Exponential error rates in multiple state discrimination on a quantum spin chain
Exponential error rates multiple state discrimination quantum spin chain
2015/8/25
We consider decision problems on finite sets of hypotheses represented by pairwise different shift-invariant states on a quantum spin chain. The decision in favor of one of the hypotheses is based on ...
Permutation operators, entanglement entropy, and the XXZ spin chain in the limit Δ-> -1
Permutation operators entanglement entropy the XXZ spin chain
2010/12/24
In this paper we develop a new approach to the investigation of the bi-partite entanglement entropy in integrable quantum spin chains. Our method employs the well-known replica trick, thus taking a re...
Prefect Transfer of Quantum States on Spin Chain with Dzyaloshinskii- Moriya interaction in inhomogeneous Magnetic field
XY Spin-Chain Teleportation Dzyaloshinskii-Moriya interaction
2010/10/29
In this work, we use the Hamiltonian of a modified Dzyaloshinskii-Moriya model and investigate the perfect transfer of the quantum state on the spin networks. In this paper, we calculate fidelity in w...

We consider an infinite one dimensional anisotropic XY spin chain with a nearest neighbor time-
dependent Heisenberg coupling J(t) between the spins in presence of a time-dependent magnetic

Jordanian deformation of the open XXX-spin chain
open XXX-spin chain invariant Yang R-matrix

The general solution to the reflection equation associated with the jordanian deformation of the SL(2) invariant Yang R-matrix is found. The same K-matrix is obtained by the special scaling limit of t...
