Information Invariance and Quantum Probabilities
Caslav Brukner, Anton Zeilinger
We consider probabilistic theories in which the most elementary system, a two-dimensional system, contains one bit of information. The bit is assumed to be contained in any complet…
State-independent experimental test of quantum contextuality
G. Kirchmair, F. Zähringer, R. Gerritsma +5
The question of whether quantum phenomena can be explained by classical models with hidden variables is the subject of a long lasting debate. In 1964, Bell showed that certain type…
The geometric measure of entanglement for symmetric states
R. Hübener, M. Kleinmann, T. -C. Wei +2
Is the closest product state to a symmetric entangled multiparticle state also symmetric? This question has appeared in the recent literature concerning the geometric measure of en…
Experimental violation of a Bell inequality with two different degrees of freedom of entangled particle pairs
Xiao-song Ma, Angie Qarry, Johannes Kofler +2
We demonstrate hybrid entanglement of photon pairs via the experimental violation of a Bell inequality with two different degrees of freedom (DOF), namely the path (linear momentum…
Cavity-assisted squeezing of a mechanical oscillator
K. Jaehne, C. Genes, K. Hammerer +3
We investigate the creation of squeezed states of a vibrating membrane or a movable mirror in an opto-mechanical system. An optical cavity is driven by squeezed light and couples v…
Observation of strong coupling between a micromechanical resonator and an optical cavity field
Simon Groeblacher, Klemens Hammerer, Michael R. Vanner +1
Achieving coherent quantum control over massive mechanical resonators is a current research goal. Nano- and micromechanical devices can be coupled to a variety of systems, for exam…
