Introduction to Quantum Information
... If we encoded each of the k distinct symbols as a distinct binary number, i.e., as a distinct string of 0’s and 1’s, we would need strings composed of log k bits to represent each symbol (2log k = k). Shannon’s analysis shows that messages produced by a stochastic source can be compressed, in the se ...

Introduction to Quantum Fields in Curved Spacetime
... Before Hawking, spherically symmetric, static black holes were assumed to be completely inert. In fact, it seems more natural that they can decay, since there is no conservation law preventing that. The decay is quantum mechanical, and thermal: Hawking found that a black hole radiates at a temperatu ...

If the energy difference between |kH> and the many neighbour stationary states is very small, the minimal time of the process is very large. For short times we can only determine a certain “state ...

... Our experimental setup is shown schematically in Figure. 3. In a vacuum system, Rubidium atoms are emitted from an oven and form a thermal beam. Two nozzles are used to collimate the atomic beam. The diameter of each nozzle is about 330 µm and the distance between them is about 112 mm. The interacti ...
