Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

Quantum computers are no longer a physics challenge but an engineering one, and quantum error correction is the heart of what ...

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. May 7 ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

Quantum computers are a little like librarians: both abhor noise. Compared with their classical counterparts, quantum computers are finicky and need a serene environment to perform their calculations ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...

In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, ...

There’s a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

Researchers from Google have demonstrated a new generation of quantum computer, called Willow, which is able to run its random circuit sampling (RCS) benchmark significantly faster than a ...
