Eliminating the confined dark-exciton qubit precession using an externally applied magnetic field
Zu-En Su, Dan Cogan, Ido Schwartz +2
We investigate experimentally and theoretically the behavior of the confined dark exciton in an InAs/GaAs semiconductor quantum dot, under the application of an external magnetic f…
Quantum dot molecule devices with optical control of charge status and electronic control of coupling
Frederik Bopp, Jonathan Rojas, Natalia Revenga +13
Tunnel-coupled pairs of optically active quantum dots - quantum dot molecules (QDMs) - offer the possibility to combine excellent optical properties such as strong light-matter cou…
The coherence of quantum dot confined electron- and hole-spin in low external magnetic field
Dan Cogan, Zu-En Su, Oded Kenneth +1
We investigate experimentally and theoretically the temporal evolution of the spin of the conduction band electron and that of the valence band heavy hole, both confined in the sam…
Optical Phase Measurement Using a Deterministic Source of Entangled Multi-photon States
Giora Peniakov, Zu-En Su, Ayal Beck +3
Precision measurements of optical phases have many applications in science and technology. Entangled multi-photon states have been suggested for performing such measurements with p…
Depolarization of Electronic Spin Qubits Confined in Semiconductor Quantum Dots
Dan Cogan, Oded Kenneth, Netanel H. Lindner +6
Quantum dots are arguably the best interface between matter spin qubits and flying photonic qubits. Using quantum dot devices to produce joint spin-photonic states requires the ele…
The Optical Activity of the Dark Exciton
Y. Don, M. Zielinski, D. Gershoni
We present a phenomenological model to consider the effect of shape symmetry breaking on the optical properties of self-assembled quantum dots. We compare between quantum dots with…
Generating single photons at GHz modulation-speed using electrically controlled quantum dot microlenses
A. Schlehahn, R. Schmidt, C. Hopfmann +7
We report on the generation of single-photon pulse trains at a repetition rate of up to 1 GHz. We achieve this high speed by modulating the external voltage applied on an electrica…
Optically Detected Magnetic Resonance Imaging
Aharon Blank, Guy Shapiro, Ran Fischer +2
Optically detected magnetic resonance (ODMR) provides ultrasensitive means to detect and image a small number of electron and nuclear spins, down to the single spin level with nano…
Atomistic theory of dark excitons in self-assembled quantum dots of reduced symmetry
M. Zielinski, Y. Don, D. Gershoni
We use an atomistic model to consider the effect of shape symmetry breaking on the optical properties of self-assembled InAs/GaAs quantum dots. In particular, we investigate the en…
Electron-hole spin flip-flop in semiconductor quantum dots
Y. Benny, R. Presman, Y. Kodriano +4
We use temporally resolved intensity cross-correlation measurements to identify the biexciton-exciton radiative cascades in a negatively charged QD. The polarization sensitive corr…
Excitation spectroscopy of single quantum dots at tunable positive, neutral and negative charge states
Y. Benny, Y. Kodriano, E. Poem +3
We present a comprehensive study of the optical transitions and selection rules of variably charged single self-assembled InAs/GaAs quantum dots. We apply high resolution polarizat…

E. Poem, J. Shemesh, I. Marderfeld +6
We present an experimental and theoretical study of the polarized photoluminescence spectrum of single semiconductor quantum dots in various charge states. We compare our high reso…
Emission characteristics of quantum dots in planar microcavities
G. Ramon, U. Mizrahi, N. Akopian +5
The emission properties of single quantum dots in planar microcavities are studied experimentally and theoretically. Fivefold Enhanced spontaneous emission outside the microcavity…
