A Sensitive Quantumness Measure for One-Dimensional Continuous-Variable Systems
Ole Steuernagel, Hsien-Yi Hsieh, Yi-Ru Chen +1
For one-dimensional continuous-variable quantum systems such as single-mode quantum optical systems, we give a quantification of the quantumness of such a system's state, ρ, by int…

Generation of heralded optical `Schroedinger cat' states by photon-addition
Yi-Ru Chen, Hsien-Yi Hsieh, Jingyu Ning +7
Optical "Schrödinger cat" states, the non-classical superposition of two quasi-classical coherent states, serve as a basis for gedanken experiments testing quantum physics on mesos…
