Algorithmic Primitives for Quantum-Assisted Quantum Control
Guru-Vamsi Policharla, Sai Vinjanampathy · Physical Review Letters · 2021
We present two primitive algorithms to evaluate overlaps and transition matrix time series, which are then used to construct several quantum-assisted quantum control algorithms. Unlike previous approaches, our method bypasses tomographically complete measurements and instead relies solely on single qubit measurements. We analyze circuit complexity of composed algorithms and sources of noise arising from Trotterization and measurement errors.
