Quantum Controls & Hardware-Aware Compilation
I'm an engineering physics student at Embry-Riddle Aeronautical University (BS 2027, MS thesis track 2028). I model Hamiltonians and noise on superconducting qubits, optimize control pulses, and build the compiler infrastructure that connects circuits to hardware. Three preprints on arXiv, all hardware-validated on IQM Garnet.
What I Build
I work across the quantum compilation stack: high-level circuits (OpenQASM 3.0, C++ compiler with DAG IR and SABRE routing), through gate optimization, down to noise-robust control pulses (GRAPE with Lindblad master equation, T₁/T₂ decoherence). The through-line is closing the loop between what algorithms assume and what hardware actually does.
Key Results
- 99.14% gate fidelity via GRAPE optimal control with Lindblad noise modeling (77× error reduction)
- 117× speedup on GPU-accelerated quantum chemistry simulations (VQE on 4× NVIDIA H100)
- 371 circuits analyzed end-to-end from circuit optimization through pulse simulation to hardware execution
- 1,321 tests on QubitOS alone; 2,600+ tests across all projects
- r = -0.74 correlation between pulse duration and infidelity (decoherence dominates gate error budgets)
