Commuting Heisenberg operators as the quantum response problem: Time-normal averages in the truncated Wigner representation
B. Berg, L. I. Plimak, A. Polkovnikov +3
The applicability of the so-called truncated Wigner approximation (-W) is extended to multitime averages of Heisenberg field operators. This task splits naturally in two. Firstly,…

Qubit protection in nuclear-spin quantum dot memories
Z. Kurucz, M. W. Sørensen, J. M. Taylor +2
We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the sp…
