The brief

Analyst view

• Hosts Division of Quantum Physics & Information (Pan Jianwei, 2001) with leading superconducting and trapped-ion labs.
• March 2025: Zuchongzhi 3.0 unveiled, a 105-qubit processor with 99.9% single-qubit and 99.62% two-qubit fidelity.
• Zuchongzhi 3.0 surpassed Google's Sycamore by six orders of magnitude; deployed on Tianyan cloud with 37M+ global visits.

Technical approach

As reported

Materials

Niobium, aluminum, tantalum transmons

High-quality superconducting materials and topological coupling reduce noise and achieve high gate fidelities.

Coupling

Frequency-tunable qubits and topological coupling

Tunable qubit frequencies allow independent control of arbitrary pairs; improves layout and gate speed.

Integration

Flip-chip bonding for improved coherence

3D flip-chip integration of qubits with control circuitry reduces interconnects and electromagnetic losses.
