Quantum communication and fault-tolerance
Paula Belzig
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 se…
Reverse-type Data Processing Inequality
Paula Belzig, Li Gao, Graeme Smith +1
The quantum data processing inequality asserts that two quantum states become harder to distinguish when a noisy channel is applied. On the other hand, a reverse quantum data proce…
Fundamental Limit on the Power of Entanglement Assistance in Quantum Communication
Lasse H. Wolff, Paula Belzig, Matthias Christandl +2
The optimal rate of reliable communication over a quantum channel can be enhanced by pre-shared entanglement. Whereas the enhancement may be unbounded in infinite-dimensional setti…
Fully quantum arbitrarily varying channel coding for entanglement-assisted communication
Paula Belzig
If a sender and a receiver lack precise knowledge about the communication line that connects them, designing a scheme to reliably transmit information becomes more challenging. Thi…
Studying Stabilizer de Finetti Theorems and Possible Applications in Quantum Information Processing
Paula Belzig
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-k…
