光量子電腦 Optical/Photonic Quantum Computers(OQCs): Basics, Advances & Trends (v7) P.3 - Light Quantum (Photon) | 黃光旭 (KS John Huang) P.4 - Methodology: the way of light What’s light quantum (photon)? Why Optical/Photonic QC (OQC)? [All computation models and their underlying physics and phenomena, from the Universe to CPUs/DNA/daily clerking etc., coold be equivalent (with the same equivalent fundamental principle with different limited cases)] P.25 - Basics (Phase I): 1980’s to now OQC technologies based more on 1st Quantization (Interferences) (Variational V-OQC architecture design concept throughout my career) P.43 - Advances (Phase II): 2000’s to now OQC technologies based more on 2nd Quantization (operators with qubits) P.76 - Trends
