Simons Foundation Lectures are free public colloquia related to basic science and mathematics. These high-level talks are intended for professors, students, postdocs and business professionals, but interested people from the metropolitan area are welcome as well.
This talk describes experimental progress toward controlling quantum mechanical coherence and entanglement in a solid-state environment. After describing what coherence and entanglement are, I will explain why using these attributes of the quantum world might be useful for information processing. I will then report from the experimental front lines, describing two approaches to this challenging problem: using electron spin as a quantum bit, and realizing nonabelian excitations in the fractional quantum Hall effect.
