Thursday, June 14, 2018 Caitlin Jones (PhD student at University of Trieste) ## Micius Satellite and Satellite-to-Ground quantum communicationhe Quantum Experiments at Space Scale (QUESS) is a satellite research project aiming to perform proof-of-concept demonstrations of long-distance quantum communication using a satellite named Micius. |
Tuesday, June 12, 2018 Dr. Marco Oppio (PhD) ## Quantum theory in real or quaternionic Hilbert spaces: how the complex Hilbert space structure emerges from Poincaré symmetryIn principle, the lattice of elementary propositions of a generic quantum system admits a representation in real, complex or quaternionic Hilbert spaces as established by Solèr’s theorem (1995) closin |

Monday, May 21, 2018 Giorgio Torrieri (Researcher, Istituto de Fisica Gleb Wataghin, DRCC, IFGW) ## The Unruh effect, the equivalence principle and quantum field theoryThe idea that the Unruh effect has a role in the apparent thermalization of systems produced in hadronic collisions has gained quite a lot of popularity in the last few years [1]. |
Tuesday, May 15, 2018 Andrea Vinante (Researcher, University of Southampton) ## Experimental test of collapse models and gravity-induced decoherence with mechanical systemsA breakdown of the quantum superposition principle at macroscopic scale, possibly induced by gravity, would allow to solve at the same time the quantum measurement problem and the apparent contradicti |

Thursday, April 12, 2018 José Luis Gaona Reyes (PhD Student, University of Trieste) ## Black Hole Information Loss Paradox and Collapse Models In the first part of the talk, the basic notions of the black hole information loss paradox are presented, following [1]. Then, the proposal of S. K. Modak and D. Sudarsky [2] is described. |
Tuesday, March 27, 2018 Lorenzo Asprea (PhD student, University of Trieste) ## Gravitational DecoherenceOne of the greatest predictions of general relativity is the existence of gravitational waves (GWs), which can be thought of as small perturbations of the metric propagating through spacetime at the |

Tuesday, March 20, 2018 Giulio Gasbarri (Postdoctoral Researcher, University of Trieste) ## On-Chip Quantum Interference of a Superconducting MicrosphereWe propose and analyze an all-magnetic scheme to perform a Young’s double slit experiment with a micron-sized superconducting sphere of mass > ~ 10^13 amu. |
Thursday, February 8, 2018 Antoine Tilloy (Post Doctoral Researcher, Max Planck Institute of Quantum Optics) ## Interacting quantum field theories as relativistic statistical field theories of local beables I will present a generic method to construct collapse models with good symmetry properties starting from interacting quantum field theories. |

Tuesday, February 6, 2018 Antoine Tilloy (Post Doctoral Researcher, Max Planck Institute of Quantum Optics) ## Ghirardi Rimini Weber model with massive flashesHuge amounts of efforts are currently invested in trying to quantize gravity. But are we really sure that gravity should be quantum at the fundamental level? |
Tuesday, August 1, 2017 Luca Curcuraci (Ph.D. student, University of Trieste) ## Stochastic mechanics according to M. NagasawaStochastic mechanics is a attempt to formulate quantum mechanics starting from the theory of stochastic process. The most famous formulation is due to E. Nelson [1]. |
