Four-Channel Parallel Broadband Quantum Entropy Source for True Random Number Generation at 100 Gbps
Ken Tanizawa, Kentaro Kato, Fumio Futami · Conference on Lasers and Electro-Optics · 2022
We demonstrate a spatially-multiplexed quantum entropy source with a low-loss 1×8 Silica PLC splitter. Four-channel quantum randomness with 4-GHz/ch bandwidth, based on vacuum fluctuations, is generated, and random bits at 100 Gbps are extracted offline.
