Preliminary Exam
Progress towards Quantum Error Correction (QEC) on Neutral atom quantum computing.
Date: Tuesday, January 13th
Time: 10:30 am - 12:00 pm
Place: Chamberlin Hall Room 5280
Speaker: Linipun Phuttitarn
Abstract: Quantum computers hold the promise of solving problems that are computationally intractable for classical computers. However, errors arising from interactions with the environment and imperfect control limit their computational power. Quantum error correction (QEC) addresses this challenge by detecting and correcting errors in logical qubits, which are encoded across multiple physical qubits. Implementing QEC, however, requires physical qubits with gate fidelities above a certain threshold and the ability to perform mid-circuit, qubit-selective measurements.

In this talk, I will present our progress toward implementing QEC on a neutral-atom quantum processor. First, I will describe a mid-circuit, qubit-selective measurement scheme 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 will outline our roadmap for achieving the QEC milestone on our processor.
