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…

Quantifying Superposition
Johan Aberg
Measures are introduced to quantify the degree of superposition in mixed states with respect to orthogonal decompositions of the Hilbert space of a quantum system. These superposit…

Operations and single particle interferometry
Johan Aberg
Interferometry of single particles with internal degrees of freedom is investigated. We discuss the interference patterns obtained when an internal state evolution device is insert…
