The role of entropy in topological quantum error correction
Michael E. Beverland, Benjamin J. Brown, Michael J. Kastoryano +1
The performance of a quantum error-correction process is determined by the likelihood that a random configuration of errors introduced to the system will lead to the corruption of…
Sample complexity of device-independently certified "quantum supremacy"
Dominik Hangleiter, Martin Kliesch, Jens Eisert +1
Results on the hardness of approximate sampling are seen as important stepping stones towards a convincing demonstration of the superior computational power of quantum devices. The…
Eigenvalue Measurement of Topologically Protected Edge states in Split-Step Quantum Walks
Thomas Nitsche, Tobias Geib, Christoph Stahl +5
We study topological phenomena of quantum walks by implementing a novel protocol that extends the range of accessible properties to the eigenvalues of the walk operator. To this en…
PennyLane: Automatic differentiation of hybrid quantum-classical computations
Ville Bergholm, Josh Izaac, Maria Schuld +65
PennyLane is a Python 3 software framework for differentiable programming of quantum computers. The library provides a unified architecture for near-term quantum computing devices,…
Equation of Motion for Open Quantum Systems incorporating Memory and Initial Correlations
Martin Janßen
An equation of motion for open quantum systems incorporating memory effects and initial correlations with the environment is presented in terms of an effective Liouville operator t…
Quantum walks in external gauge fields
C. Cedzich, T. Geib, A. H. Werner +1
Describing a particle in an external electromagnetic field is a basic task of quantum mechanics. The standard scheme for this is known as "minimal coupling", and consists of replac…
