Disturbance-Based Measure of Macroscopic Coherence
Hyukjoon Kwon, Chae-Yeun Park, Kok Chuan Tan +1
We propose a measure of macroscopic coherence based on the degree of disturbance caused by a coarse-grained measurement. Based on our measure, we point out that recently proposed c…
Disappearance of macroscopic superpositions in perfectly isolated systems
Chae-Yeun Park, Hyunseok Jeong
Schrödinger's illustration of an imaginary cat in a box, neither alive nor dead, leads to a question of whether and how long a macroscopic quantum superposition can exist in variou…
A Unified View of Quantum Correlations and Quantum Coherence
Kok Chuan Tan, Hyukjoon Kwon, Chae-Yeun Park +1
In this paper, we argue that quantum coherence in a bipartite system can be contained either locally or in the correlations between the subsystems. The portion of quantum coherence…
