Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

Researchers at RIKEN have demonstrated experimentally that a microwave photonic circuit device known as a Josephson traveling-wave parametric amplifier (JTWPA) can achieve the low-noise, high-gain ...

The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...

Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But ...

A novel quantum computer - described as launching the journey into unknown dimensions - has officially been put into ...

Over in the UK, quantum computing company Quantum Motion has debuted an industry-first quantum computer, manufactured entirely with a standard silicon CMOS chip fabrication process. This fabrication ...

Ever since Academia Sinica announced a 5-qubit superconducting quantum computer in January 2024, and National Tsing Hua University unveiled a photonic quantum computer capable of integer factorization ...

Alphabet Inc.’s Google ran an algorithm on its “Willow” quantum-computing chip that can be repeated on similar platforms and outperform classical supercomputers, a breakthrough it said clears a path ...

The quantum computing industry is advancing, but is it advancing fast enough? While we constantly hear claims like a quantum computer could be 20,000 times faster, the actual physical processors — the ...

Quantum computing has long promised to revolutionize everything from drug discovery to climate modeling--but until now, even the most advanced quantum machines could only run one program at a time.

There is still no sign of activity at the site slated to house a quantum computer that has nearly $1 billion in government backing.
