By Sarah Chaney Cambon U.S. employers resumed hiring in January, putting the labor market back into growth mode, but the weak pace of job gains suggested a long road remains for the recovery. The U.S. economy added 49,000 jobs last month. The small January gain came after payrolls fell steeply in December, the first decline since the coronavirus pandemic triggered business shutdowns last spring. The unemployment rate fell to 6.3% in January from 6.7% a month earlier, in part reflecting fewer people searching for jobs. The recovery is only stumbling along at this point, Sarah House, senior economist at Wells Fargo Securities, said. Yes, we managed to eke out a gain, but we re still 9.9 million jobs shy of where we were back in February.

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 cryo chip, called Gooseb

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.

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 Achieve Transformational Breakthrough in Scaling Quantum Computers
2 FEBRUARY 2021
Scientists have developed a new kind of cryogenic computer chip capable of functioning at temperatures so cold, it approaches the theoretical limit of absolute zero.
This cryogenic system, called Gooseberry, lays the groundwork for what could be a revolution in quantum computing – enabling a new generation of machines to perform calculations with thousands of qubits or more, whereas today s most advanced devices comprise only dozens.
The world s biggest quantum computers currently operate with just 50 or so qubits, explains quantum physicist David Reilly from the University of Sydney and Microsoft s Quantum Laboratory.
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).
