First experimental demonstration of memory-assisted on-demand multimode microwave-to-optical transduction with 0.3-0.4 noise photons at 460-620 microsecond storage in a 171Yb3+:Y2SiO5 crystal at 30 mK.
A TFLN photonic chip achieves gigahertz-rate active manipulation of time-bin quantum states, enabling loophole-free entanglement certification and continuous QKD operation at 25 kbit/s.
A 4H-SiC microring resonator with loaded Q of 1.9e5 produces time-bin entangled photon pairs at 1.35e7 s^-1 mW^-2, 95.55% visibility, and 94.37% fidelity.
