Controlled high-fidelity navigation in the charge stability diagram of a double quantum dot
(Iop Publishing, 2015-03)
We propose an efficient control protocol for charge transfer in a double quantum dot. We consider numerically a two-dimensional model system, where the quantum dots are subjected to time-dependent electric fields ...
Classical to quantum correspondence in dissipative directed transport
(American Physical Society, 2015-11)
We compare the quantum and classical properties of the (quantum) isoperiodic stable structures [(Q)ISSs],which organize the parameter space of a paradigmatic dissipative ratchet model, i.e., the dissipative modifiedkicked ...
Exact dynamics of single-qubit-gate fidelities under the measurement-based quantum computation scheme
(Amer Physical Soc, 2012-10-19)
Measurement-based quantum computation is an efficient model to perform universal computation. Nevertheless, theoretical questions have been raised, mainly with respect to realistic noise conditions. In order to shed some ...

General theory of measurement with two copies of a quantum state
(American Physical Society, 2009-07)
We analyze the results of the most general measurement on two copies of a quantum state. We show that by using two copies of a quantum state it is possible to achieve an exponential improvement with respect to known methods ...
Quantum and classical complexity in coupled maps
(American Physical Society, 2017-12)
We study a generic and paradigmatic two-degrees-of-freedom system consisting of two coupled perturbed cat maps with different types of dynamics. The Wigner separability entropy (WSE)—equivalent to the operator space ...
