Abstract

Basing on the scheme without the state vector collapse postulation for quantum teleporting and unknown one particle state that proposed by Busch et al,a new scheme for quantum teleporting an unknown two particle state of general formation has been investigated .

Zhang Ping, Yan Feng-Li

Based the scheme without the collapse postulation for quantum teleporting that proposed by Busch et al,a scheme for quantum teleporting of a four-particle state of general formation is proposed,which takes into account the action of the measuring device and avoids any reference to the postulation of the state vector collapse.

Quantum teleportation of an unknown two-level two-particle entangled state

Ling Yun Hao

Based on the standard teleportation scheme and the controlled teleportation scheme for an unknown quantum state of a single two-level particle,it was generalized the discussion to two-particle cases and performed a detailed calculation for the two particle problem.It was discussed briefly the problem of transportation of any unknown quantum state of arbitrary number of two-level particles also.

Probabilistic Teleportation of Two—Particle State of General Formation

YANFeng-Li, TANHong-Ge

A scheme for probabilistic teleporting an unknown two-particle state of general formation by partly pure entangled four-particle state is proposed. It is shown that after performing two Bell state measurements, proper unitary transformation and the measurement on an auxiliary qubit, the unknown two-particle state of general formation, which was destroyed at one place, can be reconstructed at another place with certain probability.

Multiparticle Generalization of Teleportation

Chui‐Ping Yang, Guang‐Can Guo

A scheme for teleporting an unknown quantum state of many particles is proposed. The scheme operates essentially by prearranging the sharing of an Einstein-Podolsky-Rosen-correlated pair of particles every time. We show that after performing a series of Bell-state measurements and single-particle unitary transformations, the unknown state of many particles, which was destroyed at one place, can be reconstructed at another place. Our scheme is actually obtained by generalizing an earlier scheme of Bennett et al. [ Phys. Rev. Lett. 70 (1993) 1895 ; 76 (1996) 722 ] known as quantum teleportation to the multiparticle case.
