About

I am Bingran You, a PhD candidate in Applied Science & Technology at UC Berkeley, advised in the Haeffner Lab.

I build reliable AI systems — agent infrastructure, evaluation harnesses, and applied AI products that need to behave under noisy real-world conditions.

I run trapped-ion quantum experiments — integrated photonics for individual ion addressing, ion-photon interfaces for networking, and 3D-printed micro ion traps for scalable hardware.

Both tracks share one craft: turning complex, noisy systems into something that behaves on purpose.

Focus

AI Builder

  • Agent skills and tool use, with an emphasis on evaluation that mirrors real workflows.
  • Productivity agents that triage notifications, dispatch background work, and stay out of the way.
  • Open-source benchmarks for measuring agent capability and safety in simulated workspaces.

Ion Trapper

  • Adjoint-optimized integrated photonic circuits for individual trapped-ion addressing.
  • Temporally multiplexed ion-photon interfaces via fast ion-chain transport.
  • 3D-printed micro ion trap technology for scalable quantum information processing.
  • Trapped-ion Ramsey interferometry probing causal non-linear quantum mechanics.
