Debbie Leung is a physicist who investigates various aspects of theoretical quantum information processing.
A significant focus of her work involves the quantum information processing capacities of abstract or physical resources, such as the capacity to communicate quantum information using the dual resources of entanglement and quantum/classical channels (remote state preparation and superdense coding of quantum states); the capacity of nonlocal interactions to communicate quantum/classical information; and the capacity to generate entanglement and perform quantum computation.
Leung is also interested in cryptographic applications of quantum information, including composability of important quantum protocols; methods for quantum state encryption and authentication and secure key recycling in such protocols; quantum data hiding; and quantum key distribution. Other work involves variation of measurement-based quantum computation, fault-tolerant quantum computation, and error correcting codes.
Leung’s long-term interests include various quantum or classical correlations in quantum systems, solution state NMR quantum computation and quantum process tomography.
