Optimal purification of single qubits
J. I. Cirac, A. K. Ekert, C. Macchiavello
We introduce a new decomposition of the multiqubit states of the form and employ it to construct the optimal single qubit purification procedure. The same decomposi…

Distributed Quantum Computation over Noisy Channels
J. I. Cirac, A. Ekert, S. F. Huelga +1
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 multip…
