Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks. For ...

The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and ...

This encoding method allows quantum information to retain enough data, even in the presence of noise and interference, to detect and correct errors. An efficient quantum encoding scheme can enhance ...

Critics of quantum computers have argued that the supposed advantage these machines have over regular computers have often relied on tests involving pointless tasks. Now, the team at Google Quantum AI ...

Google has demonstrated a 13,000 times speedup for the Quantum Echoes algorithm using its Willow quantum chip. The feat is repeatable, according to the company, and it paves the way toward real-world ...
