Launched March 2026, this device enables high-fidelity conversion of quantum states between microwave superconducting qubit signals and optical fiber-compatible photons, allowing quantum information to be transmitted across standard optical networks at room temperature. Leverages photonic integration, MEMS, and superconducting nanofabrication with a single-photon interface. IBM is the first partner to integrate the device, connecting superconducting qubits for distributed quantum computing prototypes.
Next-generation product (targeted for 2027 release) that will serve as a full modular quantum networking device for connecting quantum computers over optical fiber networks. Designed to enable distributed and modular quantum computing architectures in data centers and ultimately form the backbone of a quantum internet. Built on TU Delft QuTech research; currently in development following the initial Quantum Transducer commercial launch.
