Abstract:
A capacitively-driven tunable coupler includes a coupling capacitor connecting an open end of a quantum object (i.e., an end of the object that cannot have a DC path to a low-voltage rail, such as a ground node, without breaking the functionality of the object) to an RF SQUID having a Josephson element capable of providing variable inductance and therefore variable coupling to another quantum object.

Claim (Index 1):
A superconducting capacitively-driven tunable coupler system comprising:\n first and second quantum objects each having a ground end required to be connected to a DC path to a low-voltage rail and an open end required not to be connected to a DC path to the low-voltage rail; a coupler comprising:\n a first coupling capacitor connected between the open end of the first quantum object and a first connecting node; \n a radio-frequency superconducting quantum interference device (RF SQUID) connected between the first connecting node and a second connecting node, the RF SQUID comprising a Josephson element connected between the first connecting node and the second connecting node, wherein the entirety of a path between the first coupling capacitor and the Josephson element is electrically short; and \n at least one flux injection element configured to bias the Josephson element to variably weaken the strength of coupling between the first and second quantum objects, \n wherein the objects are coupled together to pass signals between them in the absence of injected flux.
