Convex conservation of von Neumann entropy implies unitarity or antiunitarity
Nicolas G. Underwood, Jonte R. Hance
On the space of density matrices , Kadison's theorem establishes that all invertible convex transformations are unitarity or antiunitary. For a finite Hilber…

A principle of information conservation for physical laws (Hidden information in quantum systems?)
Nicolas Underwood
A principle of information conservation is shown in abstract terms to rule out probabilistic physical laws, necessitating the existence of state trajectories. It furthermore provid…

Signatures of relic quantum nonequilibrium
Nicolas G. Underwood
[Shortened Abstract:] This thesis explores the possibility that quantum probabilities arose thermodynamically. A chief concern is the detection of primordial `quantum nonequilibriu…
