Why We’re Here
Overcoming the Limits of Quantum Scalability
Today’s quantum computers remain monolithic and disconnected from communication channels, limiting scalability, restricting use to single users and locations, and creating a fundamental bottleneck to achieving quantum advantage in both computing and communication.
We are developing quantum interconnect hardware to overcome this bottleneck, enabling the transition to modular, networked quantum systems

Our Quantum Interconnect Design Principles
-
QPU Centric is EssentialDirect physical integration with the QPU—rather than off-unit connections—ensures both speed and fidelity in quantum computing. -
Optical Fiber Stays Effective in QuantumOptical fiber retains its dominant capabilities and unique position, even with the rise of silicon photonics. -
Cavity QED Unlocks EfficiencyOperating with a low-loss cavity is critical for achieving efficient conversion between matter qubits and flying qubits.
We’re a global-minded team rooted in Japan’s engineering excellence, solving tough, high-impact problems with scalable, sustainable solutions for the quantum ecosystem.
Core Technology
Ultra-Low-Loss Nanofiber Cavity Engineered for QPUs
Cavity Quantum Electrodynamics (QED) is a well-established field of physics and a powerful platform for coupling stationary and flying qubits — essential for modular and networked quantum computing. Its adoption, however, has long been limited by the challenge of creating a cavity that is both QPU-ready and seamlessly integrable.
We have overcome this challenge. Leveraging over a decade of engineering innovation, we have developed a proprietary nanofiber cavity that unlocks the advantage of cavity QED while maintaining compatibility with optical fiber and existing QPU architectures — enabling strong atom–photon coupling and paving the way for scalable quantum interconnects.
