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
Minimum classical bit for remote preparation and measurement of a qubit
Arun Kumar Pati,Arun Kumar Pati +1 more
TL;DR: In this article, it was shown that a qubit chosen from equatorial or polar great circles on a Bloch sphere can be remotely prepared with one cbit from Alice to Bob if they share one ebit of entanglement.
Journal ArticleDOI
Geometric phases for mixed states in interferometry.
Erik Sjöqvist,Arun Kumar Pati,Arun Kumar Pati,Artur Ekert,Jeeva Anandan,Marie Ericsson,Daniel K. L. Oi,Vlatko Vedral +7 more
TL;DR: This work defines the parallel transport condition that provides a connection form for obtaining the geometric phase for mixed states and reduces to well known formulas in the pure state case when a system undergoes noncyclic and unitary quantum evolution.
Journal ArticleDOI
Perfect teleportation and superdense coding with W states
TL;DR: In this article, it is shown that there is a class of $W$ states that can be used for perfect teleportation and super-dense coding, and that these states can be classified into two categories: GHZ states and W$ states.
Journal ArticleDOI
Stronger uncertainty relations for all incompatible observables.
TL;DR: Two stronger uncertainty relations are given, relating to the sum of variances, whose lower bound is guaranteed to be nontrivial whenever the two observables are incompatible on the state of the system.
