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…
Characterizations and Quantifications of Macroscopic Quantumness and Its Implementations using Optical Fields
Hyunseok Jeong, Minsu Kang, Hyukjoon Kwon
We present a review and discussions on characterizations and quantifications of macroscopic quantum states as well as their implementations and applications in optical systems. We…
Entangling quantum and classical states of light
Hyunseok Jeong, Alessandro Zavatta, Minsu Kang +5
Entanglement between quantum and classical objects is of special interest in the context of fundamental studies of quantum mechanics and potential applications to quantum informati…
Production of entanglement with highly-mixed states
Minsu Kang, M. S. Kim, Hyunseok Jeong
We study production of entanglement with highly-mixed states. We find that entanglement between highly mixed states can be generated via a direct unitary interaction even when both…
Using macroscopic entanglement to close the detection loophole in Bell inequality
Youngrong Lim, Mauro Paternostro, Jinhyoung Lee +2
We consider a Bell-like inequality performed using various instances of multi-photon entangled states to demonstrate that losses occurring after the unitary transformations used in…
