About Nanofiber Quantum Technologies
Nanofiber Quantum Technologies (NanoQT) is a Tokyo-based quantum hardware startup specializing in nanofiber cavity Quantum Electrodynamics (QED). Spun off from Waseda University in 2022, the company develops a unique hybrid architecture that integrates stable neutral atoms (as qubits) with photons (as information carriers) within an all-fiber environment. This proprietary technology overcomes the scaling limitations of traditional quantum systems by enabling high-fidelity, long-distance connectivity over existing fiber-optic infrastructures. NanoQT’s core product is a fiber-connectable Quantum Processing Unit (QPU) that doubles as a quantum repeater and interconnect. By facilitating seamless atom-photon interaction, NanoQT provides the essential "missing link" for distributed quantum computing and the establishment of a secure Quantum Internet. As a strategic enabler for NIF Security of Critical Technologies, NanoQT ensures the future of ultra-secure communications and scalable quantum power through a platform that is natively compatible with global telecommunications networks.
