Tensor Network Decoding Beyond 2D
Christophe Piveteau, Christopher T. Chubb, Joseph M. Renes
Decoding algorithms based on approximate tensor network contraction have proven tremendously successful in decoding 2D local quantum codes such as surface/toric codes and color cod…
Quantum-embeddable stochastic matrices
Fereshte Shahbeigi, Christopher T. Chubb, Ryszard Kukulski +2
The classical embeddability problem asks whether a given stochastic matrix , describing transition probabilities of a -level system, can arise from the underlying homogeneous…
Quantum dichotomies and coherent thermodynamics beyond first-order asymptotics
Patryk Lipka-Bartosik, Christopher T. Chubb, Joseph M. Renes +2
We address the problem of exact and approximate transformation of quantum dichotomies in the asymptotic regime, i.e., the existence of a quantum channel mapping $ρ_1^{…
