About
QphoX is a Dutch quantum transduction company based in Delft, spun out of QuTech and TU Delft. It develops the world's first Quantum Transducer, a device that converts quantum information between microwave and optical frequencies over fiber at room temperature, allowing superconducting quantum computers to network over optical fiber. QphoX launched its first commercial Quantum Transducer product in 2025 and partners with Welinq for optical interconnects. It is a founding member of the Quantum Datacenter Alliance alongside Nu Quantum, OQC, Cisco, NTT DATA, Quantinuum, and QuEra. In September 2025, QphoX and Rigetti won a $5.8M three-year contract from the Air Force Research Laboratory (AFRL) to develop microwave-to-optical quantum transduction. The project pairs QphoX transducers with a Rigetti 9-qubit Novera QPU to build a quantum local area network (QLAN) at AFRL's Rome, NY facility, targeting entanglement between superconducting qubits and optical photons and quantum information transmission over telecom fiber. In March 2026, IBM became the first announced customer for QphoX's commercial Quantum Transducer, pairing it with IBM's Quantum Networking Unit. Update 2026-03-24: QphoX demonstrated that its optical control system is compatible with the Bluefors cryogenic platform for superconducting qubit control.
