Controlled quantum state transfer in spin chains at the Quantum Speed Limit
Diego S. Acosta Coden, Sergio S. Gómez, Alejandro Ferrón +1
The Quantum Speed Limit can be found in many different situations, in particular in the propagation of information through quantum spin chains. In homogeneous chains it implies tha…

Fast optical control of a coded qubit in a triple quantum dot
Diego S. Acosta Coden, Sergio S. Gomez, Rodolfo H. Romero +2
In this work, we study strategies for the optical control, within the dipole approximation, of a qubit encoded in the three-electron states of a triple quantum dot. The system is d…

Optimal control of a charge qubit in a double quantum dot with a Coulomb impurity
Diego S. Acosta Coden, Rodolfo H. Romero, Alejandro Ferrón +1
We study the efficiency of modulated laser pulses to produce efficient and fast charge localization transitions in a two-electron double quantum dot. We use a configuration interac…
