OptQC
Scalable optical quantum computers operating at room temperature
About OptQC
OptQC is a deep-tech spin-off from the University of Tokyo dedicated to commercializing the world’s first scalable, general-purpose optical quantum computer. Emerging from the renowned Furusawa Laboratory, the company leverages a unique continuous-variable approach that enables quantum processing to function at room temperature, eliminating the need for the massive dilution refrigerators required by superconducting competitors.
The company’s core innovation lies in "time-domain multiplexing" technology, which allows for the generation of large-scale quantum entanglement on a single optical circuit. By processing information using light pulses rather than static physical qubits, OptQC aims to achieve unprecedented scalability—targeting systems with over 10,000 modes. This architecture promises to deliver fault-tolerant, high-speed quantum computing power capable of solving complex combinatorial optimization and chemical simulation problems.
Headquartered in Tokyo, OptQC is rapidly transitioning from academic breakthrough to industrial application with backing from major investors like Global Brain and UTokyo IPC. The company is positioning itself as a key player in the "Post-5G" information infrastructure, utilizing significant venture capital and government support to build energy-efficient quantum hardware that can be deployed in standard data center environments.
