The Tianyan Quantum Cloud Platform, developed by the Tianyan Quantum Group, offers cutting-edge cloud services showcasing quantum advantage capabilities through the utilization of a Zuchongzhi 3.0-like superconducting quantum processor. This cloud-accessible superconducting quantum prototype, known as Tianyan-287, boasts an impressive 105 qubits and delivers exceptional operational fidelities. With single-qubit gates, two-qubit gates, and readout fidelity all exceeding 99%, this platform sets a new standard for quantum computing performance. One notable achievement of the Tianyan Quantum Cloud Platform is its efficiency in handling complex tasks. For instance, when tasked with random circuit sampling on a 74-qubit system across 24 cycles, the platform successfully completes one million samples in just 18.4 minutes. This remarkable speed and efficiency highlight the significant quantum advantage that this platform offers over conventional computing methods. To facilitate access and utilization of its advanced capabilities, the Tianyan Quantum Cloud Platform provides users with Cqlib, an open-source software development kit (SDK) specifically designed for working with quantum systems at an extended level of complexity. By offering tools to interact with quantum circuits, operators, and primitives, this SDK empowers researchers and developers to explore practical applications of quantum computing in various fields. Overall, the cloud service provided by the Tianyan Quantum Cloud Platform aims to democratize access to high-performance quantum hardware and enable the broader scientific community to validate and harness the transformative potential of practical quantum advantages. Through its state-of-the-art technology and user-friendly interface, this platform represents a significant step forward in advancing quantum computing research and applications on a global scale.
