Optimal purification of single qubits

ArXiv quant-ph/9812075 (1998)

Authors:

JI Cirac, AK Ekert, C Macchiavello

Abstract:

We introduce a new decomposition of the multiqubit states of the form $\rho^{\otimes N}$ and employ it to construct the optimal single qubit purification procedure. The same decomposition allows us to study optimal quantum cloning and state estimation of mixed states.
