Choi representation of completely positive maps in brief
G. Homa, A. Ortega, M. Koniorczyk
The Choi representation of completely positive (CP) maps, i.e. quantum channels is often used in the context of quantum information and computation as it is easy to work with. It i…

Photon number states via iterated photon addition in a loop
Barna Mendei, Gábor Homa, Péter Ãdám +1
We consider the probabilistic generation of time-bin photon number states from a train of single photon pulses. We propose a simple interferometric feedback loop setup having a bea…
