The EPR paradox is commonly said to demonstrate an unobservable "spooky-action-at-a-distance" between entangled particles, suggesting that the universe is fundamentally non-local.

In this video, Oxford PhD researcher Maria Violaris resolves the EPR paradox without any instantaneous action-at-a-distance between entangled particles. Maria explains how to implement the thought experiment yourself on a quantum computer with Qiskit, tracking the local flow of information throughout the thought experiment and seeing how it is consistent with Bell's theorem and Bell-non-locality. Resolving the EPR paradox reveals how quantum systems can carry locally inaccessible information, that is robust to decoherence (without using Bell's hidden variables).
