The SIC question: History and state of play

CA Fuchs, MC Hoang, BC Stacey - Axioms, 2017 - mdpi.com
Recent years have seen significant advances in the study of symmetric informationally
complete (SIC) quantum measurements, also known as maximal sets of complex …

An invitation to quantum incompatibility

T Heinosaari, T Miyadera, M Ziman - Journal of Physics A …, 2016 - iopscience.iop.org
In the context of a physical theory, two devices, A and B, described by the theory are called
incompatible if the theory does not allow the existence of a third device C that would have …

Joint measurability of generalized measurements implies classicality

R Uola, T Moroder, O Gühne - Physical review letters, 2014 - APS
The fact that not all measurements can be carried out simultaneously is a peculiar feature of
quantum mechanics and is responsible for many key phenomena in the theory, such as …

Quantum incompatibility witnesses

C Carmeli, T Heinosaari, A Toigo - Physical review letters, 2019 - APS
We demonstrate that quantum incompatibility can always be detected by means of a state
discrimination task with partial intermediate information. This is done by showing that only …

Incompatibility robustness of quantum measurements: a unified framework

S Designolle, M Farkas, J Kaniewski - New Journal of Physics, 2019 - iopscience.iop.org
In quantum mechanics performing a measurement is an invasive process which generally
disturbs the system. Due to this phenomenon, there exist incompatible quantum …

Comparing the degrees of incompatibility inherent in probabilistic physical theories

P Busch, T Heinosaari, J Schultz… - Europhysics Letters, 2013 - iopscience.iop.org
We introduce a new way of quantifying the degrees of incompatibility of two observables in a
probabilistic physical theory and, based on this, a global measure of the degree of …

Quantifying measurement incompatibility of mutually unbiased bases

S Designolle, P Skrzypczyk, F Fröwis, N Brunner - Physical review letters, 2019 - APS
Quantum measurements based on mutually unbiased bases are commonly used in
quantum information processing, as they are generally viewed as being maximally …

Degree of complementarity determines the nonlocality in quantum mechanics

M Banik, MR Gazi, S Ghosh, G Kar - … Review A—Atomic, Molecular, and Optical …, 2013 - APS
Bohr's complementarity principle is one of the central concepts in quantum mechanics which
restricts joint measurement for certain observables. Of course, later development shows that …

Tight steering inequalities from generalized entropic uncertainty relations

T Kriváchy, F Fröwis, N Brunner - Physical Review A, 2018 - APS
We establish a general connection between entropic uncertainty relations, Einstein-
Podolsky-Rosen steering, and joint measurability. Specifically, we construct steering …

Robustness of incompatibility for quantum devices

E Haapasalo - Journal of Physics A: Mathematical and …, 2015 - iopscience.iop.org
A robustness measure for incompatibility of quantum devices in the lines of the robustness of
entanglement is proposed. The concept of general robustness measures is first introduced …
