... It is clear that the advent of quantum computation will significantly change the foundations of modern cryptography. My goal is both to understand how to protect information against quantum adversaries and separately how to take advantage of the counterintuitive properties of quantum mechanics to ac ...

Approach to ergodicity in quantum wave functions
... is possible to absorb Planck's constant into some power of the energy and so to map the semiclassical limit h ! 0 into the more familiar one of increasing energy or increasing quantum numbers. The second alternative applies to general systems with non-scaling Hamiltonians. One then exploits the fact ...

Particle In A Box
... In this chapter, we have studied the particle in a box problem. This is probably the simplest problem in quantum theory and the problem is exactly soluble. The Schrodinger equation for a one dimensional box was obtained by replacing the dynamical variable for the kinetic energy by the corresponding ...
