SUMMARY:Building blocks of an integrated neutral atom quantum network\
 , Thesis Defense\, Preston Huft\, Physics PhD Graduate Student
DESCRIPTION:Despite tremendous progress in quantum information process
 ing towards prototypical devices and early attempts at showing quantum
  utility\, there remain a number of outstanding technical challenges. 
 State of the art quantum computers based on neutral atoms take up subs
 tantial space\, harkening back to the vacuum tube era of classical com
 puting. Reducing the spatial requirements of these machines by transit
 ioning to more integrated architectures is an important goal as these 
 technologies mature. Here we demonstrate two key steps in this directi
 on. First\, a quantum register of Cs single atom qubits is prepared us
 ing a 1225-site optical trap array formed with only passive optics\, r
 emoving the need to use active electro-optic devices for trap pattern 
 formation. The trap pattern is formed using an amplitude mask combined
  with a Fourier filtering setup\, and can be adapted to create dark tr
 aps\, bright traps\, or both interleaved\, using only a single trappin
 g wavelength. Secondly\, we show progress towards a rudimentary two-no
 de quantum network of Rb atoms\, which is a stepping stone towards the
  modularization of quantum processors. The network employs nodes with 
 a novel fiber-coupled design and integrated optics\, reducing the expe
 rimental footprint and leading to superior mechanical stability. We pr
 esent design and construction techniques used for building the nodes a
 s well as initial results with trapped single atoms.
