SUMMARY:Progress towards Quantum Error Correction (QEC) on Neutral ato
 m quantum computing.\, Preliminary Exam\, Linipun Phuttitarn
DESCRIPTION:Quantum computers hold the promise of solving problems tha
 t are computationally intractable for classical computers. However\, e
 rrors arising from interactions with the environment and imperfect con
 trol limit their computational power. Quantum error correction (QEC) a
 ddresses this challenge by detecting and correcting errors in logical 
 qubits\, which are encoded across multiple physical qubits. Implementi
 ng QEC\, however\, requires physical qubits with gate fidelities above
  a certain threshold and the ability to perform mid-circuit\, qubit-se
 lective measurements.<br>\n<br>\nIn this talk\, I will present our pro
 gress toward implementing QEC on a neutral-atom quantum processor. Fir
 st\, I will describe a mid-circuit\, qubit-selective measurement schem
 e using a single alkali species that exploits the hyperfine structure.
  Then\, I will discuss a machine learning techniques to enhance qubit 
 readout fidelity. I will also present our work on improving entangling
  gate fidelity using single-photon Rydberg excitation. Finally\, I wil
 l outline our roadmap for achieving the QEC milestone on our processor
 .
