Coherent control of bound entangled electrons in a CdMnTe quantum well

Abstract

Abstract Ultrafast laser pulses were used to control the spin state of a pair of entangled, donor‐bound electrons in a CdMnTe quantum well. The entanglement, mediated by an optically‐excited exciton, was characterized by pumpprobe spectroscopy. The data exhibits two dominant oscillations, one at the frequency of the spin‐flip of a donor electron and the second one at twice this frequency. Their amplitudes depend linearly on the pump power. The quantum state of the two‐electron spin system can be controlled by appropriate spatial and temporal shaping of the pump pulses. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Spin control by ultra short laser pulses in a Mn doped quantum dot

Doris E. Reiter, V. M. Axt, T. Kühn

Abstract Optically induced spin flip processes in quantum dots doped with a single Mn atom are discussed. On the femtosecond time scale the exciton can be controlled by ultra short laser pulses. Via the exchange interaction the Mn spin can flip on a picosecond time scale by transferring its angular momentum to the exciton. For a heavy hole system this flipping process can be described in terms of exchange‐induced Rabi oscillations between the bright and dark exciton state accompanied by a flip of the Mn spin. Because of the energy splitting between bright and dark excitons the Rabi oscillations are off‐resonant and a series of laser pulses is required to achieve a complete flip. When a light hole exciton is resonantly excited in addition to the heavy hole exciton we show that a flip of the Mn spin by two can be achieved by a series of light pulses while the exciton system returns to its initial state.

Control of spin dynamics with laser pulses: Generation of entangled states of donor-bound electrons in a Cd1−xMnx Te quantum well

Jiming Bao, Andrea V. Bragas, J. K. Furdyna +1 more

A quantum-mechanical many-particle system may exhibit nonlocal behavior in that measurements performed on one of the particles can affect a second one that is far apart. These so-called entangled states are crucial for the implementation of quantum information protocols and gates for quantum computation. Here, we use ultrafast optical pulses and coherent pump-probe techniques to create and control spin entangled states in an ensemble of up to three non-interacting electrons bound to donors in a ${\mathrm{Cd}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}$Te quantum well. Our method, relying on the exchange interaction between optically excited excitons and the paramagnetic impurities, can in principle be applied to entangle an arbitrarily large number of electrons. A microscopic theory of impulsive stimulated Raman scattering and a model for multi-spin entanglement are presented. The signature of entanglement is the observation of overtones of donor spin-flips in the differential reflectivity of the probe pulse. Results are shown for resonant excitation of localized excitons below the gap, and above the gap where the signatures of entanglement are significantly enhanced. Data is also presented on the generation of coherent excitations of antiferromagnetically coupled manganese pairs, folded acoustic phonons, exciton Zeeman beats and entanglement involving two ${\mathrm{Mn}}^{+2}$ ions.

Coherent control of excitonic excitations in II–VI quantum wells

T. Voss, Hans Georg Breunig, Ilja Rückmann +1 more

Abstract We present results of experimental work in which the coherent‐control technique has been applied to study the coherent manipulation of excitonic polarization in ZnSe quantum‐well samples. We will introduce the linear control of excitonic polarization in pulse‐transmission experiments and afterwards focus on the question if and how the optical transition from the excitonic states to the bound‐biexciton state can be subject to a directed coherent control. The experimental results will be compared to simulations based on a microscopic theory and will also be explained on the base of a phenomenological few‐level model. The overall suitability of coherent control for the investigation of exciton systems in low‐dimensional wide‐gap materials will be discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Coherent control of an asymmetric semiconductor quantum well structure

J. F. Dynes, Emmanuel Paspalakis

Abstract We study coherent control of an asymmetric semiconductor quantum well by simultaneous application of a laser field and its second harmonic. The relative phase of the applied laser fields is externally altered. The electron population and the small signal absorption and dispersion spectra of a weak probe field propagating through such a quantum well structure are computed and are found to be strongly phase dependent.

Coherent control of ground state excitons in the nonlinear regime within an ensemble of self‐assembled InAs quantum dots

Thomas Moldaschl, Thomas G. Muller, Sebastian Golka +3 more

Abstract In this work femtosecond spectral hole burning spectroscopy is used to resonantly excite ground state excitons in an ensemble of self‐assembled InAs/GaAs quantum dots with a strong pump pulse. Two fundamental coherent nonlinear effects are observed with the aid of the intrinsic time‐ and frequency resolution of the setup: The low temperature Rabi oscillation of the two‐level system associated with the excitonic ground state transition and the observation of two‐photon absorption in the surrounding GaAs crystal matrix. The emergence of the latter effect also infers the existence of charged excitons in the nominally undoped QD sample, backed up by the observation of additional spectral holes next to the excitonic transitions.

Coherent manipulation of three‐spin states in a GaAs/AlGaAs triple dot device

Sergei Studenikin, G. C. Aers, Ghislain Granger +5 more

Abstract In this paper we describe our recent experiments on coherent manipulation of electron spin states formed in a highly tunable GaAs/AlGaAs triple quantum dot device. The coherent evolution of spin states is achieved by using fast pulses from an initialization point in the (201) charge configuration region of the stability diagram. We demonstrate the versatility of the triple dot system capable of tuning to different regimes controlled by the width of the (111) region and pulse parameters. In particular we observe Δ'1/2‐Q3/2 (analogue of S‐T+ in a double dot) and Δ'1/2‐Δ1/2 exchange driven oscillations from both sides of the stability diagram involving all three spins.
