Correcting Low Frequency Noise With Continuous Measurement

Abstract

Low frequency noise presents a serious source of decoherence in solid- state qubits. When combined with a continuous weak measurement of the eigenstates of a qubit, the low frequency noise induces a second order relaxation between the qubit states. Here we show that the relaxation provides a unique approach to calibrate the low frequency noise in the time domain. By encoding one qubit with two physical qubits that are alternatively calibrated, quantum logic gates with high fidelity can be performed.
