"Quantum Entanglement Challenges Einstein's Theory and Advances Computing"

Researchers at ETH Zurich have performed a loophole-free Bell test with superconducting circuits, confirming quantum mechanics and disproving Einstein’s local causality concept. The findings open up possibilities in distributed quantum computing and quantum cryptography. The researchers were able to perform the experiment using superconducting circuits for the first time, which are considered promising candidates for building powerful quantum computers. The experiment confirms that superconducting circuits operate according to the laws of quantum mechanics too, even though they are much bigger than microscopic quantum objects such as photons or ions.
