Quench Induced Growth of Distant Entanglement from Product and Locally Entangled States in Spin Chains
Bedoor Alkurtass, Hannu Wichterich, Sougato Bose
We study the problem of entangling two spins at the distant ends of a spin chain by exploiting the nonequilibrium dynamics of the system after a sudden global quench. As initial st…
Universality of the negativity in the Lipkin-Meshkov-Glick model
H. Wichterich, J. Vidal, S. Bose
The entanglement between noncomplementary blocks of a many-body system, where a part of the system forms an ignored environment, is a largely untouched problem without analytic res…
Density dynamics from current auto-correlations at finite time- and length-scales
Robin Steinigeweg, Hannu Wichterich, Jochen Gemmer
We consider the increase of the spatial variance of some inhomogeneous, non-equilibrium density (particles, energy, etc.) in a periodic quantum system of condensed matter-type. Thi…
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…
