Research

QUANTUM COMPUTING

Quantum algorithms are able to provide quantum speedup for several important problems in computer science and mathematics. We design and test new quantum algorithms, expanding the field of quantum computing.

MACHINE LEARNING

We delve into the fundamentals of learning theory, and explore its applications to different interdisciplinary areas of science, including computer graphics and quantum computing.

GRAPH THEORY

Graphs are ubiquitous in nature, and we explore theoretical graph theory and its applications to different areas of science.
