Adjustable bus-mediated coupling between remote qubits

摘要

An adjustable bus-mediated coupling system is provided. The adjustable bus-mediated coupling system includes a first input port connected to the first end of the variable inductance coupling element through a first resonator and a second end connected to the second end of the variable inductance coupling element through a second resonator Includes input ports. The first input port is configured to be coupled to the first qubit, and the second input port is configured to be coupled to the second qubit. The controller isolates the inductance of the variable inductance coupling element between the first qubit and the second qubit and a low inductance state to provide strong coupling between the first qubit and the second qubit. It is configured to control between high inductance states to provide isolation).
