Beyond qubits: next big step to scale up quantum computing Through the Microsoft partnership with the University, Professor David Reilly and colleagues have invented a device that operates at 40 times colder than deep space to directly control thousands of qubits, the building blocks of quantum technology.
The control platform with the cryogenic chip to control thousands of qubits. The invention will help quantum engineers overcome the input-output bottleneck preventing quantum machines scaling to useful devices.
Scientists and engineers at the University of Sydney and Microsoft Corporation have opened the next chapter in quantum technology with the invention of a single chip that can generate control signals for thousands of qubits, the building blocks of quantum computers.
IC can control thousands of Qubits
Researchers at the University of Sydney and Microsoft have come up with a chip that can generate control signals for thousands of qubits, the building blocks of quantum computers.
“To realise the potential of quantum computing, machines will need to operate thousands if not millions of qubits,” says researcher Professor David Reilly.
“The world’s biggest quantum computers currently operate with just 50 or so qubits,” he said, “this small scale is partly because of limits to the physical architecture that control the qubits. Our new chip puts an end to those limits.”
Most quantum systems require quantum bits, or qubits, to operate at temperatures close to absolute zero (-273.15 degrees).
