Quantum gates in coupled quantum dots controlled by coupling modulation
Alejandro D. Bendersky, Sergio S. Gomez, Rodolfo H. Romero
We studied the dynamics of a pair of single-electron double quantum dots (DQD) under longitudinal and transverse static magnetic fields and time-dependent harmonic modulation of th…
Efficient electron transfer in quantum dot chains controlled by a cubic detuning profile via shortcuts to adiabaticity
María E. Rus, Rodolfo H. Romero, Sergio S. Gomez
Long-distance fast and precise transfer of charge in semiconductor nanostructures is one of the goals for scalable electronic devices. We study theoretically the control of shuttli…
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…
Quantum transport through single and multilayer icosahedral fullerenes
Daniel A. Lovey, Rodolfo H. Romero
We use a tight-binding Hamiltonian and Green functions methods to calculate the quantum transmission through single-wall fullerenes and bilayered and trilayered onions of icosahedr…
Quantum interference through gated single-molecule junctions
Daniel A. Lovey, Rodolfo H. Romero
We discuss the general form of the transmission spectrum through a molec- ular junction in terms of the Green function of the isolated molecule. By introducing a tight binding meth…
