报告摘要：  

Superconducting qubits provide a promising platform for handling various types of computational tasks, including solidifying the fault-tolerant logical qubits for universal quantum computing, simulating nonequilibrium phenomena in quantum many-body systems, and solving combinatorial optimization problems for realistic applications. Here, I will introduce the different types of superconducting qubit devices that are being developed at Zhejiang University. In particular, I will describe our principles of developing these devices, with which we attend to achieve a balanced improvement of performance by taking into account key metrics such as qubit number, coherence, and gate/readout speed and fidelity. These devices are fabricated using the flip-chip recipe, with frequency-tunable transmon qubits/couplers on a substrate separated from that for control/readout wirings. The couplers are transmon type with long-range arms, capable of connecting distant qubits for direct two-qubit gates. I will present our experimental progress, with these devices, on quantum error correction, quantum simulation of topological phases, and performance benchmark of a hybrid quantum-classical search algorithm aimed at demonstrating quantum advantage.
