Systems And Methods For Creating And Using Higher Degree Interactions Between Quantum Devices
A higher degree of interactions between qubits is realizable. This disclosure generally relates to devices, and architectures for quantum instruments comprising quantum devices and techniques for operating the same. Systems and processors for creating and using higher degree interactions between qubits may be found herein. Higher order interactions include interactions among three or more qubits. Methods for creating and using higher degree interactions among three or more qubits on a quantum processor may be found herein.

- 1. A quantum device comprising:
a first qubit; a second qubit; a third qubit; and a first coupler inductively coupled to each of the first, the second, and the third qubits by a respective mutual inductance, wherein the first coupler provides a third-order interaction or a higher-order interaction among the first, the second, and the third qubits.
- 24. A quantum device comprising:
three or more qubits; and a coupler inductively coupled to each of the three or more qubits by a respective mutual inductance, wherein the coupler at least one of optimizes or enhances at least one of a magnetic susceptibility having an order of at least two so as to provide a greater than pairwise interaction among the three or more qubits, or at least one of a pairwise or a greater than pairwise interaction among one or more subsets of the three or more qubits.
- 26. The quantum device of 24, wherein at least one of the three or more qubits is a superconducting qubit.
