Pulse Sequences for NMR Quantum Computers: How to Manipulate Nuclear Spins While Freezing the Motion of Coupled Neighbours
N Linden, H Barjat, RJ Carbajo +1
We show how to divide a coupled multi-spin system into a small subset of ``active'' spins that evolve under chemical shift or scalar coupling operators, and a larger subset of ``sp…

Bound Entanglement and Teleportation
N Linden, S Popescu
Recently M. Horodecki, P. Horodecki and R. Horodecki have introduced a set of density matrices of two spin-1 particles from which it is not possible to distill any maximally entang…

Purifying noisy entanglement requires collective measurements
N. Linden, S. Massar, S. Popescu
Known entanglement purification protocols for mixed states use collective measurements on several copies of the state in order to increase the entanglement of some of them. We addr…
