The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved when particles move very fast at velocities close to the speed of light, and even more so when those velocities are quantum mechanically indefinite.

Large objects behave in accordance with the classical laws of mechanics formulated by Sir Isaac Newton and small ones are governed by quantum mechanics, where an object can behave as both a wave and a particle. The boundary between the classical and quantum realms has always been of great interest. Research reported in AVS Quantum Science, considers the question of what makes something “more quantum” than another — is there a way to characterize “quantumness”?
