Towards quantitative understanding of quantum dot ensemble capacitance-voltage spectroscopy
Nico F. Brosda, Phil J. Badura, İsmail Bölükbaşı +6
Inhomogeneous ensembles of quantum dots (QDs) coupled to a charge reservoir are widely studied by using, e.g., electrical methods like capacitance-voltage spectroscopy. We present…
Real-time observation of charge-spin cooperative dynamics driven by a nonequilibrium phonon environment
Kazuyuki Kuroyama, Sadashige Matsuo, Jo Muramoto +6
Quantum dots are recognized as a suitable platform for studying thermodynamic phenomena involving single electronic charges and spins in nano-scale devices. However, such a thermod…
Full Counting Statistics of Spin-Flip/Conserving Charge Transitions in Pauli-Spin Blockade
Sadashige Matsuo, Kazuyuki Kuroyama, Shunsuke Yabunaka +4
We investigate the full counting statistics (FCS) of spin-conserving and spin-flip charge transitions in Pauli-spin blockade regime of a GaAs double quantum dot. A theoretical mode…
Quantum state transfer of angular momentum via single electron photo-excitation from a Zeeman-resolved light hole
Kazuyuki Kuroyama, Marcus Larsson, Jo Muramoto +9
Electron spins in GaAs quantum dots have been used to make qubits with high-fidelity gating and long coherence time, necessary ingredients in solid-state quantum computing. The qua…
Illumination-induced nonequilibrium charge states in self-assembled quantum dots
Sascha R. Valentin, Jonathan Schwinger, Pia Eickelmann +4
We report on capacitance-voltage spectroscopy of self-assembled InAs quantum dots under constant illumination. Besides the electronic and excitonic charging peaks in the spectrum r…
A single eletron-photon pair generation from a single polarization-entangled photon pair
Kazuyuki Kuroyama, Marcus Larsson, Sadashige Matsuo +6
We demonstrate paired generation of a single photo-electron in a quantum dot and a single photon from a single polarization-entangled photon pair that is generated by spontaneous p…
