Materialised symmetries of 2D translationally invariant codes
Andrew Li, Stephen D. Bartlett, Andrew C. Doherty +1
There has been significant recent interest in near-term qLDPC codes as high-performance alternatives to surface and color codes. One such class of codes is 2-dimensional translatio…
Quantifying Pauli Errors in Single-Photon Resource-State Generation
Yuktee Gupta, Andrew C. Doherty, Sahand Mahmoodian
We propose a scheme to compute Pauli error rates in photonics-based quantum error correction using experimental observables of single photons produced from quantum emitters. We sho…
Ising on the donut: Regimes of topological quantum error correction from statistical mechanics
Lucas H. English, Sam Roberts, Stephen D. Bartlett +2
Utility-scale quantum computers require quantum error correcting codes with large numbers of physical qubits to achieve sufficiently low logical error rates. The performance of qua…
Explicit Instances of Quantum Tanner Codes
Rebecca Katharina Radebold, Stephen D. Bartlett, Andrew C. Doherty
We construct several explicit instances of quantum Tanner codes, a class of asymptotically good quantum low-density parity check (qLDPC) codes. The codes are constructed using dihe…
Decomposition of any quantum measurement into extremals
G. Sentís, B. Gendra, S. D. Bartlett +1
We design an efficient and constructive algorithm to decompose any generalized quantum measurement into a convex combination of extremal measurements. We show that if one allows fo…
Multiple-copy state discrimination: Thinking globally, acting locally
B. L. Higgins, A. C. Doherty, S. D. Bartlett +2
We theoretically investigate schemes to discriminate between two nonorthogonal quantum states given multiple copies. We consider a number of state discrimination schemes as applied…
