We design and realize parametric couplers connecting multiple superconducting qubits and investigate multi-qubit operations that allow us to entangle multiple qubits at the same time. We explore multi-qubit entangling interactions and evaluate the maximally possible number of qubits coupled to a single coupler. We aim to address the question if there is an advantage in using multi-qubit gates over traditional two-qubit gates in practical experiments. The devices and methods developed in this project will enhance the scalability of superconducting qubit platforms and the efficiency of quantum algorithms.
