Universal Limitations on Quantum Key Distribution over a Network
Siddhartha Das, Stefan Bäuml, Marek Winczewski +1
We consider the distribution of secret keys, both in a bipartite and a multipartite (conference) setting, via a quantum network and establish a framework to obtain bounds on the ac…
Resource theory of entanglement for bipartite quantum channels
Stefan Bäuml, Siddhartha Das, Xin Wang +1
The traditional perspective in quantum resource theories concerns how to use free operations to convert one resourceful quantum state to another one. For example, a fundamental and…
Quantum rebound capacity
Siddhartha Das, Mark M. Wilde
Inspired by the power of abstraction in information theory, we consider quantum rebound protocols as a way of providing a unifying perspective to deal with several information-proc…
Bipartite Quantum Interactions: Entangling and Information Processing Abilities
Siddhartha Das
The aim of this thesis is to advance the theory behind quantum information processing tasks, by deriving fundamental limits on bipartite quantum interactions and dynamics, which co…
