The limits of erasure-based postselection for quantum error mitigation
Sam J. Griffiths, Jamie Friel, Brian Vlastakis
In both classical and quantum error correction, heralded erasures are known to be easier to tolerate than unheralded general stochastic errors. Whilst an established benefit of los…
Elementary local representation densities at all primes via lifting recursions
Samuel Griffiths
Let be a prime and let be a quadratic -lattice with quadratic form . For the local representation density is the stable normalised gro…
Online Gaussian elimination for quantum LDPC decoding
Sam J. Griffiths, Asmae Benhemou, Dan E. Browne
Decoders for quantum LDPC codes generally rely on solving a parity-check equation with Gaussian elimination, with the generalised union-find decoder performing this repeatedly on g…
Union-find quantum decoding without union-find
Sam J. Griffiths, Dan E. Browne
The union-find decoder is a leading algorithmic approach to the correction of quantum errors on the surface code, achieving code thresholds comparable to minimum-weight perfect mat…
