Joint remote preparation of an arbitrary two-qubit state via a generalized seven-qubit brown state
Qing-Qin Chen, Yan Xia · Laser Physics · 2015
We propose a scheme to realise joint remote preparation of an arbitrary two-qubit state using a generalized seven-qubit brown state as a quantum channel. Generally, the success probability could reach 25% at least in theory. Interestingly, studies show that if the prepared state is a specific two-qubit state, the success probability will be improved up to 100%. We calculate the classical communication cost for the scheme as well.
