Superconducting quantum computing implements quantum computing with superconducting electronic circuits. Research in superconducting quantum computing is conducted by companies such as Google, IBM, IMEC, BBN Technologies, Rigetti, and Intel. As of May 2016, up to nine fully controllable qubits are demonstrated in a 1D array, and up to sixteen in a 2D architecture. In October 2019, the Martinis group, who partnered with Google, published an article demonstrating for the first time quantum supremacy, using a chip with 53 superconducting qubits.
