Abstract
One or more systems, devices, or methods of use provided herein relate to a process of long-range coupling qubits in a quantum computing device with energy loss protection. A system can comprise a first transmon coupler capable of selectively coupling a first tunable coupler qubit to a first fluxonium qubit; a second transmon coupler capable of selectively coupling a second tunable coupler qubit to a second fluxonium qubit. Additionally, in one or more embodiments, the system can include a long-range coupler capable of selectively coupling the first fluxonium qubit to the second fluxonium qubit. The first transmon coupler can be coupled to a first B mode of the first tunable coupler qubit, and the second transmon coupler can be coupled to a second B mode of the second tunable coupler qubit.
