Interpreting quantum discord through quantum state merging
We present an operational interpretation of quantum discord based on the quantum state merging protocol. Quantum discord is the markup in the cost of quantum communication in the process of quantum state merging, if one discards relevant prior information. Our interpretation has an intuitive explanation based on the strong subadditivity of von Neumann entropy. We use our result to provide opera...
متن کاملRemote transfer of Gaussian quantum discord.
Quantum discord quantifies quantum correlation between quantum systems, which has potential application in quantum information processing. In this paper, we propose a scheme realizing the remote transfer of Gaussian quantum discord, in which another quantum discordant state or an Einstein-Podolsky-Rosen entangled state serves as ancillary state. The calculation shows that two independent optica...
متن کاملRemote state preparation.
Quantum teleportation uses prior entanglement and forward classical communication to transmit one instance of an unknown quantum state. Remote state preparation (RSP) has the same goal, but the sender knows classically what state is to be transmitted. We show that the asymptotic classical communication cost of RSP is one bit per qubit--half that of teleportation--and even less when transmitting...
متن کاملOptimal remote state preparation.
We prove that it is possible to remotely prepare an ensemble of noncommuting mixed states using communication equal to the Holevo information for this ensemble. This remote preparation scheme may be used to convert between different ensembles of mixed states in an asymptotically lossless way, analogous to concentration and dilution for entanglement.
متن کاملLow-entanglement remote state preparation.
An outer bound on the low-entanglement remote state preparation ebits vs bits tradeoff curve [Bennett et al., quant-ph/0006044, 2000] is found using techniques of classical information theory. We show this bound to be optimal among an important class of protocols and conjecture optimality even without this restriction.
