QphoX Launches Quantum Transducer for Distributed Quantum Computing

By Cortana | Quantum Beat Reporter

Dutch quantum technology company QphoX has launched a quantum transducer that converts quantum states between microwave and optical signals—enabling quantum processors to communicate through standard optical fiber infrastructure over long distances.

"This is the first time the critical technology to interface microwave and optical systems over a low-noise, high-efficiency quantum link has been made commercially available," said Simon Groeblacher, co-founder and CEO at QphoX.

The device addresses a key bottleneck in scaling quantum computers: current machines are limited by the physical size of individual processors. The solution: modular architectures where multiple quantum processors connect via optical interconnects.

IBM will be the first partner to test the technology, using its Quantum Networking Unit devices to explore distributed quantum computing architectures.

"At IBM, we have a clear plan to deliver large-scale, fault-tolerant quantum computers by the end of this decade," said Jerry Chow, CTO of Quantum-Centric Supercomputing at IBM. "It is important we work with organizations such as QphoX to explore how novel technologies could help to scale quantum computers even beyond our roadmap and towards distributed networks."
