Charge and spin manipulation in a few-electron double dot
J. R. Petta, A. C. Johnson, J. M. Taylor +5
We demonstrate high speed manipulation of a few-electron double quantum dot. In the one-electron regime, the double dot forms a charge qubit. Microwaves are used drive transitions…
Gate-Defined Quantum Dots on Carbon Nanotubes
M. J. Biercuk, S. Garaj, N. Mason +2
We report the realization of nanotube-based quantum dot structures that use local electrostatic gating to produce individually controllable dots in series along a nanotube. Electro…
Zero-field splitting of Kondo resonances in a carbon nanotube quantum dot
J. Nygard, W. F. Koehl, N. Mason +2
We present low-temperature electron transport measurements on a single-wall carbon nanotube quantum dot exhibiting Kondo resonances at low temperature. Contrary to the usual behavi…
Controlling Spin Qubits in Quantum Dots
Hans-Andreas Engel, L. P. Kouwenhoven, Daniel Loss +1
We review progress on the spintronics proposal for quantum computing where the quantum bits (qubits) are implemented with electron spins. We calculate the exchange interaction of c…
Anomalous Conductance Quantization in Carbon Nanotubes
M. J. Biercuk, N. Mason, J. Martin +2
Conductance measurements of carbon nanotubes containing gated local depletion regions exhibit plateaus as a function of gate voltage, spaced by approximately e2/h, the quantum of c…
Locally addressable tunnel barriers within a carbon nanotube
M. J. Biercuk, N. Mason, J. M. Chow +1
We report the realization and characterization of independently controllable tunnel barriers within a carbon nanotube. The nanotubes are mechanically bent or kinked using an atomic…
