Research Interests

General research interests include fundamentals of quantum information sciences. Specific interests are finding performance limits, e.g., channel capacity of quantum communication channels and/or applying quantum computing algorithms to the problems of practical interest in communication systems. To this end, I utilize tools from quantum information theory, probability theory, machine learning, linear algebra, and complexity theory.
