Quantum error correction researcher

Dayeon Yoo

I am a Master's student in Computer Engineering at the University of New Mexico, advised by Prof. Milad Marvian. My research focuses on automated qLDPC code discovery and optimization, including hypergraph product and bivariate bicycle codes.

I develop Python and HPC research pipelines using combinatorial search, low-weight logical-operator analysis, BP+OSD decoding, and Monte Carlo evaluation. My broader interests include neural decoding, logical computation, and hardware-aware quantum error correction. Before moving into QEC, I built production software and data-intensive systems for startups and research teams.

Research

Hardware-aware QEC

Quantum error correction for neutral-atom and trapped-ion architectures.

Experience

Quantum Computing Research Assistant

University of New Mexico

  • Developing computational methods for qLDPC code discovery with Prof. Milad Marvian.
  • Improved reported code distances across four HGP code families and reduced empirical per-run search time by up to 38×.
  • Extending the optimization method to bivariate bicycle codes.

QU-REACH Quantum Computing Research Intern

University of New Mexico

  • Built an adaptive, logical-error-rate-guided search for HGP codes using Tanner graph modifications and BP+OSD decoding.

Data Scientist

University of New Mexico

  • Created a multimodal analysis pipeline combining image, video, audio, and language features to study social-media engagement.

Software Engineer

Divers

  • Led full-stack development of a React Native platform and helped scale the product to more than 15,000 users.
