摘要：
Two quantum Macro-states and their Macroscopic Quantum Superpositions (MQS) localized in two far apart, space-like separated sites can be non-locally correlated by any entangled couple of single-particles having interacted in the past. This novel "Macro-Macro" paradigm is investigated on the basis of a recent study on an entangled Micro-Macro system involving Na parts per thousand 10(5) particles. Crucial experimental issues as the violation of Bell's inequalities by the Macro-Macro system are considered.
