Measuring Clock Precision Without an Ideal Time Reference
Pablo Á. Domínguez, Christopher Chubb, Mischa P. Woods
Characterising physical devices typically requires comparison with more precise reference standards. For clocks, however, this approach is problematic because no physically perfect…
Characterising the precision of a clock without any external time reference
Pablo Á. Domínguez, Christopher Chubb, Mischa P. Woods
Determining a clock's precision usually requires comparison with a better time reference, yet no ideal reference is physically attainable. We show how a single clock can characteri…
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^{…
Tailoring three-dimensional topological codes for biased noise
Eric Huang, Arthur Pesah, Christopher T. Chubb +2
Tailored topological stabilizer codes in two dimensions have been shown to exhibit high storage threshold error rates and improved subthreshold performance under biased Pauli noise…
