Fuelled by $14 million Series A, NanoQT pushes nanofiber interconnects for scalable quantum processors and networked systems, enabling integration with communication-ready architectures.
US-based Nanofiber Quantum Technologies, Inc. (NanoQT), a quantum computing hardware startup, has closed the first tranche of a $14 million Series A financing. The round was led by existing investor Phoenix Venture Partners (PVP), with Brevan Howard Macro Venture Fund joining as a new investor.
The funding follows over $20 million in government R&D grants in Japan and the United States supporting NanoQT’s technology development.
Other current investors, including WASEDA University Ventures, JAFCO Group, Mirai Creation Fund III, and Keio Innovation Initiative, also participated.
NanoQT’s CEO, Masashi Hirose, said the company’s nanofiber cavity-QED interconnect is intended to facilitate scaling quantum processors and enable integration with quantum communication systems.
The interconnect converts qubit signals into photonic signals with minimal loss, supporting modular quantum processors and potential networked systems. NanoQT’s initial focus is on neutral-atom quantum processing units (QPUs), which face near-term scalability limits.
The technology could also support the emerging quantum repeater market, relevant for long-distance quantum networks.
Proceeds from the Series A will fund a demonstration of a distributed quantum computing system using the interconnect, productisation of the technology, and expansion of engineering and manufacturing facilities in College Park, Maryland, and Tokyo.
NanoQT is headquartered in Palo Alto, California, US, with operations in Maryland and Tokyo. Its research combines cavity quantum electrodynamics with nanofiber interconnects aimed at modular and networked quantum computing.
