Quantum Shannon theory extends classical information theory to the quantum regime, establishing fundamental limits for communication, compression, and information processing when quantum effects such as entanglement and superposition are available.

My research program has made foundational contributions to quantum Shannon theory, from establishing entanglement-assisted channel capacities to developing quantum rate-distortion theory and one-shot information theory. This work provides the theoretical bedrock for understanding what is possible—and what is impossible—in quantum communication and computation.

Our contributions include multi-user quantum communication scenarios (multiple-access channels, broadcast channels), source-channel separation theorems, reverse Shannon theorems, and non-asymptotic characterizations that bridge theory with practical finite-blocklength implementations. These results have been published in leading venues including IEEE Transactions on Information Theory, Physical Review journals, and top theory conferences.
