Quantum macroscopicity measure for arbitrary spin systems and its application to quantum phase transitions
Chae-Yeun Park, Minsu Kang, Chang-Woo Lee +3
We explore a previously unknown connection between two important problems in physics, i.e., quantum macroscopicity and the quantum phase transition. We devise a general and computa…

Is macroscopic entanglement a typical trait of many-particle quantum states?
Malte C. Tichy, Chae-Yeun Park, Minsu Kang +2
We elucidate the relationship between Schrödinger-cat-like macroscopicity and geometric entanglement, and argue that these quantities are not interchangeable. While both properties…

Bell inequality tests using asymmetric entangled coherent states in asymmetric lossy environments
Chae-Yeun Park, Hyunseok Jeong
We study an asymmetric form of two-mode entangled coherent state (ECS), where the two local amplitudes have different values, for testing the Bell-Clauser-Horne-Shimony-Holt (Bell-…
