We construct a fault-tolerant quantum error-correcting protocol based on a qubit encoded in
a large spin qudit using a spin-cat code, analogous to the continuous-variable cat encoding …

The physical symmetries of a system play a central role in quantum error correction. In this
work we encode a qubit in a collection of systems with angular momentum symmetry (spins) …

The design of translation symmetric bosonic codes, eg, Gottesmann-Kitaev-Preskill and
squeezed cat codes, is robust against photon loss, but the computation accuracy is limited …

Bosonic quantum error correction codes encode logical qubits in the Hilbert space of one or
multiple harmonic oscillators. A prominent class of bosonic codes are Gottesman-Kitaev …

Spin ensembles are promising quantum technological platforms, but their utility relies on the
ability to perform quantum error correction (QEC) for the specific decoherence in these …

Quantum repeaters that incorporate quantum error correction codes have been shown to be
a promising alternative compared with the original quantum repeaters that rely upon …
