Detecting entanglement with non-hermitian operators
Mark Hillery, Ho Trung Dung, Julien Niset
We derive several entanglement conditions employing non-hermitian operators. We start with two conditions that were derived previously for field mode operators, and use them to der…
Searching via walking: How to find a marked subgraph of a graph using quantum walks
Mark Hillery, Daniel Reitzner, Vladimir Buzek
We show how a quantum walk can be used to find a marked edge or a marked complete subgraph of a complete graph. We employ a version of a quantum walk, the scattering walk, which le…
Quantum Machines
Mark Hillery, Vladimir Buzek
We discuss quantum information processing machines. We start with single purpose machines that either redistribute quantum information or identify quantum states. We then move on t…
An Introduction to the Quantum Theory of Nonlinear Optics
Mark Hillery
This article is provides an introduction to the quantum theory of optics in nonlinear dielectric media. We begin with a short summary of the classical theory of nonlinear optics, t…
Unambiguous identification of coherent states II: Multiple resources
Michal Sedlak, Mario Ziman, Vladimir Buzek +1
We consider unambiguous identification of coherent states of electromagnetic field. In particular, we study possible generalizations of an optical setup proposed in M. Sedlák {\it…
