Trajectory-constrained optimal local time-continuous waveform controls for state transitions in -level quantum systems
Ming Zhang, Jia-Hua Wei, Weiwei Zhou +3
Based on a parametrization of pure quantum states we explicitly construct a sequence of (at most) local time-continuous waveform controls to achieve a specified state transi…
Manipulating quantum information on the controllable systems or subspaces
Ming Zhang, Zairong Xi, Jia-Hua Wei
In this paper, we explore how to constructively manipulate qubits by rotating Bloch spheres. It is revealed that three-rotation and one-rotation Hamiltonian controls can be constru…
Optimal control of population transfer in Markovian open quantum systems
Wei Cui, Zairong Xi, Yu Pan
There has long been interest to control the transfer of population between specified quantum states. Recent work has optimized the control law for closed system population transfer…
Optimal control of non-Markovian open quantum systems via feedback
Zairong Xi, Wei Cui, Yu Pan
The problem of optimal control of non-Markovian open quantum system via weak measurement is presented. Based on the non-Markovian master equation, we evaluate exactly the non-Marko…
Non-Markovian entanglement dynamics in coupled superconducting qubit systems
Wei Cui, Zairong Xi, Yu Pan
We theoretically analyze the entanglement generation and dynamics by coupled Josephson junction qubits. Considering a current-biased Josephson junction (CBJJ), we generate maximall…
Optimal Dynamical Decoupling Sequence for Ohmic Spectrum
Yu Pan, Zairong Xi, Wei Cui
We investigate the optimal dynamical decoupling sequence for a qubit coupled to an ohmic environment. By analytically computing the derivatives of the decoherence function, the opt…
