SUMMARY:Utilizing the Quadrupole Transition for Cooling and Imaging of
  Cs Atoms\, Thesis Defense\, Jacob Scott\, Physics PhD Graduate Studen
 t
DESCRIPTION:Neutral atom quantum computing platforms depend on precise
  control and measurement of atomic qubits to realize high-fidelity ope
 rations at scale. This thesis presents a set of experimental and engin
 eering contributions that address critical requirements on laser syste
 ms and light–atom interactions for advancing quantum control of cesi
 um atoms.<br>\n<br>\nIt details the development of low-noise electroni
 c feedback systems for laser frequency locking and magnetic field stab
 ilization\, engineered to support stable and low-noise experimental op
 eration. It further introduces the design\, implementation\, and noise
  characterization of narrow-linewidth laser systems driving Rydberg-le
 vel transitions\, which underpin high-fidelity two-qubit gates via the
  Rydberg blockade mechanism.<br>\n<br>\nThe work also establishes the 
 electric quadrupole transition in cesium as a powerful tool for state-
 selective\, background-free quantum state readout\, achieving a classi
 fication fidelity of 0.9993 and an atom survival probability of 0.995.
  Additionally\, it demonstrates that laser cooling on this transition 
 effectively reduces post-optical pumping atom temperatures to 5.4 uK.<
 br>\n<br>\nCollectively\, these results advance the frontier of robust
 \, high-performance control in cesium-based quantum computing and sign
 ificantly expand the capabilities of neutral atom architectures.
