Investigadores de la Universidad de Sevilla han demostrado mediante experimentos con microondas clásicas que ciertos resultados considerados característicos de partículas cuánticas son, en realidad, comunes a otros sistemas físicos. Según los autores, esto constituye un avance fundamental para identificar cuáles son verdaderamente los principios físicos de la teoría cuántica.

Our results have several implications: (I) The bounds of quantum correlations are not distinctive of QT. Hence, the principles determining the extent of quantum correlations (necessarily shared by universal models employing classical waves plus memory) are insufficient to grasp QT. This also means that even if quantum systems would not exist (and classical fields would be the fundamental physical objects), the so-called quantum bounds would still arise naturally. (II) The characteristic trait of QT rely on the fact that the quantum bounds are achieved without employing extra resources such as memory. Therefore, the principles needed to fully derive QT (in the spirit of Refs. [33–37]) should account for that. (III) Our model has at disposal more memory than strictly needed to simulate the quantum bounds: it has one bit of memory for each dichotomic decision, which is more than needed to simulate quantum probabilities (with this memory, one could simulate, e.g., a nonlocal box [5]).
