Semidefinite programming relaxations for quantum correlations

A Tavakoli, A Pozas-Kerstjens, P Brown… - Reviews of Modern Physics, 2024 - APS
Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

Catalysis in quantum information theory

P Lipka-Bartosik, H Wilming, NHY Ng - Reviews of Modern Physics, 2024 - APS
Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

Compatibility of generalized noisy qubit measurements

MJ Renner - Physical Review Letters, 2024 - APS
It is a crucial feature of quantum mechanics that not all measurements are compatible with
each other. However, if measurements suffer from noise they may lose their incompatibility …

Exact steering bound for two-qubit Werner states

Y Zhang, E Chitambar - Physical review letters, 2024 - APS
Whether positive operator-valued measures (POVMs) provide advantages in demonstrating
Bell nonlocality has remained unknown, even in the simple scenario of Einstein-Podolsky …

Experimental demonstration of a Maxwell's demon quantum battery in a superconducting noisy intermediate-scale quantum processor

J Yu, S Wang, K Liu, C Zha, Y Wu, F Chen, Y Ye, S Li… - Physical Review A, 2024 - APS
Entering the era of post-quantum supremacy has given one the ability to precisely control
noisy intermediate-scale quantum (NISQ) processors with multiqubits and extract valuable …

Dynamical resource theory of incompatibility preservability

CY Hsieh, B Stratton, CH Wu, HY Ku - Physical Review A, 2025 - APS
The uncertainty principle is one of quantum theory's most foundational features. It underpins
a quantum phenomenon called measurement incompatibility—two physical observables of …
