Distributed quantum information processing - Ujjwal Sen

Quantum information is an emerging science, the results of which, influence many disciplines, ranging through atomic and molecular physics, quantum optics, condensed matter physics, to technology. It predicts spectacular applications like efficient factorization of prime numbers and secure cryptography. For an efficient performance of such tasks, it is important to understand the flow of information distributed over macroscopic or mesoscopic systems, as well as that between separated systems. I will present current research on the quantum mechanical bounds on capacities of communication channels, dynamics of quantum correlations in spin systems, and possibility of fault tolerant quantum computation in quantum neural networks.
