Abstract
A tunable coupler for making a controllable coupling to at least a first qubit is disclosed. The tunable coupler includes a first constant coupling element and a tunable coupling element. The first constant coupling element forms a non-galvanic coupling interface to at least the first qubit at a first extremity that is distant from the tunable coupling element. The tunable coupling element is located adjacent to a non-galvanic coupling interface formed as an interface to a circuit element at a second extremity thereof.

A tunable coupler for making a controllable coupling to at least a first qubit, the tunable coupler comprising:
- a first constant coupling element;
- and
- a tunable coupling element,
- wherein the first constant coupling element forms a non-galvanic coupling interface to at least the first qubit at a first extremity of the first constant coupling element distant from the tunable coupling element, and
- wherein the tunable coupling element is located adjacent to a second non-galvanic coupling interface formed as an interface to a circuit element located at a second extremity of the first constant coupling element.
A quantum computing circuit, comprising:
- a tunable coupler comprising a first constant coupling element and a tunable coupling element;
- and
- at least one qubit,
- wherein the first constant coupling element forms a non-galvanic coupling interface to the at least one qubit at a first extremity of the first constant coupling element distant from the tunable coupling element, and
- wherein the tunable coupling element is located adjacent to a non-galvanic coupling interface formed as an interface to a circuit element at a second extremity of the first constant coupling element so that the tunable coupler forms a controllable coupling to the at least one qubit.
