Flexible and experimentally feasible shortcut to quantum Zeno dynamic passage
2016
Abstract We propose and discuss a theoretical scheme to speed up Zeno dynamic passage by an external acceleration Hamiltonian. This scheme is a flexible and experimentally feasible acceleration because the acceleration Hamiltonian does not adhere rigidly to an invariant relationship, whereas it can be a more general form ∑ u j ( t ) H c j . Here H c j can be arbitrarily selected without any limitation, and therefore one can always construct an acceleration Hamiltonian by only using realizable H c j . Applying our scheme, we finally design an experimentally feasible Hamiltonian as an example to speed up an entanglement preparation passage.
