What Nanofiber Quantum Technologies does

Nanofiber Quantum Technologies (NanoQT) is a private quantum hardware company founded in 2022 in Tokyo that designs and builds nanofiber cavity-QED interconnects to link quantum processing units (QPUs) into modular, networked systems. Its core technology is a proprietary ultra-low-loss nanofiber cavity — a millimeter-scale nanophotonic structure fabricated directly from optical fiber — which delivers <1 dB/m loss, +1mm cavity length, and +4000 finesse, enabling strong atom-photon coupling at telecom wavelengths without cryogenic cooling. The product portfolio spans three layers: the Ultra-Low-Loss Nanofiber Cavity (component), the High-Bandwidth Quantum Interconnect (system linking QPUs via photons), and the Nanofiber Cavity-QED Interconnect (commercial product targeting neutral-atom QPU integration). Supporting protocols include CAPS for >100 kHz entanglement rates with fidelity >0.999, entanglement boosting achieving logical error rates near 10^-12, and a satellite-assisted global network architecture distributing over 10,000 Bell pairs per pass at >90% fidelity.

The company targets two primary customer segments: neutral-atom quantum computing hardware manufacturers needing modular scaling solutions, and academic/government research laboratories working on quantum networking. Revenue mechanics are split between (i) hardware sales of quantum interconnect products — still in productization per Series A use of funds — (ii) R&D grants, with over US$20 million from Japanese programs (NEDO PCA Phase ~$5.6M, NEDO Post-5G, prior STS) and US sources, and (iii) future licensing potential. Go-to-market is direct enterprise engagement with quantum hardware developers and research institutions, supported by scientific thought leadership through peer-reviewed publications, conferences, and partnerships such as the QuEra integration MoU (March 2025) and VeriQloud blind quantum computing collaboration (June 2025).

Operations span Tokyo (R&D and primary manufacturing), Palo Alto (US headquarters and business office), and College Park, Maryland (engineering and manufacturing expansion). The company is venture-backed with ~$24 million in equity raised across a 2023 seed and a September 2025 Series A led by Phoenix Venture Partners. Founders include Masashi Hirose (CEO, MIT PhD, ex-McKinsey), Akihisa Goban (CTO, Caltech PhD), and Prof. Takao Aoki (CSO, Waseda University); advisory bench includes Nobel Laureate John Martinis (UCSB) and Prof. Vladan Vuletic (MIT). Revenue is not publicly disclosed.

Core offering

Nanofiber Quantum Technologies manufactures ultra-low-loss nanofiber cavity-QED hardware that serves as a quantum interconnect between separate quantum processing units (QPUs). The hardware enables direct physical integration with neutral-atom QPUs and converts stationary matter qubits into flying photonic qubits over standard optical fiber, allowing modular, networked quantum computing. The company sells these interconnect products to quantum hardware manufacturers and research institutions, supported by government R&D grant funding.

Product overview

NanoQT offers a unified product architecture centered on its proprietary nanofiber cavity technology, which serves as the foundation for quantum interconnect hardware. The core product line consists of the Ultra-Low-Loss Nanofiber Cavity (the fundamental component), the High-Bandwidth Quantum Interconnect (the system-level product that integrates nanofiber cavities to link QPUs), and the Nanofiber Cavity-QED Interconnect (the commercial product targeting neutral-atom QPU integration). These products work together as an end-to-end solution: the nanofiber cavity enables efficient atom-photon interfaces at the component level, which are integrated into high-bandwidth quantum interconnects that connect separate QPUs into modular, networked quantum computing systems, addressing the scalability bottleneck in fault-tolerant quantum computing.
