Mitsubishi Electric Corporation and Nanofiber Quantum Technologies have embarked on a collaborative project to pioneer neutral-atom quantum computer interconnection technologies. The joint endeavor aims to culminate in a technology demonstration by the conclusion of March 2026.
This ambitious project seeks to harness core optical quantum interface technologies that merge qubit control and nanofibre cavity technologies specifically designed for neutral-atom quantum computers. These computers hold promise in scalability due to their high integration capabilities and the utilization of optical tweezers for flexible atom arrangement control.

Despite the advantages offered by neutral-atom quantum computers, such as scalability and integration capabilities, limitations exist in terms of the number of qubits controllable within a single system. Factors like spatial constraints for atom arrangement necessitate technological advancements to interconnect multiple quantum computers and expand qubit numbers for large-scale quantum computing feasibility.
The project’s focal point is the development of a photonic quantum interface by amalgamating Mitsubishi Electric’s cutting-edge qubit control technologies with NanoQT’s expertise in combining Yb atoms with nanofibre cavities. The primary objective is to showcase highly efficient interconnection technology between neutral Yb atom quantum computers.
The envisioned atom-photon interface is poised to facilitate efficient interconnections between neutral-atom quantum computers. Leveraging nanofibre cavities to amplify atom-photon interactions will significantly enhance quantum entanglement generation efficiency, crucial for inter-quantum computer communication.
Moreover, the project will explore storing multiple Yb atoms in nanofibre cavities to parallelize entanglement sharing. These advancements, coupled with Mitsubishi Electric’s qubit control technologies, are anticipated to enable high-speed, large-capacity communication between quantum computers.
Mitsubishi Electric and NanoQT are committed to expeditiously prototyping and establishing fundamental technologies essential for large-scale quantum computing. Future endeavors will focus on demonstrating optimized quantum-state transfer efficiency to refine control technologies through nanofibre cavities, with the ultimate goal of constructing a distributed quantum computing platform to tackle real-world industrial challenges.
As the realm of computer technology continues to push boundaries, collaborations such as the one between Mitsubishi Electric and Nanofiber Quantum Technologies represent a significant stride towards unlocking the potential of quantum computing. The fusion of expertise and resources from both entities underscores a shared commitment to innovation and the advancement of computing capabilities.
