| Abstract: | According to the technique of cavity-QED, using SQUIDs in cavity-QED as the carriers of quantum information, the remote preparations of a single-particle state and a two-particle entangled state are realized, and a generalization to a chosen multi-particle entangled state is also proposed. The research result suggests that the single-particle projective measurements are enough for the success of the remote preparations of the quantum states only with the probability of 1. The experimental feasibility of this scheme is that the cavity field is ultimately in the vacuum state and thus the decoherence of the system is, to some extent, suppressed. |
