“High-fidelity four-photon GHZ states on chip” published on Quantum Information
Mutually entangled multi-photon states are at the heart of all-optical quantum technologies. While impressive progress has been reported in the generation of such quantum light states using free space apparatus, high-fidelity high-rate on-chip entanglement generation is crucial for future scalability. In this work, we use a bright quantum-dot based single-photon source to demonstrate the high … Continua a leggere
