High-visibility Quantum Interference between Two Independent Semiconductor Quantum Dots achieved

Dawn of solid-state quantum networks
Experimental configuration of quantum interference between two independent solid-state QD single-photon sources separated by 302 km fiber. DM: dichromatic mirror, LP: long pass, BP: band pass, BS: beam splitter, SNSPD: superconducting nanowire single- photon detector, HWP: half-wave plate, QWP: quarter-wave plate, PBS: polarization beam splitter.
