In theoretical physics, quantum nonlocality is the phenomenon by which measurements made at a microscopic level contradict a collection of notions known as local realism that are regarded as intuitively true in classical mechanics. Rigorously, quantum nonlocality refers to quantum mechanical predictions of many-system measurement correlations that cannot be simulated by any local hidden variable theory. Many entangled quantum states produce such correlations when measured, as demonstrated by Bell's theorem.
Experiments have generally favoured quantum mechanics as a description of nature, over local hidden variable theories. Any physical theory that supersedes or replaces quantum theory must make similar experimental predictions and must therefore also be nonlocal in this sense; quantum nonlocality is a property of the universe that is independent of our description of nature.
Whilst quantum nonlocality improves the efficiency of various computational tasks, it does not allow for faster-than-light communication, and hence is compatible with special relativity. However, it prompts many of the foundational discussions concerning quantum theory.
Within New Thought, we teach that as we change our thinking we change our lives..
- The concept of quantum nonlocality is about not judging by appearances.
- We learn that not only should be be cautious about judging a book by its cover, we should also be careful about doing the same with people.
- Science teaches us that there are many phenomena which cannot be properly interpreted with the human eye alone.
- We learn to use tools not only to craft our environment but also to understand it.
Together, we can attain deeper insights and support a more balanced world.
