New device for scaling up quantum computers
Australian scientists have developed a new cryogenic computer system called
Gooseberry which has potential for scaling up quantum computers from dozens to thousands of qubits.
Quantum computing – as opposed to traditional (or classical ) computing – has been around for many years now. This area of computer science involves the exploitation of physical phenomena such as superposition and entanglement to perform calculations. Unlike the bits of classical computers, which are based on binary ones and zeros, quantum computer qubits can work with multiple values simultaneously. By combining qubits in this way, it quickly becomes possible to work with exponentially larger numbers, with potentially revolutionary applications. If fully realised, quantum computers could solve problems in fields as diverse as cryptography, medicine, finance, artificial intelligence and logistics.

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.

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. To realise the potential of quantum computing, machines will need to operate thousands if not millions of qubits, said Professor David Reilly, a designer of the chip who holds a joint position with Microsoft and the University of Sydney.
