In this talk we will cover recent work from our group on the generation of non-classical light, including photon pairs and triplets, through spontaneous nonlinear parametric processes.  We will discuss specific techniques based on  spontaneous parametric downconversion in nonlinear crystals , as well as on spontaneous four wave mixing in optical fibers for the generation of photon pairs with tailored entanglement properties.   We will also discuss a recent proposal based on third-order spontaneous parametric downconversion in optical fibers for the generation of photon triplets.

Quantum mechanics permits the existence of unique correlations, or entanglement, between individual particles. The ability of entangled particles to act in concert is preserved even when they are separated by large distances and serves as a resource for numerous applications. For example, distributing entangled photon pairs over fiber-optic cables enables secure communication between two remote parties or could offer the possibility of interconnecting quantum computers.

Robots Go Rogue with Girls at the Helm

Saturday, February 12,

Eleven girls came together on Saturday to learn about electric circuits and robotoics.  The workshop hosted by the UO Women in Graduate Science, the Science Factory and the Science Program to Inspire Creativity and Excellence was designed to give girls a chance to get comfortable with electronic components and build their very own "vibrobots."  Read more at the Register-Guard online.

Electronic transport on nanometer dimensions is of fundamental importance in semiconductor nano-electronics. In this talk I will discuss our recent experimental studies of ballistic charge and spin transport on nanometer length scales by using ultrafast nonlinear optical techniques. I will discuss optical injection of ballistic currents through a coherent control technique utilizing quantum interference between one-photon and two-photon absorption pathways.
