A major roadblock in using superconducting qubits to make large scale fault-tolerant quantum computers are their imperfect gate fidelities. The main source of these imperfections can be traced to the fundamental parasitic interactions between coupled qubits. The parasitic interactions bend the computational and non-computational levels of the qubits thus creating a parasitic ZZ interaction. In this poster, we provide a detailed overview of such parasitic interactions in a multi-qubit system and some techniques to suppress them. |
