Quantum control of exciton motion in electric field
Yingjia Li, Jorge Casanova, Xi Chen +1
We study quantum control of classical motion of a two-dimensional exciton by optimizing the time-dependent electric field of a stripe-like gate acting on the exciton and inducing i…

Application of the Pontryagin Maximum Principle to the robust time-optimal control of two-level quantum systems
O. Fresse-Colson, S. Guérin, Xi Chen +1
We study the time-optimal robust control of a two-level quantum system subjected to field inhomogeneities. We apply the Pontryagin Maximum Principle and we introduce a reduced spac…
