Resource-efficient entanglement detection in high-dimensional states via two-qubit witnesses
Josef Kadlec, Artur BarasiÅski, Karel Lemr
This paper presents an efficient method for detecting entanglement in high-dimensional two-qudit states by mapping the Hilbert space onto the space of two qubits. This transformati…

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…
