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…
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…
Footprints of hyperfine, spin-orbit, and decoherence effects in Pauli spin blockade
T. Fujita, P. Stano, G. Allison +8
We detect in real time inter-dot tunneling events in a weakly coupled two electron double quantum dot in GaAs. At finite magnetic fields, we observe two characteristic tunneling ti…
Single photoelectron spin detection and angular momentum transfer in a gate defined quantum dot
Takafumi Fujita, Kazuhiro Morimoto, Haruki Kiyama +7
Recent innovations in fabricating nanoscale confined spin systems have enabled investigation of fundamental quantum correlations between single quanta of photons and matter states.…
Tuning the electrically evaluated electron Lande g factor in GaAs quantum dots and quantum wells of different well widths
G. Allison, T. Fujita, K. Morimoto +9
We evaluate the Lande g factor of electrons in quantum dots (QDs) fabricated from GaAs quantum well (QW) structures of different well width. We first determine the Lande electron g…
Parity independence of the zero-bias conductance peak in a nanowire based topological superconductor-quantum dot hybrid device
M. T. Deng, C. L. Yu, G. Y. Huang +3
We explore the signatures of Majorana fermions in a nanowire based topological superconductor-quantum dot-topological superconductor hybrid device by charge transport measurements.…
Single Photoelectron Detection after Selective Excitation of Electron-Heavy Hole and Electron-Light Hole Pairs in Double Quantum Dots
K. Morimoto, T. Fujita, G. Allison +9
We demonstrate the real-time detection of single photogenerated electrons in two different lateral double quantum dots made in AlGaAs/GaAs/AlGaAs quantum wells having a thin or a t…
Observation of Majorana Fermions in a Nb-InSb Nanowire-Nb Hybrid Quantum Device
M. T. Deng, C. L. Yu, G. Y. Huang +3
We report on the observation of excitation of Majorana fermions in a Nb-InSb nanowire quantum dot-Nb hybrid system. The InSb nanowire quantum dot is formed between the two Nb conta…
Thermally driven ballistic rectifer
Jason Matthews, David Sánchez, Marcus Larsson +1
The response of electric devices to an applied thermal gradient has, so far, been studied almost exclusively in two-terminal devices. Here we present measurements of the response t…
