NanoQT Selected for NEDO “Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems”

― Development of Quantum Interconnect Hardware Integrable with Neutral Atom QPUs―

Nanofiber Quantum Technologies, Inc. (NanoQT) is pleased to announce that our R&D proposal titled “Development of Quantum Interconnect Hardware for Neutral Atom Systems to Support Next-Generation Quantum Computing Infrastructure” has been selected under the “Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems” (hereafter “this project”) by NEDO (New Energy and Industrial Technology Development Organization) (https://www.nedo.go.jp/koubo/CD3_100396.html).

This project aims to advance the performance of components and materials for quantum computers in preparation for the post-5G era, based on the R&D plan formulated by the Ministry of Economy, Trade and Industry (https://www.meti.go.jp/policy/mono_info_service/joho/post5g/pdf/20250325_kenkyukaihatsukeikaku.pdf). Among its goals is the “Development of quantum computer interface devices,” for which our proposal has been selected.

■ Background

Among all quantum computing architectures, neutral atom systems lead in integration. Yet even this most scalable approach faces challenges in moving beyond tens of thousands of qubits, limited by laser power and optical hardware. To overcome these hurdles, the industry is looking to distributed architectures enabled by　quantum interconnects.

However, developing quantum interconnects comes with high technical barriers in both functionality and performance. In particular, achieving remote entanglement generation rates and fidelities that suffice for error correction is difficult, and requires development in an environment integrated with Quantum Processing Unit (QPU). At present, most demonstrations remain limited to constrained environments.

■ Scope and Goals

Our proposal (“Development of Quantum Interconnect Hardware for Neutral Atom Systems to Support Next-Generation Quantum Computing Infrastructure,” hereafter “this proposal”) aims to develop quantum interconnect hardware that can be integrated with neutral atom QPUs. By the end of FY2027, our goal is to achieve industry-leading entanglement generation rates and fidelities in a QPU-integrated environment.

This proposal will advance the following three development streams in a coordinated manner:

1. Component-Level: Integration of nanofiber cavities at the materials/components level
2. System-Level: Architecture design for distributed quantum computers
3. Integration-Level: Functional demonstrations on neutral atom QPU

Through coordinated progress in three domains, we will break through the limits of current architectures and establish high-speed quantum interconnect technology ready for QPU integration.

This proposal builds on research proposed by our team and published in a peer-reviewed journal (https://journals.aps.org/prxquantum/abstract/10.1103/PRXQuantum.6.010101), with high-speed entanglement generation via cavities at its core.
