University of Sheffield

The University of Sheffield is a UK research university whose physics and electrical engineering departments host quantum research groups. Its quantum work is primarily academic — covering quantum information theory, quantum optics and photonic device research, including single-photon sources and integrated photonics — and it participates in UK national quantum research programmes rather than selling quantum hardware. The university is not a company: it licenses technology and spawns spinouts, though it is a minor player compared with dedicated quantum firms or larger research centres.

Quantum codes correct errors even with qubit loss or gain

Researchers at the University of Sheffield have shown that permutation-invariant quantum error-correcting codes can handle synchronisation errors, where qubits are lost from or added to a register. The work establishes an equivalence between insertions and deletions in this setting, widening the class of errors that quantum codes can correct.

OutlookPlausible

This could let photonic quantum systems treat photon loss as a correctable deletion error rather than a fatal fault, reducing the need for postselection.
