Coherent control of localization, entanglement, and state superpositions in a double quantum dot with two electrons
(American Physical Society, 2009-01)
We have recently proposed a quantum control method based on the knowledge of the energy spectrum as a function of an external control parameter. So far, our method has been applied to connect the ground state to target ...
Magnetic field effects on donor transitions in quantum wells
(Pergamon-elsevier Science LtdOxfordInglaterra, 1996)
Effects of in-plane magnetic fields on the electronic cyclotron effective mass and Landé factor in GaAs-(Ga,Al)As quantum wells
(Sociedade Brasileira de Física, 2006)
Reentrant quantum Hall effect in bilayer system at high filling factors
(ELSEVIER SCIENCE BV, 2008)
We report on the measurements of the quantum Hall effect states in double quantum well structures at the filling factors v = 4N + 1 and 4N + 3, where N is the Landau index number, in the presence of the in-plane magnetic ...
Mutual Information and Quantum Discord in Quantum State Discrimination with a Fixed Rate of Inconclusive Outcomes
(MDPI Multidisciplinary Digital Publishing Institute, 2021-01-6)
We studied the mutual information and quantum discord that Alice and Bob share when Bob implements a discrimination with a fixed rate of inconclusive outcomes (FRIO) onto two pure non-orthogonal quantum states, generated ...
Experimental observation of phase-transition-like behavior in an optical simulation of single-qubit game
(2020-08-01)
Phase-transition-like behavior in quantum games has been studied in recent years as a strategy to deal with abrupt changes in the expected payoff of quantum players. More precisely, such behavior is investigated in the ...
Theoretical and experimental study of the excitonic binding energy in GaAs/AlGaAs single and coupled double quantum wells
(2013-07-31)
This paper discusses the theoretical and experimental results obtained for the excitonic binding energy (Eb) in a set of single and coupled double quantum wells (SQWs and CDQWs) of GaAs/AlGaAs with different Al concentrations ...
Magnetoresistance oscillations in multilayer systems: Triple quantum wells
(AMER PHYSICAL SOC, 2009)
Magnetoresistance of two-dimensional electron systems with several occupied subbands oscillates owing to periodic modulation of the probability of intersubband transitions by the quantizing magnetic field. In addition to ...
Temperature dependence of excitonic transitions in AlxGa1-xAs/GaAs quantum wells
