Simulation and Analysis of Quantum Circuits
Jobranová, Sára ; Havlena, Vojtěch (oponent) ; Lengál, Ondřej (vedoucí práce)
Simulation of quantum circuits is a key tool for future advancements in the promising field of quantum computing. Due to the fact that this task is very computationally demanding, the performance of state-of-the-art simulators on more complex circuits is still far from satisfactory. In this thesis, we propose a new approach to simulate quantum circuits and present an implementation based on this approach. Our simulation technique allows for accurate simulation and is based on multi-terminal binary decision diagrams. We extended the usual process of a decision diagram-based simulation by symbolic execution of repeating structures in a quantum circuit (such as loops), where we compute the big-step semantics of this structure and do not re-evaluate the gates. We show that symbolic loop execution significantly accelerates the simulation and that the implemented tool is not only competitive with other state-of-the-art simulators, but also greatly outperforms the state of the art for many quantum circuits.
