Title: Transfer of d-level quantum states through spin chains by random swapping

Abstract

We generalize an already proposed protocol for quantum state transfer to spin chains of arbitrary spin. An arbitrary unknown d-level state is transferred through a chain with rather good fidelity by the natural dynamics of the chain. We compare the performance of this protocol for various values of d. A by-product of our study is a much simpler method for picking up the state at the destination as compared with the one proposed previously. We also discuss entanglement distribution through such chains and show that the quality of entanglement transition increases with the number of levels d.

  • We examine the role that interference plays in quantum state transfer through several types of finite spin chains, including chains with isotropic Heisenberg interaction between nearest neighbors, chains with reduced coupling constants to the spins at the end of the chain, and chains with anisotropic coupling constants. We evaluate quantitatively both the interference corresponding to the propagation of the entire chain and the interference in the effective propagation of the first and last spins only, treating the rest of the chain as a black box. We show that perfect quantum state transfer is possible without quantum interference and provide evidencemore » that the spin chains examined realize interference-free quantum state transfer to a good approximation.« less
  • Transmitting quantum states and entanglement through quantum channels is one of the key requirements for the development of quantum computation. Quantum discord has received much attention in quantum computation. We transfer quantum discord through two parallel XXZ spin chains with phase shift. The maximum discord can be enhanced by the phase shift. It will take more time to obtain an enhanced maximum discord in some cases, but for other cases, both the maximum and speed are enhanced by the phase shift. In the thermodynamic limit, the effect of the phase shift disappears and the maximum discord exponentially decays with increasingmore » of the receiving position. Our results on spin chains are generalized to a family of linear Hamiltonians.« less
  • In combination with the theories of open system and quantum recovering measurement, we propose a quantum state transfer scheme using spin chains by performing two sequential operations: a projective measurement on the spins of ‘environment’ followed by suitably designed quantum recovering measurements on the spins of interest. The scheme allows perfect transfer of arbitrary multispin states through multiple parallel spin chains with finite probability. Our scheme is universal in the sense that it is state-independent and applicable to any model possessing spin–spin interactions. We also present possible methods to implement the required measurements taking into account the current experimental technologies.more » As applications, we consider two typical models for which the probabilities of perfect state transfer are found to be reasonably high at optimally chosen moments during the time evolution. - Highlights: • Scheme that can achieve perfect quantum state transfer is devised. • The scheme is state-independent and applicable to any spin-interaction models. • The scheme allows perfect transfer of arbitrary multispin states. • Applications to two typical models are considered in detail.« less
  • The effect of disorder on the quantum phase transitions induced by a transverse field, anisotropy, and dimerization in {ital XY} spin chains is investigated. The low-energy behavior near the critical point is described by a Dirac-type equation for which an exact analytic treatment is possible. Results obtained for the dynamical critical exponent, the specific heat, and the transverse susceptibility agree with results recently obtained using a real space renormalization group decimation technique. A nonzero transverse field changes the universality class of the anisotropy transition. {copyright} {ital 1996 The American Physical Society.}
