Netherlands-based QphoX, founded in 2021, identifies as a quantum transduction company working on the world's first quantum modem device. The device helps connect quantum processors in a network via long-range, low-loss quantum channels to enable quantum communication. By networking separate processors together, the modem will let quantum computers scale beyond tens or hundreds of qubits, enabling them to process complex tasks inaccessible to traditional computers. The device uses a quantum transducer that couples microwave and optical photons through a mechanical intermediary resonator to convert information between the microwave domain and optical telecom frequencies.
Key customers and partnerships
QphoX entered into a collaborative agreement with Rigetti Computing in October 2023 to advance superconducting qubit readout with an optical transducer. In August 2022, Qphox and IQM Quantum partnered to develop a scalable interface for quantum computers. The company collaborated with QuantWare in May 2022 to develop networkable quantum computer technology.
Funding and financials
The company raised EUR 8 million (USD 8.7 million) in a funding round led by QDNL Participations in January 2024 for the launch and development of QphoX's debut products.
