About me

Portrait of Kevin J. Joven

I’m a Ph.D. student in Electrical and Computer Engineering at NC State University, developing quantum applications for chemistry and physics. My current toolset: quantum signal processing (QSP), block encodings, benchmarking, and hardware execution on superconducting and trapped-ion devices. Now I’m eagerly implementing AI tools to discover new algorithms for applications.

Open profile

Experience

Jun to Aug 2026

Quantum Benchmarking Summer Intern

SRI International

  • Full-time summer internship at SRI International in the United States.
  • Benchmarking dynamic circuits. Implemented genetic dynamical decoupling sequences to benchmark dynamic circuits on superconducting architectures. Paper in preparation.
May to Oct 2024

Research intern, PHI Lab

NTT Research

  • Quantum chaos in electronic structure. Mentored by Dr. Victor M. Bastidas, studied out-of-time-order correlators of the H4 molecule across equilibrium and far-from-equilibrium geometries.
  • Complexification of QSP. Exchanging space and time in the circuit gives a generalized QSP sequence with a complex-valued signal.
