For quantum computers to go from research curiosities to practically useful devices, researchers need to get their errors under control. New research from Microsoft and Quantinuum has now taken a ...

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 ...

Large-scale quantum computers will inevitably need quantum error correction to protect information against decoherence. Traditional error correction typically ...

In contrast to classical computers, which operate on bits that can only take the basic values 0 and 1, quantum computers operate on "qubits," which can assume any superposition of the computational ...

Heavy hexagonal coding is a type of quantum error-correcting coding in which the edges and vertices of a low-degree graph are assigned auxiliary and physical qubits. While many topological code ...
