Quantum Information Chapter 10. Quantum Shannon Theory
... My version of Quantum Shannon Theory is no substitute for the more careful treatment in Wilde’s book [1], but it may be more suitable for beginners. This chapter contains occasional references to earlier chapters in my book, but I hope it will be intelligible when read independently of other chapter ...

The Internal and External Problems of String Theory

Thus the philosopher's task, if indeed she has one, is different from what it is when dealing with a more-or-less settled body of theory such as classical Newtonian mechanics, general relativity, or quantum mechanics. In such cases, ...

Even though sodium is a multi-level system, the spectral features and the parameters that govern them are found to be similar to those of the idealized three-level Λ system. For example, in both the idealized model and the actual ...

In the asymmetric 16O16O18O the local-mode states are split by more than 100 cm−1 even at J = 0 (e.g., states 48 vs. 50 of 16O16O18O in Table 1). As values of J ...

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).
