Oriol Romero-Isart, MPI for Quantum Optics, Germany, Jan.8, 2013 Part I
Oriol Romero-Isart, MPI for Quantum Optics, Germany, lecture during ITAMP/B2 Institute Winter Graduate School on AMO Physics held at the B2 campus in Arizona January 4-11,2013. Quantum mechanics at the limit -- -- Discussion of the motivation of testing quantum mechanics (including the measurement problem, collapse models, the role of gravity in quantum mechanics, side applications, etc.) -- Protocol to prepare large quantum superpositions of massive objects, based on freely expanding the ground-state cooled center-of-mass of a massive object (in a very general framework where the limits on the mass of the object and the superpositions size are only given by unavoidable sources of decoherence.) -- Bounds that this protocol poses to collapse models and comparison to other experiments and proposals. -- Implementation by either optical levitation of dielectric nanospheres in a high-finesse optical cavity or magnetic levitation of superconducting microspheres near a quantum circuit.
