Interpretations of quantum theory: A map of madness

Understand

Motivated by some recent news, a journalist asks a group of physicists: "What's the meaning of the violation of Bell's inequality?" One physicist answers: "It means that non-locality is an established fact".

• Another says: "There is no non-locality; the message is that measurement outcomes are irreducibly random".
• A third one says: "It cannot be answered simply on purely physical grounds, the answer requires an act of metaphysical judgement".
• Puzzled by the answers, the journalist keeps asking questions about quantum theory: "What is teleported in quantum teleportation?" "How does a quantum computer really work?" Shockingly, for each of these questions, the journalist obtains a variety of answers which, in many cases, are mutually exclusive.
