Chapter 1
... In classical mechanics we have separate equations for wave motion and particle motion, whereas in quantum mechanics, in which the distinction between particles and waves is not clear-cut, we have a single equation—the Schr¨odinger equation. We have seen that the link between the Schrödinger equation ...

Silicon quantum dots for quantum information processing
... Electrons occupy different quantum dots when representing different logics, hence one can measure electron charge instead of spin, this is called spin-charge conversion. Double Quantum Dot (DQD) double reservoir system allows us to measure current directly, current resonate when quantum dot energy c ...

The physical nature of information
... When we first learned to count on our very classical and sticky little fingers we were misled into thinking about information as a classical entity. In the binary case that that requires either a 0 or I state. But nature allows a quantum mechanically coherent superposition of 0 and 1. That is a degr ...

CALCULATING A MAXIMIZER FOR QUANTUM MUTUAL
... in a state that has been sent over a noisy quantum channel. The capacity of a channel is given by the maximization of this Holevo quantity over an ensemble of input states, and can be interpreted as the amount of information that can be sent reliably over the channel. We focus on obtaining the maxim ...

What is the correct framework for Quantum Field Theories?
... things in the quantum electrodynamics or its extension, the Standard Model. But they are both rather mundane from a more modern point of view of quantum field theories. After all, although experimentally verified only a few years ago, the Standard Model was theoretically established in the early 70s. ...

Thermal effects on sudden changes and freezing
... the sudden change of the QD to different initial conditions. In this context, the present work shed more light on this important subject. In particular, for the system under study, we find that the atomic density matrix preserves the initial BD form only for a short time under the action of the heat ...
