Extraction of Pure Entangled States from Many Body Systems by Distant Local Projections
J. Molina-Vilaplana, H. Wichterich, V. E. Korepin +1
We study the feasibility of extracting a pure entangled state of non-complementary, and potentially well separated, regions of a quantum many-body system. It is shown that this can…
Scaling of entanglement between separated blocks in spin chains at criticality
H. Wichterich, J. Molina-Vilaplana, S. Bose
We compute the entanglement between separated blocks in certain spin models showing that at criticality this entanglement is a function of the ratio of the separation to the length…
Exploiting Quench Dynamics in Spin Chains for Distant Entanglement and Quantum Communication
Hannu Wichterich, Sougato Bose
We suggest a method of entangling significantly the distant ends of a spin chain using minimal control. This entanglement between distant individual spins is brought about solely b…
Transport in open spin chains: A Monte Carlo wave-function approach
Mathias Michel, Ortwin Hess, Hannu Wichterich +1
We investigate energy transport in several two-level atom or spin-1/2 models by a direct coupling to heat baths of different temperatures. The analysis is carried out on the basis…
Modeling heat transport through completely positive maps
Hannu Wichterich, Markus J. Henrich, Heinz-Peter Breuer +2
We investigate heat transport in a spin-1/2 Heisenberg chain, coupled locally to independent thermal baths of different temperature. The analysis is carried out within the framewor…
