Quantum phase estimation algorithm in presence of static imperfections

Quantum Physics 2009-11-13 v1 Superconductivity

Abstract

We study numerically the effects of static imperfections and residual couplings between qubits for the quantum phase estimation algorithm with two qubits. We show that the success probability of the algorithm is affected significantly more by static imperfections than by random noise errors in quantum gates. An improvement of the algorithm accuracy can be reached by application of the Pauli-random-error-correction method (PAREC).
