Embezzlement of entanglement
Speaker(s): Debbie Leung
Abstract: Embezzlement of entanglement is the (impossible) task of producing an entangled state from a product state via a local change of basis, when a suitable catalytic entangled state is available.  The possibility to approximate this task was first observed by van Dam and Hayden in 2002.&nbs... read more

The quantum and private capacities of quantum channels, and the solution in the low-noise regime
Speaker(s): Debbie Leung
Abstract: We first summarize background on the quantum capacity of a quantum channel, and explain why we know very little about this fundamental quantity, even for the qubit depolarizing channel (the quantum analogue of the binary symmetric channel) despite 20 years of effort by the community. Then, we foc... read more

Maximal Privacy Without Coherence
Speaker(s): Debbie Leung
Abstract: Privacy and coherence have long been considered closely related properties of a quantum state. Indeed, a coherently transmitted quantum state is inherently private. Surprisingly, coherent quantum communication is not always required for privacy: there are quantum channels that are too noisy to trans... read more

Quantum network coding, entanglement, and graphs.
Speaker(s): Debbie Leung
Abstract: In arXiv:quant-ph/0608223, quantum network coding was proved to be no more useful than simply routing the quantum transmissions in some directed acyclic networks. This talk will connect this result, monogamity of entanglement, and graph theoretic properties of the networks involved.
