Spin qubit gates via phonon buses in electron nanowires
Dylan Lewis, Roopayan Ghosh, Sanjeev Kumar +4
Scalable architectures for quantum computing using semiconductor quantum dots require interactions between qubits beyond adjacent quantum dots. Here, we propose using nanowires of…
Landau Level Single-Electron Pumping
E. Pyurbeeva, M. D. Blumenthal, J. A. Mol +5
We present the first detailed study of the effect of a strong magnetic field on single-electron pumping in a device utilising a finger-gate split-gate configuration. In the quantum…
Zero-Magnetic Field Fractional Quantum States
S. Kumar, M. Pepper, S. N. Holmes +4
Since the discovery of the Fractional Quantum Hall Effect in 1982 there has been considerable theoretical discussion on the possibility of fractional quantization of conductance in…
Ultrafast Voltage Sampling using Single-Electron Wavepackets
N. Johnson, J. D. Fletcher, D. A. Humphreys +8
We demonstrate an ultrafast voltage sampling technique using a stream of electron wavepackets. Electrons are emitted from a single-electron pump and travel through electron wavegui…
Time-of-Flight Measurements of Single-Electron Wave Packets in Quantum-Hall Edge States
M. Kataoka, N. Johnson, C. Emary +7
We report time-of-flight measurements on electrons travelling in quantum-Hall edge states. Hot-electron wave packets are emitted one per cycle into edge states formed along a deple…
All-electric all-semiconductor spin field effect transistors
Pojen Chuang, Sheng-Chin Ho, L. W. Smith +10
The spin field effect transistor envisioned by Datta and Das opens a gateway to spin information processing. Although the coherent manipulation of electron spins in semiconductors…
