Physics:Quantum weirdness

Short description: Unintuitive aspects of quantum mechanics

Quantum weirdness encompasses the aspects of quantum mechanics that challenge and defy human physical intuition based on the Newtonian mechanics of classical physics. These aspects include:

• quantum entanglement;
• quantum nonlocality, referred to by Einstein as "spooky action at a distance"; see also EPR paradox;
• quantum superposition, presented in dramatic form in the thought experiment known as Schrödinger's cat;
• the uncertainty principle;
• wave–particle duality;
• the probabilistic nature of wave function collapse, decried by Einstein, saying, "God does not play dice".

Many attempts have been made to construct an interpretation of quantum mechanics assigning a meaning to the laws of quantum mechanics in terms of an intuitively acceptable model. The so-called Copenhagen interpretation basically holds that the laws are as they are and need no interpretation in such a model.
