High-fidelity one-qubit operations under random telegraph noise
High-fidelity one-qubit operations under random telegraph noise
We address the problem of implementing high-fidelity one-qubit operations subject to time-dependent noise in the qubit energy splitting. We show with explicit numerical results that high-fidelity bit flip operations may be generated by imposing bounded control fields. For noise correlation times shorter than the time for a $\ensuremath{\pi}$ pulse, the …
