Nowadays, Information and Communication Technologies (ICT) play increasing central role in the socio-economic, scientific and technological development of our information society. Recently, the peculiar features exhibited by matter at the microscopic (quantum) level, reached by continuous miniaturization, have delivered very interesting advances in many ICT areas, i.e. quantum information science. At this level noise plays an important role, although so far scientists have mainly investigate the impact of uncorrelated noise on quantum ICT (QICT), i.e. noise sources not exhibiting correlations in space and in time. However, investigating the latter will become increasingly pressing with the continuing miniaturization of information processing devices and with higher and higher transmission rates over quantum channels. Here, we will investigate and characterize in a universal framework correlated noise and memory effects in QICTs, which will have a significant impact to realistic optical and solid-state implementations. Particularly, we will deepen a new many-body approach to memory channels (Plenio and Virmani, 2007) and generalize it to bosonic channels, e.g. optical fibers used in long-distance secure quantum communication. Finally, we will propose experimental tests of the expected results, opening up new horizons for realistic QICTs, i.e. fast communications and nanotech processors. This highly original and innovative proposal has the advantage of uniting quantum information theory and condensed matter physics, two very fruitful branches of physics, in which European scientists both on the theoretical as well as on the experimental side are renowned worldwide with Imperial College being a centre of excellence. Under the tutoring of a leading expert in the field (Prof. M. Plenio), it will help the fellow, Dr. F. Caruso, whose previous expertise makes him well-suited for this project, to become a fully independent researcher aspiring to leading academic positions.
