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 ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

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 ...

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 ...

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 ...

Quantum chemical calculations rely on expanding molecular wave functions in a set of basis functions, typically Gaussian-type orbitals, to approximate the behaviour of electrons in atoms and molecules ...
