Semidefinite programming relaxations for quantum correlations
Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

Multi-object operational tasks for measurement incompatibility
AF Ducuara, R Takakura, FJ Hernandez… - arxiv preprint arxiv …, 2024 - arxiv.org
We introduce multi-object operational tasks for measurement incompatibility in the form of
multi-object quantum subchannel discrimination and exclusion games with prior information …

Measurement incompatibility under loss
We investigate the measurement incompatibility of continuous-variable systems with infinite-
dimensional Hilbert spaces under the influence of pure losses, a fundamental noise source …

Covariant correlation-disturbance and its experimental realization with spin-1/2 particles
We formulate a precise tradeoff relation between correlation and disturbance in a sequential
quantum measurement setup. This relation, examined for qubit case, highlights key …
