Two-dimensional coherent spectroscopy on a series of quantum dot samples with different morphology reveals that biexciton binding is independent of the details of confinement in InAs dots, in… (More)
We report the demonstration of coherent population trapping of an electron spin by means of coherent optical spectroscopy of a single negatively charged quantum dot.
We report the demonstration of the Autler-Townes splitting and Mollow absorption spectrum by means of coherent optical spectroscopy of a strongly driven quantum dot.
We optically generated an electronic state in a single InAs/GaAs self-assembled quantum dot that is a precursor to the deterministic entanglement of the spin of the electron with an emitted photon in… (More)
We demonstrate that the sign of detuning of an optical pulse train from quantum dot resonances controls the direction of nuclear spin flips. This effect can produce a narrow, precise distribution of… (More)
We demonstrate entanglement between an InAs quantum dot (QD) electron spin qubit and a photon. This valuable quantum information resource can be used to mediate spin-spin entanglement between distant… (More)
Coherent nonlinear optical measurements on individual charged quantum dots show trion dipole dephasing rates comparable to single excitons with negligible contributions from pure dephasing. The… (More)
We have observed that the tunneling magnetoconductance between two-dimensional ~2D! electron gases, formed at nominally identical InAs-AlSb interfaces, most often exhibits two sets of Shubnikov–de… (More)
Time and frequency domain nonlinear spectroscopy measurements on a charged GaAs quantum dot ensemble identify negatively charged excitons. Spectral hole burning suggests not all states are strongly… (More)
We demonstrate the optical initialization and ultrafast coherent control of an electron spin in a self-assembled dot, showing a spin Rabi oscillation and time-resolved precession of the electron spin… (More)
