Please join us Wednesday, April 23, for the next seminar of the PRISM/PCCM Spring ’14 Seminar Series - featuring Prof. Steven M. Girvin. A complete list of seminar speakers is available at: http:www.princeton.edu/prism Speaker: Prof. Steven M. Girvin Yale University Sloane Physics Laboratory Department of Physics Topic : “ Quantum Measurements and Back-Action (Spooky and Otherwise) ” Host : Prof. Hakan E. Tureci, Department of Electrical Engineering Place : Bowen Hall Auditorium Rm. 222 Time : 12:00 PM - 1:00 PM There will be a light lunch for Seminar attendees provided beforehand at 11:30 AM in the Bowen Hall Atrium. Abstract : The topic of measurements and measurement back-action in quantum mechanics was endlessly confusing to the founders of quantum mechanics who were forced to argue in terms of gedanken experiments. Now we must face this confusion because real experiments are happening. This talk will present an introductory tutorial on how real measurements work and how they affect the state of the quantum system under observation. The basic concepts will be illustrated with the Stern-Gerlach experiment and then extended to include dispersive coupling of atoms or qubits to resonant cavities.
