On dynamical stability of composite quantum particles: when entanglement is enough and when interaction is needed
Zakarya Lasmar, Adam S. Sajna, Su-Yong Lee +1
We consider an evolution of two elementary quantum particles and ask the question: under what conditions such a system behaves as a single object? It is obvious that if the attract…
Optimal Gaussian measurements for phase estimation in single-mode Gaussian metrology
Changhun Oh, Changhyoup Lee, Carsten Rockstuhl +4
The central issue in quantum parameter estimation is to find out the optimal measurement setup that leads to the ultimate lower bound of an estimation error. We address here a ques…
Detecting non-decomposability of time evolution via extreme gain of correlations
Tanjung Krisnanda, Ray Ganardi, Su-Yong Lee +2
Non-commutativity is one of the most elementary non-classical features of quantum observables. Here we propose a method to detect non-commutativity of interaction Hamiltonians of t…
Two-particle indistinguishability and identification of boson-and-fermion species: a Fisher information approach
Su-Yong Lee, Jeongho Bang, Jaewan Kim
We present a study on two-particle indistinguishability and particle-species identification by introducing a Fisher-information (FI) approach---in which two particles pass through…
