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.
