General tensor network decoding of 2D Pauli codes
Christopher T. Chubb
In this work we develop a general tensor network decoder for 2D codes. Specifically, we propose a decoder that approximates maximally likelihood decoding for 2D stabiliser and subs…
Tailoring surface codes for highly biased noise
David K. Tuckett, Andrew S. Darmawan, Christopher T. Chubb +3
The surface code, with a simple modification, exhibits ultra-high error correction thresholds when the noise is biased towards dephasing. Here, we identify features of the surface…
Avoiding irreversibility: engineering resonant conversions of quantum resources
Kamil Korzekwa, Christopher T. Chubb, Marco Tomamichel
We identify and explore the intriguing property of resource resonance arising within resource theories of entanglement, coherence and thermodynamics. While the theories considered…
Moderate deviation analysis of majorisation-based resource interconversion
Christopher T. Chubb, Marco Tomamichel, Kamil Korzekwa
We consider the problem of interconverting a finite amount of resources within all theories whose single-shot transformation rules are based on a majorisation relation, e.g. the re…
