A team of scientists and engineers has invented a cryogenic computer chip capable of functioning at temperatures near absolute zero, which could enable a new crop of high performance quantum computers capable of performing calculations with thousands of qubits, or more. Quantum computers, up to now, could only accommodate a few dozen qubits. That s why the new cryo chip is such a breakthrough. ....
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. ....
); //]]>// > By John P. Mello Jr. Feb 3, 2021 4:33 AM PT A step toward engineering a new generation of powerful quantum computers has been made by a team of scientists and engineers at the University of Sydney, Microsoft and EQUS, the Australian Research Council Centre of Excellence for Engineered Quantum Systems. The team, which published their findings in the Jan. 25 issue of Nature Electronics, invented a cryogenic computer chip capable of functioning at temperatures near absolute zero, which could enable a new crop of high performance quantum computers capable of performing calculations with thousands of qubits, or more. Qubits are the quantum equivalent of the bits used by traditional computers. Because qubits aren t binary they don t process information using zeroes and ones they re capable of much faster performance. For a variety of reasons, however, quantum computers, up to now, could only accommodate a few dozen qubits. That s why the new cry ....
Date Time 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. ....

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. ....
