Abstract:
State Preparation is an important preliminary step for many quantum algorithms, such as ground state energy estimation and simulation, however existing methods have high qubit overheads or have difficult to analyze runtimes. We are currently exploring new methods that utilize existing Hamiltonian simulation techniques and properties of random matrices to prepare thermal states of a given Hamiltonian. This talk will cover classical thermal state preparation, followed by an overview of existing quantum techniques, and finally the route we are taking to solving this problem.
