Google may have just ushered in an era of ‘quantum supremacy’

Google’s qubit circuits are built out of superconducting materials, which are then kept at very low temperatures. | Image: Google Google says that it has achieved quantum supremacy, a major milestone towards the development of quantum computers. At least, it seems to have. The announcement came in a paper that was reportedly published on the NASA website before being pulled, according to the The Financial Times which retrieved a copy before it disappeared. “To our knowledge,”
