Correcting coherent errors with surface codes
Sergey Bravyi, Matthias Englbrecht, Robert Koenig +1
We study how well topological quantum codes can tolerate coherent noise caused by systematic unitary errors such as unwanted -rotations. Our main result is an efficient algorith…

Coherent state coding approaches the capacity of non-Gaussian bosonic channels
Stefan Huber, Robert Koenig
The additivity problem asks if the use of entanglement can boost the information-carrying capacity of a given channel beyond what is achievable by coding with simple product states…
