Journal ArticleDOI
Quantum Information with Continuous Variables
TL;DR: In this article, the authors present the Deutsch-Jozsa algorithm for continuous variables, and a deterministic version of it is used for quantum information processing with continuous variables.
Journal ArticleDOI
Statistical distance and the geometry of quantum states
TL;DR: By finding measurements that optimally resolve neighboring quantum states, this work uses statistical distinguishability to define a natural Riemannian metric on the space of quantum-mechanical density operators and to formulate uncertainty principles that are more general and more stringent than standard uncertainty principles.
Journal ArticleDOI
Unconditional quantum teleportation
Akira Furusawa,J. L. Sørensen,Samuel L. Braunstein,Christopher A. Fuchs,H. J. Kimble,Eugene S. Polzik +5 more
TL;DR: The first realization of unconditional quantum teleportation where every state entering the device is actually teleported is realized, using squeezed-state entanglement.
Journal ArticleDOI
Teleportation of Continuous Quantum Variables
TL;DR: In this paper, a protocol for teleportation of a single mode of the electromagnetic field with high fidelity using squeezed-state entanglement and current experimental capability is presented, including the roles of finite quantum correlation and nonideal detection efficiency.
Journal ArticleDOI
Quantum computation over continuous variables
Seth Lloyd,Samuel L. Braunstein +1 more
TL;DR: In this paper, it is shown how a universal quantum computer for the amplitudes of the electromagnetic field can be constructed using simple linear devices, such as beam splitters and phase shifters, together with squeezers and nonlinear devices such as Kerr-effect fibers and atoms in optical cavities.
