A straightforward introduction to continuous quantum measurement
... In feedback control a system is continuously measured, and this information is used while the measurement proceeds (that is, in real time) to modify the system Hamiltonian so as to obtain some desired behaviour. Thus, continuous measurement theory is essential for describing feedback control. The in ...

Limits on Efficient Computation in the Physical World
... More than a speculative technology, quantum computing seems to challenge our most basic intuitions about how the physical world should behave. In this thesis I show that, while some intuitions from classical computer science must be jettisoned in the light of modern physics, many others emerge nearl ...

... In the first chapter, Mechanics, we present the often overemphasized Newtonian approach to mechanics next to the Lagrange and Hamilton formulations. Each of these equivalent representations distinguishes itself by specific advantages: whereas Newton’s approach is most easily accessible using the conce ...

Gauge Theories of the Strong and Electroweak Interactions

In quantum mechanics the dichotomy between particles and fields is upheld, although the wave-particle dua ...
