Photonic quantum information: science and technology

Photonic quantum information: science and technology

Recent technological progress in the generation, manipulation and detection of individual single photons has opened a new scientific field of photonic quantum information. This progress includes the realization of single photon switches, photonic quantum circuits with specific functions, and the application of novel photonic states to novel optical metrology beyond the limits of standard optics...

Quantum Information Science and Complex Quantum Systems

My subject in this paper is using quantum information science as an approach to the study of complex quantum systems. The work I describe has involved many collaborators at the University of Queensland and MIT, but I would especially like to emphasize the contribution of Tobias Osborne. Let me begin by asking what it is that makes quantum information science a science? Friends outside the field...

Quantum Information Science and Nanotechnology

In this note is touched upon an application of quantum information science (QIS) in nanotechnology area. The laws of quantum mechanics may be very important for nano-scale objects. A problem with simulating of quantum systems is well known and quantum computer was initially suggested by R. Feynman just as the way to overcome such difficulties. Mathematical methods developed in QIS also may be a...
