SUMMARY:Atomic dipole traps formed in the diffraction pattern of a cir
 cular aperture for use in neutral atom quantum computing\, Atomic Phys
 ics Seminar\, Katharina Gillen\, California Polytechnic State Universi
 ty
DESCRIPTION:The quantum computing community is making evermore progres
 s towards constructing a fully functional quantum computer. However\, 
 none of the many approaches in the different fields of physics have su
 cceeded to date. In the neutral atom quantum computing approach\, whic
 h uses atoms trapped by light fields as quantum bits (qubits)\, many o
 f the requirements for a quantum computer (initialization\, readout\, 
 single-qubit gates) can be met with well-established spectroscopic tec
 hniques. The recent accomplishment of two-qubit gates with neutral ato
 ms leaves only one unattained criterion for a quantum computer: The ab
 ility to create an addressable array of many qubits.<br>
\n<br>
\nWe w
 ill present computational results on a possible solution to this probl
 em. The diffraction pattern formed by laser light incident on a circul
 ar aperture exhibits localized bright and dark spots that can be used 
 as atomic dipole traps. An array of such apertures results in a two-di
 mensional array of dipole traps that can be individually addressed wit
 h a laser beam from the third dimension. By exploiting the polarizatio
 n dependence of these traps\, we can also bring traps together and apa
 rt to facilitate the performance of two-qubit gates\, thus creating a 
 potential candidate for a scalable quantum memory for a neutral atom q
 uantum computer.<br>
