A team at the University of Sydney and Microsoft, in collaboration with Stanford University in the US, has miniaturised a component that is essential for the scale-up of quantum computing.
Manipulation of these materials provide a pathway to construct the circuitry needed for the interaction between quantum and classical systems, vital for building a practical quantum computer.
Similar devices are found in mobile phone base-stations and radar systems, and will be required in large quantities in the construction of quantum computers.
The leader of the Sydney team, Professor David Reilly, explained that the work to scale-up quantum computing is driving breakthroughs in related areas of electronics and nanoscience.
“It is not just about qubits, the fundamental building blocks for quantum machines. Building a large-scale quantum computer will also need a revolution in classical computing and device engineering,” Professor Reilly said.
Lead author of the paper and PhD candidate Alice Mahoney said: “Such compact circulators could be implemented in a variety of quantum hardware platforms, irrespective of the particular quantum system used.”
