Topic: Quantum finite automata and their simulations
PresentationAbstract:
Finite automata are real models of computers, which have only limited amount of memory. They have been proposed more than sixty years ago. Since then they been quite well recognized and approached from various perspectives, including algebra and logics. The picture for the theory of quantum automata and languages generated by them is less clear, and various important problems remain open [1].
This talk will present different types of Quantum Finite Automata, their modes of work, relations between them and hierarchy of languages they generate [2]. Next, the talk will present a library [3] to simulate different kinds of quantum finite automata on a classical computer and will show experiments measuring time complexity of the simulation. Examples of library usage will also be demonstrated. Finally, possible directions of development will be indicated.
