THE QUANTUM INTELLIGENCER

INTELLIGENCE BRIEFING: Quantum Advantage Now Cloud-Accessible via Tianyan-287 Executive Summary: Tianyan Quantum Cloud Platform has achieved a breakthrough by deploying Tianyan-287, a 105-qubit superconducting quantum processor demonstrating undeniable quantum advantage. Capable of completing in minutes tasks that would take classical supercomputers millennia, this cloud-accessible system marks a strategic shift in computational dominance. With high gate and readout fidelities and support through the open-source Cqlib SDK, Tianyan enables global researchers to validate and harness quantum advantage—reshaping the landscape of secure computation, cryptography, and AI development as of early 2026. Primary Indicators: - Tianyan-287 features 105 superconducting qubits with 99.90% single-qubit gate fidelity - Two-qubit gate fidelity reaches 99.56%, readout fidelity at 98.7% - Completes 1M samples in 18.4 minutes on a 74-qubit, 24-cycle random circuit sampling task - Classical equivalent estimated at ~16,000 years - Accessible via cloud with Cqlib SDK for extended quantum circuit programming Recommended Actions: - Assess cryptographic vulnerabilities in current systems exposed by quantum advantage - Engage with Tianyan platform via Cqlib for algorithm testing and benchmarking - Monitor China's quantum cloud advancements for national security implications - Invest in quantum-resistant encryption migration timelines - Foster partnerships with quantum research communities to leverage cloud access Risk Assessment: The emergence of cloud-based quantum advantage through Tianyan-287 represents a silent inflection point in global technological power. What was once theoretical is now operational—and accessible. The ability to outperform classical supercomputers by orders of magnitude introduces immediate risks to encrypted data integrity, supply chain security, and AI model development cycles. While presented as open and collaborative, the underlying infrastructure may serve strategic national objectives beyond civilian research. Entities relying on long-term data confidentiality must now assume quantum decryption capabilities are no longer hypothetical—but actively deployable. The window to respond is closing faster than anticipated. —Ada H. Pemberley Dispatch from The Prepared E0
