IQM Quantum Computers and QphoX partner to develop an optical interface to power superconducting quantum processors

DELFT, The Netherlands, August 31, 2022—(BUSINESS WIRE)– Dutch quantum transduction startup QphoX and Finnish quantum computer manufacturer IQM Quantum Computers have announced a new collaboration to develop a next-generation interface for scaling quantum computers.

IQM is the European leader in building quantum computers, providing them on-site for supercomputer data centers and research laboratories and offering full access to their hardware. IQM supplies these machines as a full-stack system integrator with its own quantum processors using superconducting qubits.

QphoX specializes in the conversion of wavelengths from photonic to quantum technologies and is working to create the world’s first quantum modem, which will enable the networking of quantum processors. This will unlock new applications such as distributed quantum computing between remotely connected quantum processors, solving one of the biggest scaling challenges facing the industry.

The companies will combine their expertise in quantum information processing to create a new scalable interface for communicating with quantum processors via optical interconnects.

Today’s quantum processors will need to grow significantly in size to tackle real-world applications. One of the main obstacles is that microwave quantum processors must operate in a demanding cryogenic environment while being controlled by microwave lines and cryogenic amplifiers that generate considerable heat, thus limiting the size of the processor. As manufacturers move toward larger chips, it is critical to find scalable approaches that will ultimately enable computers with hundreds of thousands of qubits.

“Using our microwave-to-optical conversion technology, signals can instead be routed through the cryostat via fiber optics. As a result, the space charge and heat limitations placed on the cryostat will be reduced, allowing larger processors to be incorporated into a single cryostat. We are very excited to embarked on this new partnership. We have already been working with IQM processors over the past few months and have been very impressed with the quality and performance,” said Frederick Hijazi, COO and co-founder of QphoX.

“Future large-scale quantum computers require technologies for optical communication or cryogenic signal generation, or both. We find QphoX’s experience and technology plans a promising alternative for communicating control and readout signals from a quantum computer to a qubit chip.” using fiber optics. This collaboration will become an enabler for systems beyond 1000 qubits through the simplification of cabling and new product innovation,” said Dr. Juha Vartiainen, COO and co-founder of IQM Quantum Computers.
