Emergence of pointer states in a non-perturbative environment

Marc Busse, Klaus Hornberger

We show that the pointer basis distinguished by collisional decoherence consists of exponentially localized, solitonic wave packets. Based on the orthogonal unraveling of the quant…

Theory and experimental verification of Kapitza-Dirac-Talbot-Lau interferometry

Klaus Hornberger, Stefan Gerlich, Hendrik Ulbricht +5

Kapitza-Dirac-Talbot-Lau interferometry (KDTLI) has recently been established for demonstrating the quantum wave nature of large molecules. A phase space treatment permits us to de…

Practical methods for witnessing genuine multi-qubit entanglement in the vicinity of symmetric states

Geza Toth, Witlef Wieczorek, Roland Krischek +3

We present general numerical methods to construct witness operators for entanglement detection and estimation of the fidelity. Our methods are applied to detecting entanglement in…

Experimental entanglement of a six-photon symmetric Dicke state

Witlef Wieczorek, Roland Krischek, Nikolai Kiesel +3

We report on the experimental observation and characterization of a six-photon entangled Dicke state. We obtain a fidelity as high as 0.6540.024 and prove genuine six-photon e…

Multi-qubit entanglement engineering via projective measurements

Witlef Wieczorek, Nikolai Kiesel, Christian Schmid +1

So far, various multi-photon entangled states have been observed experimentally by using different experimental set-ups. Here, we present a scheme to realize many SLOCC-inequivalen…

Non-classical correlations from dissociation time entanglement

Clemens Gneiting, Klaus Hornberger

We discuss a strongly entangled two-particle state of motion that emerges naturally from the double-pulse dissociation of a diatomic molecule. This state, which may be called disso…
