What Makes the Quantum Behavior of Macrosystems Possible?
In the journal Physics Today of July 2021, on p. 16, an article of Rachel Berkovitz was published “Macroscopic Systems Can Be Controllably Entangled and Limitlessly Measured” [1]. Based on these measurements, she claims: “quantum mechanic is not limited to the atomic scale. In principle, objects of all sizes should behave according to quantum mechanics”, but she does not explains why. In the present article, I am going to explain why objects of all sizes should behave according to quantum mechanics. In my article: “On the Universality of the Quantum Approach” [2], published in 2018, I claim: “At least now when we build quantum computers, we should acknowledge the fact that quantum mechanics is applicable to more than the microworld.”
