Quantum control for quantum algorithm design

Presenting Author: Birgitta Whaley, University of California, Berkeley

Optimization is central to the explicit construction of many quantum algorithms. It plays a particularly important role in quantum algorithms characterized by heuristics, such as the Quantum Approximate Optimization Algorithm (QAOA) and hybrid quantum-classical algorithms, such as the variational quantum eigensolver approach to electronic structure calculations. It is also important in development of efficient quantum algorithms for quantum simulations. I shall describe the use of techniques from quantum control and optimization to enable co-design of quantum algorithms, presenting examples of robust design of QAOA protocols and explicit construction of quantum signal processing (QSP) protocols for Hamiltonian simulation and linear algebra.
