Fault-Tolerant Landau-Zener Quantum Gates
C. Hicke, L. F. Santos, M. I. Dykman
abstract: We present a method to perform fault-tolerant single-qubit gate operations
using Landau-Zener tunneling. In a single Landau-Zener pulse, the qubit
transition frequency is varied in time so that it passes through the frequency
of the radiation field. We show that a simple three-pulse sequence allows
eliminating errors in the gate up to the third order in errors in the qubit
energies or the radiation frequency.
