Frequency modulated pulses for quantum bits coupled to time-dependent baths
Benedikt Fauseweh, Stefano Pasini, Götz S. Uhrig
We consider the coherent control of a quantum bit by the use of short pulses with finite duration τ_p. By shaping the pulse, we perturbatively decouple the dynamics of the bath fro…
Perfect state transfer in XX chains induced by boundary magnetic fields
Thorben Linneweber, Joachim Stolze, Götz S. Uhrig
A recent numerical study of short chains found near-perfect quantum state transfer between the boundary sites of a spin-1/2 XX chain if a sufficiently strong magnetic field acts on…
Symmetry-Enhanced Performance of Dynamical Decoupling
S. Pasini, G. S. Uhrig
We consider a system with general decoherence and a quadratic dynamical decoupling sequence (QDD) for the coherence control of a qubit coupled to a bath of spins. We investigate th…
