AI Technical Summary
Existing methods for implementing a four-body interaction in superconducting quantum circuits, such as those described in NPL 1 and PTL 2, either lack a method to strengthen this interaction or require additional external inputs like microwave drive signals with specific phases.
A superconducting quantum circuit design featuring a coupler with a loop circuit and a parallel-connected capacitor, where the loop circuit comprises multiple Josephson junctions in series and a smaller Josephson junction in parallel, allowing the four-body interaction strength to be adjusted through circuit parameters.
The design enables a configurable and strengthened four-body interaction within the quantum circuit, enhancing its functionality without the need for external inputs.
