Notes on super-operator norms induced by Schatten norms

John Watrous

This paper considers basic properties of super-operator norms induced by Schatten p-norms. Such super-operator norms arise in various contexts in the study of quantum information.…

Contractibility of Maximal Ideal Spaces of Certain Algebras of Almost Periodic Functions

A. Brudnyi

We study some topological properties of maximal ideal spaces of certain algebras of almost periodic functions. Our main result is that such spaces are contractible. We present cert…

Magnetic field generation in fully convective rotating spheres

W. Dobler, M. Stix, A. Brandenburg

Magnetohydrodynamic simulations of fully convective, rotating spheres with volume heating near the center and cooling at the surface are presented. The dynamo-generated magnetic fi…

On the hardness of distinguishing mixed-state quantum computations

Bill Rosgen, John Watrous

This paper considers the following problem. Two mixed-state quantum circuits Q and R are given, and the goal is to determine which of two possibilities holds: (i) Q and R act nearl…

Geometric phase for an adiabatically evolving open quantum system

Ingo Kamleitner, James D. Cresser, Barry C. Sanders

We derive an elegant solution for a two-level system evolving adiabatically under the influence of a driving field with a time-dependent phase, which includes open system effects s…

Geometric phase distributions for open quantum systems

K. -P. Marzlin, S. Ghose, B. C. Sanders

In an open system, the geometric phase should be described by a distribution. We show that a geometric phase distribution for open system dynamics is in general ambiguous, but the…
