Reserchers from Keio University and Oxford University have successfully generated and detected quantum entanglement between electron spin and nuclear spin in phosphorus impurities added to silicon. This is the world's first successful generation and detection of entanglement, which is essential for quantum computing, in silicon, which is used as a semiconductor in all computers. This accomplishment constitutes a major breakthrough toward the achievement of quantum computers.
