Warwick researchers propose new approach to connect quantum computers at scale

Researchers at the University of Warwick have proposed a new technique that could help overcome one of the biggest challenges facing large-scale quantum computing by enabling quantum information to travel efficiently across semiconductor chips.

Working with Canada’s National Research Council (NRC), the research team has developed the concept of Quantum Phononic Links (QPLs), which would use phonons, microscopic mechanical vibrations within semiconductor materials, to transfer quantum information between qubits over long distances.

The University of Warwick carries out research across areas including quantum technologies, advanced materials, engineering, artificial intelligence and manufacturing. Its physics department is involved in developing semiconductor materials and quantum devices that could support future commercial quantum computing systems.

Dr Maksym Myronov, from the University of Warwick’s Department of Physics, said: “One of the key challenges in quantum computing is long-range qubit connectivity.

“Our work introduces a new concept in which phonons act as a quantum bus, enabling distant qubits to exchange quantum information while remaining fully compatible with semiconductor technology.”

Current quantum processors generally allow direct communication only between neighbouring qubits, making it difficult to build larger systems capable of tackling complex scientific and industrial problems.

The proposed Quantum Phononic Links would instead allow qubits located across an entire semiconductor wafer to communicate through carefully controlled mechanical vibrations travelling within the chip.

The concept relies on compressively strained germanium on silicon, a semiconductor material developed at the University of Warwick using epitaxial growth techniques. Researchers believe the approach could provide a more practical route to building quantum processors containing millions of qubits while remaining compatible with existing semiconductor manufacturing processes.

If successfully demonstrated, the technology could reduce the need for additional communication hardware currently required to connect distant qubits.
