Mr. Assaf Halevy Racah Institute of Physics, Hebrew University of Jerusalem Danciger B building, Seminar room Entanglement is perhaps the most intriguing concept of quantum mechanics. It is manifested by non-classical correlations between properties of physical systems that may be separated by space and time, and may not have had any direct interaction. It is not only a useful research tool for studying the foundations of quantum mechanics, but also a key ingredient in quantum information processing (QIP) protocols, that use quantum systems as information carriers. One example of such a protocol is quantum teleportation, in which an unknown state can be destroyed at one location and reconstructed at another, without the transmission of its physical realization. Until now it was thought that only two-state systems can be teleported, since the projection measurement that enables teleportation was proven to be impossible if the required entanglement resource involves only two particles. We suggested and experimentally demonstrated a way in which a three-state system (qutrit) can be teleported, by using four-particle entanglement. This is the first experimentally feasible suggestion for teleporting a state with a finite dimension higher than two. Incorporating such higher-dimensional states in QIP protocols have been proven to enhance their performance. Start: 12:00

Prof. Jonathan Katz Washington University Kaplun building, Room No. 200 It is an attempt to scale models (dimensional only, not detailed) of accretion discs from AGN to X-ray binaries to SGR (not disc geometry, but related physics) to GRB. One conclusion is that a general model of particle acceleration in AGN is not possible because it is very sensitive to even a very small flux of soft photons (i.e., from warm gas) that downscatter energetic electrons: an erg of soft photons is effective in inverse proportion to the square of the photon energy---no hope of ever modeling to that level of detail. Several different regimes in these objects---no simple scaling. Additional details of the upcoming Astrophysics' seminars can be found on the following link. | ||

Prof. Jonathan Katz Washington University Kaplun building, Room No. 200 There has been much talk about the effect of warming on extreme weather events, but these are hard to characterize and almost no one has done anything quantitative. It is the opposite of the issue of the temperature records, where there has been an enormous amount of work. Our work is almost trivial (except for working with corrupted historical data), but the result appears novel, although limited.
