    Title: Validation of quantum devices: from quantum random numbers to the D-Wave devices

    Abstract: About a century after the development of quantum mechanics we have now reached an exciting time where non-trivial devices that make use of quantum effects can be built. While a universal quantum computer of non-trivial size is still out of reach there are a number commercial and experimental devices: quantum random number generators, quantum encryption systems, and analog quantum simulators. In this colloquium I will present some of these devices and validation tests we performed on them. Quantum random number generators use the inherent randomness in quantum measurements to produce true random numbers, unlike classical pseudorandom number generators which are inherently deterministic. Optical lattice emulators use ultracold atomic gases in optical lattices to mimic typical models of condensed matter physics. Finally, I will discuss the devices built by Canadian company D-Wave systems, which are special purpose quantum simulators for solving hard classical optimization problems.

    Title: Measurement of Enhanced Confinement at High Pressure Magnetic Cusp System

    Abstract: 56 years ago, Harold Grad and his team at New Your University conjectured (and to some extent calculated) that the confinement properties of a magnetic cusp would be dramatically improved if the confined plasma had sufficiently high pressure to exclude the B-field from the interior. We have carried out an experiment that demonstrates, for the first time, that this effect is real. This has dramatic implications for the future of cusp confined fusion.

    Title: Ultracold Disordered Quantum Gases

    Abstract: Disorder is the rule, rather than the exception, in nature. Despite this, we understand little about how disorder affects interacting quantum matter. I will give an overview of our experiments using ultracold atom gases to probe paradigms of interacting disordered quantum particles. We introduce disorder to naturally clean atomic gases cooled to billionths of a degree above absolute zero using focused optical speckle. I will explain how we observe Anderson localization---a spectacular phenomenon in which interference prevents waves from propagating in a disordered medium---of quantum matter in three dimensions. I will also show how we combine speckle with an optical crystal to emulate a completely tunable and precisely characterized disordered quantum solid. In these optical lattice experiments, we realize disordered Hubbard models that we use to answer critical questions regarding how disorder impacts the properties of electronic solids, such as superconductors and metals.

    Title: Pride and Prejudice in Science and Engineering

    Abstract: During my career I have worked with scientists, engineers, and postdoctoral collaborators, both men and women, from the US and from many foreign countries. In the past ten years, within the context of the Network of the Academies of Sciences (www.iap.org), I have chaired first a global, then a Western Hemisphere initiative (www.ianas.org) addressing the low representation of women in science and technology. Sociologists have produced solid evidence of gender prejudice even within the physical
    sciences that take pride in their objectivity. The IANAS book: “Women Scientists in the Americas; their Inspiring Stories” strikingly illustrates culture-dependent gender prejudice that keeps the physical sciences and engineering preponderantly male occupations in countries such as the US, UK, and Germany. The near-absence of women from engineering, and ignorance about local culture and gender roles adversely affect development work by foreign male engineers serving the poor in the third world. Indeed, both women engineers and social scientists have unique roles to play in overcoming cultural prejudices which waste women’s talents and hamper development work.
