Aperiodic dynamical decoupling sequences in the presence of pulse errors
Dynamical decoupling (DD) is a promising tool for preserving the quantum states of qubits.However, small imperfections in the control pulses can seriously affect the fidelity of decoupling, and qualitatively change the evolution of the controlled system at long times.Using both analytical and numerical tools, we theoretically investigate the effect of …
