... 2015 as the international year of light. As physicists, this is something many of us use in their daily work, so here was the theme for this year’s meeting. We felt that a focus session on precision measurements and Spectroscopy does fit very well this theme - and a lot of work is done on this topic ...

Quantum Computation: a Tutorial
... quantum computers have been built so far, the laws of quantum physics are mathematically well described. It is therefore possible to try to understand the capabilities of quantum computation, and quantum information turns out to behave substantially differently from usual (classical) information. In ...

Quantum Thermodynamics: A Dynamical Viewpoint
... The prime example of a continuous refrigerator is laser cooling. In this context, it is obtained by reversing the operation of a three-level laser [51,52,66–78]. A quantum absorption refrigerator has also been studied, which is a refrigerator with heat as its power source [53,70,79,80]. An example c ...
