Limits to error correction in quantum chaos
P. G. Silvestrov, H. Schomerus, C. W. J. Beenakker
We study the correction of errors that have accumulated in an entangled state of spins as a result of unknown local variations in the Zeeman energy (B) and spin-spin interaction en…

Effect of inelastic scattering on the average Coulomb-blockade peak height in quantum dots
C. W. J. Beenakker, H. Schomerus, P. G. Silvestrov
The average height of the Coulomb-blockade conductance peaks for chaotic elastic scattering is known to increase by a factor of 4/3 upon breaking time-reversal symmetry. We calcula…
