Remote information concentration using a bound entangled state
Mio Murao, Vlatko Vedral
Remote information concentration, the reverse process of quantum telecloning, is presented. In this scheme, quantum information originally from a single qubit, but now distributed…
Proposal for measurment of harmonic oscillator Berry phase in ion traps
I. Fuentes-Guridi, S. Bose, V. Vedral
We propose a scheme for measuring the Berry phase in the vibrational degree of freedom of a trapped ion. Starting from the ion in a vibrational coherent state we show how to revers…
Local Distinguishability of Multipartite Orthogonal Quantum States
Jonathan Walgate, Anthony J. Short, Lucien Hardy +1
We consider one copy of a quantum system prepared in one of two orthogonal pure states, entangled or otherwise, and distributed between any number of parties. We demonstrate that i…
Entangling Atoms and Ions in Dissipative Environments
A. Beige, S. Bose, D. Braun +4
Quantum information processing rests on our ability to manipulate quantum superpositions through coherent unitary transformations, and to establish entanglement between constituent…
Geometric phases for mixed states in interferometry
Erik Sjöqvist, Arun K. Pati, Artur Ekert +4
We provide a physical prescription based on interferometry for introducing the total phase of a mixed state undergoing unitary evolution, which has been an elusive concept in the p…
Fundamental bounds on quantum measurements with a mixed apparatus
S. Bose, V. Vedral
We consider the apparatus in a quantum measurement process to be in a mixed state. We propose a simple upper bound on the probability of correctly distinguishing any number of mixe…
Geometric Quantum Computation
A. Ekert, M. Ericsson, P. Hayden +4
We describe in detail a general strategy for implementing a conditional geometric phase between two spins. Combined with single-spin operations, this simple operation is a universa…
Communication Capacity of Quantum Computation
S. Bose, L. Rallan, V. Vedral
By considering quantum computation as a communication process, we relate its efficiency to a communication capacity. This formalism allows us to rederive lower bounds on the comple…
