Control quantum evolution speed of a single dephasing qubit for arbitrary initial states via periodic dynamical decoupling pulses
We investigate the possibility to control quantum evolution speed of a single dephasing qubit for arbitrary initial states by the use of periodic dynamical decoupling (PDD) pulses. It is indicated that the quantum speed limit time (QSLT) is determined by initial and final quantum coherence of the qu...
