Photons in the quantum realm behave very differently from the classical light experienced in our everyday lives. The concept of nonclassicality—one of the most influential ideas of twentieth-century quantum physics—draws a boundary between these two regimes. Nonclassical light is also a valuable resource, underpinning exciting technologies that exploit the peculiarities of quantum physics, including ultrasensitive ...

Coherence and Discord are often thought as two distinct measures of non-classicality. The former a measure of non-classicality for single particles, the latter one for correlations. In this work, we designed an engineered experiment that illustrated how these resources can be inter-converted into each other. Experimental Cyclic Interconversion between Coherence and Quantum Correlations Kang-Da Wu, Zhibo ...
