Localizing entanglement between spins is possible via local measurements. Classical correlations set lower bounds for this entanglement, with the Ising model showing quantum phase transition features.

Area of Science:

  • Quantum Information Science
  • Condensed Matter Physics

Background:

  • Entanglement is a key quantum resource for computation and communication.
  • Understanding how entanglement behaves in many-body systems is crucial.

Purpose of the Study:

  • To investigate the localizable entanglement between two spins in a large quantum system.
  • To establish bounds for localizable entanglement using classical correlations.
  • To analyze entanglement properties in the Ising spin model.

Main Methods:

  • Studying pure quantum states of N>>1 spins or qubits.
  • Performing local measurements on individual spins.
  • Analyzing classical correlation functions.
  • Examining the Ising spin model.

Main Results:

  • Classical correlation functions provide lower bounds for localizable entanglement.
  • Local measurements can increase classical correlations.
  • Characteristic features of quantum phase transitions, like diverging entanglement length, were observed in the Ising model.

Conclusions:

  • Localizable entanglement can be bounded by classical correlations.
  • The Ising spin model exhibits quantum phase transition phenomena related to entanglement length.
