Nanofiber Quantum Technologies, Inc. (NanoQT), a quantum computing company, has announced the first closing of its $14 million Series A financing. The round was led by existing investor Phoenix Venture Partners (PVP), with new participation from Brevan Howard Macro Venture Fund. Existing investors WASEDA University Ventures, Inc. (WUV), JAFCO Group Co Ltd, Mirai Creation Fund III (SPARX Asset Management Co., Ltd.), and Keio Innovation Initiative, Inc. (KII) also participated. The financing follows more than $20 million in government R&D grants from Japan and the United States that support NanoQT’s roadmap.
NanoQT’s core technology is a proprietary nanofiber-cavity interconnect, which functions as an ultra-low-loss fiber-optic interconnect. The device is designed to enable the efficient conversion of qubit signals into photonic signals, a capability grounded in cavity quantum electrodynamics (QED). The company’s initial product is engineered for neutral-atom QPUs, with the goal of enabling distributed and networked quantum computing.
The company intends to use the proceeds to accelerate the development and productization of its nanofiber-cavity interconnect and to expand its engineering and manufacturing capacity in College Park, Maryland, and Tokyo. Masashi Hirose, Ph.D., CEO and Co-Founder of NanoQT, noted that the interconnect is an essential component for scaling up quantum computing and integrating QPUs with quantum communication capabilities.
