Areas of Interest

• Quantum Information and Computing

Current Research

Research interests include theoretical aspects of Quantum Error Correction, Quantum Information Theory and Quantum Networks. Currently, we are exploring error mitigaton techniques for near-term (NISQ) devices as well as developing techniques and protocols for building robust, scalable quantum communication networks. We are also working on aspects of quantum information theory that are useful in the study and chaarcterization of quantum many-body systems, such as entanglement growth and operator spreading.
