Relaxation, dephasing, and quantum control of electron spins in double quantum dots
J. M. Taylor, J. R. Petta, A. C. Johnson +3
Recent experiments have demonstrated quantum manipulation of two-electron spin states in double quantum dots using electrically controlled exchange interactions. Here, we present a…
Effect of Exchange Interaction on Spin Dephasing in a Double Quantum Dot
E. A. Laird, J. R. Petta, A. C. Johnson +4
We measure singlet-triplet dephasing in a two-electron double quantum dot in the presence of an exchange interaction which can be electrically tuned from much smaller to much large…
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…
Triplet-Singlet Spin Relaxation via Nuclei in a Double Quantum Dot
A. C. Johnson, J. R. Petta, J. M. Taylor +5
The spin of a confined electron, when oriented originally in some direction, will lose memory of that orientation after some time. Physical mechanisms leading to this relaxation of…
Pulsed-gate measurements of the singlet-triplet relaxation time in a two-electron double quantum dot
J. R. Petta, A. C. Johnson, A. Yacoby +3
A pulsed-gate technique with charge sensing is used to measure the singlet-triplet relaxation time for nearly-degenerate spin states in a two-electron double quantum dot. Transitio…
Singlet-triplet spin blockade and charge sensing in a few-electron double quantum dot
A. C. Johnson, J. R. Petta, C. M. Marcus +2
Singlet-triplet spin blockade in a few-electron lateral double quantum dot is investigated using simultaneous transport and charge-sensing measurements. Transport from the (1,1) to…
