SUMMARY:QI/AMO Seminar: "Quantum Computing with Atoms"
CREATED:20090915T130000Z
DESCRIPTION:Both trapped ions and neutral atoms are strong candidate syst
 ems for realizing a scalable quantum computer. This is due to the high d
 egree of control over both the external trapping fields and the internal
  degrees of freedom. Both systems offer the ability to have very strong 
 coupling between qubits and weak coupling to the environment\, but can a
 lso be strongly coupled to the environment through microwave or laser ra
 diation fields for measurement. Trapped ions have shown an unparalleled 
 level of success towards scalable information processing. All of the bas
 ic operations have been implemented with high fidelity and current work 
 is focused on scaling up to higher numbers of qubits. Recently\, neutral
  atoms have made great strides toward scalable quantum information proce
 ssing as well. Neutral atoms in an optical lattice have the advantage of
  a built in scalability\, in that thousands of qubits can be held in reg
 ular micron-sized volume arrays. In this talk\, I will present work done
  in both systems. I will show how all of the basic building blocks have 
 been implemented with trapped ions and present a small quantum algorithm
  performed on two qubits. In addition\, I will presentprogress on a new 
 neutral atom experiment that uses two atomic species in two independent 
 optical lattices for the purpose of quantum computing. One atomic specie
 sacts as a qubit and the second as a messenger atom to mediate and carry
  entanglement among the qubits. Operations are performed between the two
  atomicspecies by translating the lattices with respect to each other to
  bring two target atoms into spatial contact.
