Logical Performance of 9 Qubit Compass Codes in Ion Traps with Crosstalk Errors

Quantum Physics 2020-03-17 v2

Abstract

We simulate four quantum error correcting codes under error models inspired by realistic noise sources in near-term ion trap quantum computers: T2T_2 dephasing, gate overrotation, and crosstalk. We use this data to find preferred codes for given error parameters along with logical error biases and a pseudothreshold which compares the physical and logical gate failure rates for a CNOT gate. Using these results we conclude that Bacon-Shor-13 is the most promising near term candidate as long as the impact of crosstalk can be mitigated through other means.
