Patent ID: 12015397

Abstract:
One or more systems, devices, and/or methods of manufacture and/or use provided herein relate to a quantum computing process to achieve higher connectivity of qubits to more than nearest neighbors and/or to a plurality of nearest neighbors. A system can comprise a tunable first coupler coupled to a first qubit, a tunable second coupler coupled to a second qubit, and a junction coupling the first coupler and the second coupler being both parametrically drivable. The first coupler and the second coupler can comprise superconducting quantum interference devices or Josephson junctions. The junction can comprise a central hub or central node separately coupled to the first coupler and the second coupler. The first coupler and the second coupler can be configured to capacitively or inductively couple the first qubit and the second qubit to one another to perform a control-Z (CZ) gate or an iSWAP gate.
