9. The Early History of Quantum Entanglement

Prof. Don Howard (Univ. of Notre Dame, USA)

This talk traces the history of quantum entanglement from Einstein's earliest worries in 1905-at the time of the photon hypothesis paper-about the failure of the mutual independence of quanta outside of the Wien regime, through his early speculations ca. 1909 about wave-particle duality and his first clear and deep insight into the mutual dependence of systems obeying bosonic...

10. Decoherence Measurements in Fullerene Interferometry

We use a near field interferometer of Talbot-Lau type to investigate the wave particle duality of large molecules such as C70 fullerenes. This device is also well suited to study the quantum-to-classical transition via decoherence mechanisms that occur quite naturally in such an interferometer. Interactions of the interfering particle with the surrounding environment lead to a collapse of...

11. EPR correlations in Y(4S) -> B0 anti-B0 decays

Prof. Aurelio Bay (EPFL, Switzerland)

The neutral B-meson pair produced at the Upsilon(4S) should exhibit a non-local correlation of the type discussed by Einstein, Podolski, and Rosen. The time-dependent flavour asymmetry of the B mesons decaying into flavour eigenstates will be used to test such a correlation. The asymmetry obtained from semileptonic B0 decays is in agreement with the prediction from quantum mechanics...
