Bang-Bang refocusing of a qubit exposed to telegraph noise
H. Gutmann, F. K. Wilhelm, W. M. Kaminsky +1
We investigate the decoherence effect of telegraph noise on a single qubit, usually provoked by bistable fluctuators. To diminish the dephasing and relaxation impact an effective r…

Decoherence of the Superconducting Persistent Current Qubit
Lin Tian, L. S. Levitov, Caspar H. van der Wal +5
Decoherence of a solid state based qubit can be caused by coupling to microscopic degrees of freedom in the solid. We lay out a simple theory and use it to estimate decoherence for…
