Quantum Teleportation of an Arbitrary N-qubit State via EPR Channels

2015

This paper demonstrates that an arbitrary -qubit state can be faithfully and deterministically teleported from Alice to Bob via pairs of EPR channels. The analytical expression of the reconstruct criterion is derived explicitly in the …

Multi-Bit Quantum Private Query

2015 · Communications in Theoretical Physics

Most of the existing Quantum Private Queries (QPQ) protocols provide only single-bit queries service, thus have to be repeated several times when more bits are retrieved. Wei et al.'s scheme for block queries requires a …
