Distributed quantum computation over noisy channels
(1999)
We analyse the use of entangled states to perform quantum computations non locally among distant nodes in a quantum network. The complexity associated with the generation of multiparticle entangled states is quantified in ...
Entanglement in frequency standards and quantum information theory
(1998)
Entanglement is a key property of quantum information theory. Here we describe ways to quantify the amount of entanglement.We point out the statistical interpretation of these entanglement measures and some connections ...
Improvement of frequency standards with quantum entanglement
(1997)
The optimal precision of frequency measurements in the presence of decoherence is discussed. We analyse different preparations of n two-level systems as well as different measurements procedures. We show that standard ...
