Quantum Computing Tunable Coupler with Non-Galvanic Coupling
Summary
USPTO published patent application US20260099740A1 for a tunable coupler with non-galvanic coupling interface for quantum computing applications. The invention by inventors Heinsoo and Ockeloen-Korppi includes a first constant coupling element forming a non-galvanic coupling interface to at least a first qubit. The application was filed on September 26, 2024 under application number 18898030.
What changed
USPTO published patent application US20260099740A1 for a tunable coupler designed for quantum computing systems. The invention describes a coupling mechanism with non-galvanic coupling interface that connects to qubits at a first extremity distant from the tunable coupling element. The tunable coupling element is positioned adjacent to a non-galvanic coupling interface formed as an interface to a circuit element.
Technology companies developing quantum computing hardware and quantum processors should monitor this patent filing. The tunable coupler technology addresses the challenge of maintaining qubit coherence while enabling adjustable coupling strengths, which is critical for scalable quantum processor architectures.

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.
