PRX Quantum: Silicon Emitters Hit 20 μs Coherence—10× Improvement Over Nanophotonic Devices Silicon is emerging as a platform for a future quantum internet, but a key challenge has been creating stable single photons from silicon-based emitters with a consistent wavelength. Researchers have demonstrated a ten-fold increase in optical coherence time, reaching 20 microseconds, by integrating emitters into Fabry-Perot resonators instead of nanophotonic devices. https://quantumzeitgeist.com/mediatum-silicon-emitters-coherence-prx-quantum/
