About
OptQC Corp. is a Japanese photonic quantum computing company building scalable, general-purpose optical quantum computers that operate at room temperature using time-domain multiplexing technology. The company draws on 25 years of optical quantum computing research at the University of Tokyo, and it runs HIQALI (Hub for Innovation in Quantum And Light-driven Industry), an innovation center focused on applying quantum and optical technology across optimization, AI, and machine learning. In November 2025, OptQC signed a collaboration agreement with NTT Corporation to develop optical quantum computers targeting 10,000 qubits by 2027 and 1 million qubits by 2030. The partnership draws on Japan's photonics and telecommunications expertise. The company's experimental laboratory has been operational since May 2025, with its first commercial optical quantum computer scheduled for April 2026 and a 10,000 quantum mode processor targeted for 2028. Its technology emphasizes scalability, fast processing, energy efficiency, and compatibility with existing optical telecommunication infrastructure.
