Tunable Indistinguishable Photons From Remote Quantum Dots
R. B. Patel, A. J. Bennett, I. Farrer +3
Single semiconductor quantum dots have been widely studied within devices that can apply an electric field. In the most common system, the low energy offset between the InGaAs quan…
Row coupling in an interacting quasi-one-dimensional quantum wire investigated using transport measurements
L. W. Smith, W. K. Hew, K. J. Thomas +5
We study electron transport in quasi-one-dimensional wires at relatively weak electrostatic confinements, where the Coulomb interaction distorts the ground state, leading to the bi…
Microwave-Driven Transitions in Two Coupled Semiconductor Charge Qubits
K. D. Petersson, C. G. Smith, D. Anderson +3
We have studied interactions between two capacitively coupled GaAs/AlGaAs few-electron double quantum dots. Each double quantum dot defines a tunable two-level system, or qubit, in…
Highly enhanced thermopower in two-dimensional electron systems at milliKelvin temperatures
Srijit Goswami, Christoph Siegert, Matthias Baenninger +4
We report experimental observation of an unexpectedly large thermopower in mesoscopic two-dimensional (2D) electron systems on GaAs/AlGaAs heterostructures at sub-Kelvin temperatur…
Parallel quantized charge pumping
S. J. Wright, M. D. Blumenthal, M. Pepper +4
Two quantized charge pumps are operated in parallel. The total current generated is shown to be far more accurate than the current produced with just one pump operating at a higher…
Nuclear spin coherence in a quantum wire
A. Corcoles, C. J. B. Ford, M. Pepper +3
We have observed millisecond-long coherent evolution of nuclear spins in a quantum wire at 1.2 K. Local, all-electrical manipulation of nuclear spins is achieved by dynamic nuclear…
