Holonomy for Quantum Channels
David Kult, Johan Åberg, Erik Sjöqvist
A quantum holonomy reflects the curvature of some underlying structure of quantum mechanical systems, such as that associated with quantum states. Here, we extend the notion of hol…

Nodal free geometric phases: Concept and application to geometric quantum computation
Marie Ericsson, David Kult, Erik Sjöqvist +1
Nodal free geometric phases are the eigenvalues of the final member of a parallel transporting family of unitary operators. These phases are gauge invariant, always well-defined, a…

Generalized spectroscopy; coherence, superposition, and loss
Johan Aberg, Daniel K. L. Oi
We analyze single particle coherence and interference in the presence of particle loss and derive an inequality that relates the preservation of coherence, the creation of superpos…
