Nanofiber Quantum Technologies, Inc.

Nanofiber Quantum Technologies says it is building infrastructure for networked quantum computing through cavity-QED-based, fiber-native interconnects. On its website, the company describes a proprietary nanofiber cavity designed to couple stationary and flying qubits while remaining compatible with optical fiber and existing QPU architectures. It presents this as quantum interconnect hardware intended to connect quantum processing units with photons.

The company specifically states that its interconnects integrate with neutral atom QPUs and are adaptable to neutral atom computing operations such as Rydberg gates. Its published and highlighted work also includes a neutral-atom architecture simulation framework and research on coupling a reconfigurable ytterbium atom array to a telecom-band nanofiber cavity. NanoQT says it was co-founded in 2022, has business offices in Tokyo, Palo Alto, and College Park, and is rooted in Japan. Its website also lists a first closing of a $14 million Series A funding round in September 2025 and a NEDO PCA phase selection with an over $5.6 million subsidy in June 2026.
