Two-qubit gate operations in superconducting circuits with strong coupling and weak anharmonicity
Two-qubit gate operations in superconducting circuits with strong coupling and weak anharmonicity
We theoretically study the implementation of two-qubit gates in a system of two coupled superconducting qubits. In particular, we analyze two-qubit gate operations under the condition that the coupling strength is comparable with or even larger than the anharmonicity of the qubits. By numerically solving the time-dependent Schrödinger equation under …
