Coherent control of entangled three-atom Rydberg states Neutral atoms make excellent qubits. They interact weakly and are insensitive to environmental perturbations. However, to implement quantum gates one must make them interact. This is usually done by exciting them to high-lying, or Rydberg states. In my group at Kenyon, we are studying new configurations of interacting Rydberg atoms that might find use in building a quantum computer. In this talk, I will give a brief overview of quantum information science. I will then demonstrate how to use lasers to cool atoms to near absolute zero, to protect fragile quantum states. I will explain how Rydberg atoms can interact to form entangled (or correlated) states of three atoms. Finally, I will provide evidence that we can coherently drive these three-atom states, even in the messy environment of a bulk ultracold gas.
