Quantum computing (QC) offers revolutionary promises of scientific and societal importance, based on its exponential speedup of particular tasks: on the one hand, Peter Shor's algorithm for factoring integers would render RSA encryption obsolete — why QC’s funded; on the other hand, Richard Feynman's quantum simulator would allow us to tackle currently intractable quantum chemistry problems (nitrogen fixation, carbon sequestration) as well as quantum physics ones (high-Tc superconductivity) — why we’re doing, or trying to do, QC.

Significant-loophole-free test of local realism with entangled photons

Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light. Bell’s theorem states that this worldview is incompatible with the predictions of quantum mechanics, as is expressed in Bell’s inequalities. Previous experiments convincingly supported the quantum predictions. Yet, every experiment requires assumptions that provide loopholes for a local realist explanation. Here, we report a Bell test that closes the most significant of these loopholes simultaneously.

Ion Solvation in Room-Temperature Ionic Liquids: Viscosity vs. Ordering

Date:

Due to their structure, ionic liquids exhibit additional levels of ordering beyond those found in common molecular liquids. Polarized 2D IR and pump-probe experiments have been conducted on a molecular anion probe in a series of room-temperature ionic liquids with various cation alkyl chain-lengths. The analysis of these ultrafast experiments characterizes the effects of the growing viscosity and polar-apolar ordering on ion solvation and ionic liquid structure and dynamics

Name Change and Broadened Focus for Optics at Oregon

The Oregen Center for Optical, Molecular and Quantum Science (formerly Oregon Center for Optics) has broadened it's focus and membership. The center seeks to expand beyond optical science into spectroscopy, quantum science and more interdisciplinary optics related research and teaching. The center has added new members in chemistry and physics.

Partial distinguishability, permutation symmetry, and normal modes in multi photon coincidence

This seminar will cover recent work on the analysis of interferometry experiments using partially distinguishable photons.  The analysis simplifies nicely using the permutation group and introducing a ``rate matrix’’.   For a fixed measurement operator this rate matrix does not depend on the input distribution of photons; the rate matrix can be block-diagonalized using permutation group methods only.  The ``normal coordinates’’ associated with this diagonalization have a simple interpretation in terms of unitary group functions and photon states of definite permutation symmetries and partia
