHZ states at F=0.943(8) and 27 Hz—two orders of magnitude above prior silicon-photonic rates.
Hybrid cryogenic-cavity plus chip-scale Brillouin laser delivers <1 Hz linewidth and 0.2 Hz²/Hz noise above 10 MHz, enabling sub-Hz spectroscopy in a 3D 87Sr clock.
A centimeter-scale dynamic optical cavity with heterodyne readout achieves sub-femtometer per square root Hertz displacement sensitivity above 8 Hz and tracks motions over ten orders of magnitude in range.
A monolithic bow-tie cavity with finesse 5.7e4 is realized for homogeneous coupling to Sr atoms at 689 nm, projected to enable up to 28 dB spin squeezing for quantum-enhanced interferometry.
A heralded single-photon source at telecom wavelengths is realized by combining a narrow-band silicon nitride photon-pair source with GHz-gated InGaAs/InP detectors that provide both timing and spectral filtering.
Asymmetry in bichromatic fields produces additional nonlinear error-signal frequency shifts in CPT spectroscopy at phase-jump modulation under unisotropic relaxation, while conventional harmonic modulation yields more linear shifts in the high-frequency regime for non-short integration times.
FPGA feedforward system with high-efficiency homodyne detector achieves 196 ns total latency and >95% quantum efficiency for real-time CV MB-QIP.
Describes a fiber-coupling setup for Bruker IFS 125 FTS with hexagonal fibers for mode scrambling and dichroic combining for dual-source measurements.
