Optimal joint remote state preparation of equatorial states | Xihan Li

12 Aug 2015 | Abstract: | We present a scheme for optimal joint remote state preparation of two-qubit
equatorial states. Our protocol improves on a previous scheme (B. S. Choudhury
and A. Dhara 2015 Quantum Inf. Process. 14 373) that had a success probability
of 25%, which increased to 50% when extra classical information is sent to the
receiver. We show that using our modified scheme, the desired state can be
prepared deterministically with the same quantum channel. Moreover, we
generalize the scheme to prepare N-qubit equatorial states in which the
receiver can reconstruct the original state with 100% success probability. | Source: | arXiv, 1508.2771 | Services: | Forum | Review | PDF | Favorites |
