Accurate optimal quantum error correction thresholds from coherent information
Luis Colmenarez, Ze-Min Huang, Sebastian Diehl +1
Quantum error correcting (QEC) codes protect quantum information from decoherence, as long as error rates fall below critical error thresholds. In general, obtaining thresholds imp…
Ergodic inclusions in many body localized systems
Luis Colmenarez, David J. Luitz, Wojciech De Roeck
We investigate the effect of ergodic inclusions in putative many-body localized systems. To this end, we consider the random field Heisenberg chain, which is many-body localized at…
Refining the weighted subspace-search variational quantum eigensolver: compression of ansätze into a single pure state and optimization of weights
Cheng-Lin Hong, Luis Colmenarez, Lexin Ding +2
The weighted subspace-search variational quantum eigensolver (SSVQE) is a prominent algorithm for calculating excited-state properties of molecular quantum systems. In this work, w…
