Measuring relational information between quantum states, and applications
Michał Oszmaniec, Daniel J. Brod, Ernesto F. Galvão
The geometrical arrangement of a set of quantum states can be completely characterized using relational information only. This information is encoded in the pairwise state overlaps…
Modeling and mitigation of cross-talk effects in readout noise with applications to the Quantum Approximate Optimization Algorithm
Filip B. Maciejewski, Flavio Baccari, Zoltán Zimborás +1
We introduce a correlated measurement noise model that can be efficiently described and characterized, and which admits effective noise-mitigation on the level of marginal probabil…
A universal scheme for robust self-testing in the prepare-and-measure scenario
Nikolai Miklin, Michał Oszmaniec
We consider the problem of certification of arbitrary ensembles of pure states and projective measurements solely from the experimental statistics in the prepare-and-measure scenar…
Mitigation of readout noise in near-term quantum devices by classical post-processing based on detector tomography
Filip B. Maciejewski, Zoltán Zimborás, Michał Oszmaniec
We propose a simple scheme to reduce readout errors in experiments on quantum systems with finite number of measurement outcomes. Our method relies on performing classical post-pro…
Classical simulation of linear optics subject to nonuniform losses
Daniel Jost Brod, Michał Oszmaniec
We present a comprehensive study of the impact of non-uniform, i.e.\ path-dependent, photonic losses on the computational complexity of linear-optical processes. Our main result st…
Operational relevance of resource theories of quantum measurements
Michał Oszmaniec, Tanmoy Biswas
For any resource theory it is essential to identify tasks for which resource objects offer advantage over free objects. We show that this identification can always be accomplished…
