Exploring Quantum Average-Case Distances: proofs, properties, and examples
Filip B. Maciejewski, Zbigniew Puchała, Michał Oszmaniec
In this work, we perform an in-depth study of recently introduced average-case quantum distances. The average-case distances approximate the average Total-Variation (TV) distance b…
Operational Quantum Average-Case Distances
Filip B. Maciejewski, Zbigniew Puchała, Michał Oszmaniec
We introduce distance measures between quantum states, measurements, and channels based on their statistical distinguishability in generic experiments. Specifically, we analyze the…
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…
Implementation of quantum measurements using classical resources and only a single ancillary qubit
Tanmay Singal, Filip B. Maciejewski, Michał Oszmaniec
We propose a scheme to implement general quantum measurements, also known as Positive Operator Valued Measures (POVMs) in dimension using only classical resources and a single…
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…
