Surface codes are well-suited to the superconducting circuit-based quantum computers being developed by Google and IBM, whose physical qubits are arranged in exactly this kind of grid. But each ...

Quantum error‐correcting codes (QECCs) have emerged as a crucial instrument in the quest to realise reliable quantum information processing. These codes utilise sophisticated mathematical frameworks ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...
