Quantum computers, although still in their early stages of development, promise unprecedented computing power, unmatched by any conventional technology. This project explores a new path for constructing quantum algorithms: software for a quantum computer. Professor Wang’s approach involves interacting and entangling particles as they go for a quantum walk.

Random walks are an important tool in many areas of science. Likewise quantum walks have shown much potential as a framework for developing excitingly new quantum algorithms. Whereas existing studies predominantly consider single-particle quantum walks, this project aims to explore quantum walks involving two or more particles. Multi-particle quantum walks present a much richer dynamical system due to complex particle interactions and entanglement. Professor Wang aims to utilize these resources to develop novel quantum algorithms with applications in quantum simulations, quantum search, quantum neural networks, and quantum games. She also investigates ways in which one can physically implement multi-particle quantum walk algorithms in the laboratory.
