Generalised quantum Stein's lemma more robust than ever
Filippo Girardi, Kuan-Yi Lee, Masahito Hayashi +1
The generalised quantum Stein's lemma is a key result in quantum hypothesis testing, and connects this fundamental primitive of quantum information processing with quantum resource…
A General Class of Functionals for Certifying Quantum Incompatibility
Kuan-Yi Lee, Jhen-Dong Lin, Adam Miranowicz +1
Quantum steering, measurement incompatibility, and instrument incompatibility have recently been recognized as unified manifestations of quantum incompatibility. Building on this p…
Resource efficient certification of system environment entanglement solely from reduced system dynamics
Jhen-Dong Lin, Pao-Wen Tu, Kuan-Yi Lee +4
Certifying nonclassical correlations typically requires access to all subsystems, presenting a major challenge in open quantum systems coupled to inaccessible environments. Recent…
Unveiling quantum steering by quantum-classical uncertainty complementarity
Kuan-Yi Lee, Jhen-Dong Lin, Karel Lemr +5
One of the remarkable aspects of quantum steering is its ability to violate local uncertainty complementarity relations. In this vein of study, various steering witnesses have been…
