Classical simulation of non-Gaussian bosonic circuits
Beatriz Dias, Robert Koenig
We propose efficient classical algorithms which (strongly) simulate the action of bosonic linear optics circuits applied to superpositions of Gaussian states. Our approach relies o…
How to fault-tolerantly realize any quantum circuit with local operations
Shin Ho Choe, Robert Koenig
We show how to realize a general quantum circuit involving gates between arbitrary pairs of qubits by means of geometrically local quantum operations and efficient classical comput…
Oscillator-to-oscillator codes do not have a threshold
Lisa Hänggli, Robert Koenig
It is known that continuous variable quantum information cannot be protected against naturally occurring noise using Gaussian states and operations only. Noh et al. (PRL 125:080503…
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…
Generalized Log-Majorization and Multivariate Trace Inequalities
Fumio Hiai, Robert Koenig, Marco Tomamichel
We show that recent multivariate generalizations of the Araki-Lieb-Thirring inequality and the Golden-Thompson inequality [Sutter, Berta, and Tomamichel, Comm. Math. Phys. (2016)]…
