摘要：
We suggest a procedure of generating entanglement between particles at distant positions such that they cannot be directly entangled via local interaction. An already entangled pair is used to transfer the entanglement to another pair of particles by way of interaction. This scheme of nonlocal generation of entanglement can be used in the construction of a two-qubit universal gate. (c) 2005 Elsevier B.V. All rights reserved.
