Fidelity threshold of the surface code beyond single-qubit error models

P Jouzdani, E Novais, IS Tupitsyn, ER Mucciolo - Physical Review A, 2014 - APS
The surface code is a promising alternative for implementing fault-tolerant, large-scale
quantum information processing. Its high threshold for single-qubit errors under stochastic …

Fidelity of the surface code in the presence of a bosonic bath

P Jouzdani, E Novais, ER Mucciolo - … Review A—Atomic, Molecular, and Optical …, 2013 - APS
We study the resilience of the surface code to decoherence caused by the presence of a
bosonic bath. This approach allows us to go beyond the standard stochastic error model …

Surface code fidelity at finite temperatures

E Novais, AJ Stanforth, ER Mucciolo - Physical Review A, 2017 - APS
We study the dependence of the fidelity of the surface code in the presence of a single finite-
temperature massless bosonic environment after a quantum error correction cycle. The three …

Long-time efficacy of the surface code in the presence of a super-Ohmic environment

DA López-Delgado, E Novais, ER Mucciolo… - Physical Review A, 2017 - APS
We study the long-time evolution of a quantum memory coupled to a bosonic environment
on which quantum error correction (QEC) is performed using the surface code. The …
