AMO/IQSE seminar: Time-inversion in quantum metrology
Speaker: Luiz Davidovich (Institute for Quantum Science and Engineering, Texas A&M University; Hagler Institute for Advanced Study; Federal University of Rio de Janeiro)
Quantum metrology aims to estimate parameters, like weak electric and magnetic fields, temperature, phases, small displacements, and the time duration of a dynamical process, with precision beyond that attained by classical metrological methods. The usual procedure involves measuring a probe, prepared in a convenient initial state, after it has interacted [...]
AMO/IQSE seminar: Time and Quantum Gravity
Speaker: William G. Unruh (Canadian Institute for Advanced Research; University of British Columbia; Institute for Quantum Science and Engineering, Texas A&M University; Hagler Institute for Advanced Study )
The very different roles that time plays in Quantum Mechanics and in Gravity seems to be one of the main impediments to developing a quantum theory of gravity. I will review these and the problems they cause each other. Unfortunately I will not give a solution.
