Title:
CAPACITIVELY-DRIVEN TUNABLE COUPLING
Document Type and Number:
WIPO Patent Application WO/2019/139799
Kind Code:
A1
Abstract:
A capacitively-driven tunable coupler includes a coupling capacitor (110) connecting an open end of a quantum object (104) (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 (108) having a Josephson element capable of providing variable inductance and therefore variable coupling to another quantum object (106).
