Fundamental Limit on the Power of Entanglement Assistance in Quantum Communication Open
The optimal rate of reliable communication over a quantum channel can be enhanced by preshared entanglement. Whereas the enhancement may be unbounded in infinite-dimensional settings even when the input power is constrained, a long-standin…

In this thesis, we are interested in the limits of quantum communication with and without entanglement, and with and without noise assumptions on the communication setup. When a sender and a receiver are connected by a communication line t…

Fully Quantum Arbitrarily Varying Channel Coding for Entanglement-Assisted Communication Open
If a sender and a receiver lack precise knowledge about the communication\nline that connects them, designing a scheme to reliably transmit information\nbecomes more challenging. This has been studied in classical and quantum\ninformation …

Studying Stabilizer de Finetti Theorems and Possible Applications in Quantum Information Processing Open
Symmetries are of fundamental interest in many areas of science. In quantum information theory, if a quantum state is invariant under permutations of its subsystems, it is a well-known and widely used result that its marginal can be approx…

Fault-Tolerant Coding for Entanglement-Assisted Communication Open
Channel capacities quantify the optimal rates of sending information reliably over noisy channels. Usually, the study of capacities assumes that the circuits which the sender and receiver use for encoding and decoding consist of perfectly …
