摘要 (Abstract)：
Superconducting circuits have emerged as a versatile platform, demonstrating significant potential for both large-scale quantum processors and advanced microwave quantum state manipulation. In this presentation, I will first introduce our recent progress in microwave quantum optics, including the rapid generation of Schrödinger cat states using a Kerr-tunable Superconducting Nonlinear Asymmetric Inductive eLement (SNAIL) resonator and the engineering of Bragg and anti-Bragg bandgaps in superconducting qubit arrays. These achievements underscore the capabilities of superconducting circuits for quantum optics applications. Next, I will present a scalable control technique for superconducting qubits based on single flux quantum (SFQ) circuitry. By integrating SFQ technology, we aim to overcome key bottlenecks in the development of large-scale quantum computing systems.
