# Saturday Physics Series

# Overview

*The Saturday Physics Series consists of five to six scheduled talks. At each talk, adults and high school students meet a University of Colorado professor and learn about his/her research. Talks usually last about one hour. Material is presented at the level of high school juniors and seniors. The series is free, open to the public, and no reservations are required. Simply show up and enjoy the show!*

For more information—or to request a 2014 - 2015 poster—please contact Veronica Lingo.

This project received funding from the CU Outreach Committee.

# 2014 - 2015 Season

**All Lectures are held at 2 p.m. in Duane Physics Room G1B30.**

## “Introduction to Quantum Computation and Quantum Information”Quantum computers and the algorithms that run on them can do everything that classical digital computers can do and, in some cases, provide in addition efficient solutions to problems where no classical algorithm is presently known. Thus, quantum computers appear to provide a model for computation that challenges the mechanical Turing Machine model that held for nearly 50 years. In this overview, we will cover briefly the classical models for computation, and then introduce quantum bits, quantum logic gates, and the quantum circuit model for quantum computation. We will discuss a couple of simple algorithms to illustrate how quantum computation works. The field of quantum computation and quantum information processing is active across the world, with research proceeding at university, government, and increasingly at industrial labs. Prospects for practical quantum computers will be briefly discussed. |

## “How to Hold Many Universes in Your Hand (Sorta)”We live in a world where almost all of the fundamental forces of nature are nearly hidden from us. Only the weakest force—gravity—shows itself to us directly. In most instances, these other forces nearly cancel themselves out, leaving only traces of their nature behind in our daily lives. This means that many of the interactions in the macroscopic universe we live in are the result of only tiny specks of fundamental forces, which come from these very tiny force cancellations. Because of this, small changes in how these cancellations occur can effectively lead to wildly different properties of the universe we live in. In the field of condensed matter physics, we study the interactions that exist inside the materials that surround us and how electrons behave in these systems. By finding materials where the fundamental forces between the electrons and nuclei cancel in slightly different ways, we explore wholly different universes where electrons live. In this talk, I will explain how we use these tiny details to find universes where new laws of physics emerge, where electrons and atoms can move with no friction, where different Higgs bosons or even magnetic monopoles exist, and much more—all in materials you can hold in the palm of your hand. |
