Abstract: | In this paper a new scheme for teleporting an unknown entangled state of two
particles is proposed. To weaken the requirement for the quantum
channel, without loss of generality, two communicators only share a
non-maximally entangled two-particle state. Teleportation can be
probabilistically realized if sender performs Bell-state
measurements and Hadamard transformation and receiver introduces two
auxiliary particles, operates C-not operation, single-qubit
measurements and appropriate unitary transformations. The
probability of successful teleportation is determined by the smaller
one among the coefficients' absolute values of the quantum
channel. |
