Driving non-Gaussian to Gaussian states with linear optics
D. E. Browne, J. Eisert, S. Scheel +1
We introduce a protocol that maps finite-dimensional pure input states onto approximately Gaussian states in an iterative procedure. This protocol can be used to distill highly ent…
Non-classical Gaussian states in noisy environments
Stefan Scheel, Dirk-Gunnar Welsch
In this article we review properties of Gaussian states and describe operations on them. The interaction of the electromagnetic field with an absorbing dielectric as a special type…
Single photons on demand from 3D photonic band-gap structures
Marian Florescu, Stefan Scheel, Hartmut Haeffner +4
We describe a practical implementation of a (semi-deterministic) photon gun based on stimulated Raman adiabatic passage pumping and the strong enhancement of the photonic density o…
On the impossibility of distilling Gaussian states with Gaussian operations
J. Eisert, S. Scheel, M. B. Plenio
We show that no distillation protocol for Gaussian quantum states exists that relies on (i) arbitrary local unitary operations that preserve the Gaussian character of the state and…
