Coherent control and suppressed nuclear feedback of a single quantum dot hole qubit
Kristiaan De Greve, Peter L. McMahon, David Press +8
Future communication and computation technologies that exploit quantum information require robust and well-isolated qubits. Electron spins in III-V semiconductor quantum dots, whil…
Nuclear Feedback in a Single Electron-Charged Quantum Dot under Pulsed Optical Control
Thaddeus D. Ladd, David Press, Kristiaan De Greve +7
Electron spins in quantum dots under coherent control exhibit a number of novel feedback processes. Here, we present experimental and theoretical evidence of a feedback process bet…
Pulsed Nuclear Pumping and Spin Diffusion in a Single Charged Quantum Dot
Thaddeus D. Ladd, David Press, Kristiaan De Greve +7
We report the observation of a feedback process between the nuclear spins in a single charged quantum dot and its trion transition, driven by a periodic sequence of optical pulses.…
In-plane electronic anisotropy in underdoped Ba(FeCo)As revealed by detwinning in a magnetic field
Jiun-Haw Chu, James G. Analytis, David Press +4
We present results of angle-dependent magnetoresistance measurements and direct optical images of underdoped Ba(FeCo)As which reveal partial detwinning by actio…
Photon Antibunching from a Single Quantum Dot-Microcavity System in the Strong Coupling Regime
David Press, Stephan Goetzinger, Stephan Reitzenstein +5
We observe antibunching in the photons emitted from a strongly-coupled single quantum dot and pillar microcavity in resonance. When the quantum dot was spectrally detuned from the…
Quantum Degenerate Exciton-Polaritons in Thermal Equilibrium
H Deng, D Press, S Gotzinger +4
We study the momentum distribution and relaxation dynamics of semiconductor microcavity polaritons by angle-resolved and time-resolved spectroscopy. Above a critical pump level, th…
