Nu Quantum has announced a proof-of-concept Qubit-Photon Interface (QPI), which enables modular and distributed quantum computers by connecting different quantum processing units (QPUs) across quantum networks. The technology facilitates the transfer of quantum information between matter and light, overcoming a key barrier to scaling quantum computing.
The first iteration of the QPI has been integrated into Infleqtion’s ultra-high vacuum chamber, showing successful operation under ultra-high vacuum conditions. The device uses optical microcavities to enhance qubit-photon interaction, featuring nanostructured mirrors aligned with sub-80 picometer precision to maintain qubit stability and entanglement quality.
The QPI aims to significantly boost entanglement rates compared to existing lab methods, with future goals of achieving 100x improvements in quantum networking efficiency. This development targets the need for distributed quantum systems capable of handling hundreds to millions of qubits, essential for large-scale quantum computing applications.
Backed by Innovate UK under Project “Calyx,” Nu Quantum’s QPI technology paves the way for connecting QPUs from different providers and modalities, enabling quantum data centers and supercomputing networks. For more information, visit Nu Quantum’s press release here.
