QuantumCTek — Guoshield (国盾量子)
◐ Design-level API
This page documents qalgora-Q API design, architecture, or adaptation workflows. Code examples illustrate intended usage and are not guaranteed to run in the current reference implementation.QuantumCTek (Hefei), China's pioneer in quantum communication, also reaches superconducting quantum computing through the Tianyan (天衍) quantum cloud platform (operated with China Telecom Quantum) and builds the control systems that drive large quantum processors.
Quantum computing at a glance
| Element | Detail |
|---|---|
| Cloud platform | Tianyan (天衍) superconducting cloud, public since November 2023, operated with China Telecom Quantum |
| Cloud processors | 176-qubit and 504-qubit (Tianyan-504, December 2024) superconducting platforms on the cloud, developed with USTC / CAS-affiliated teams |
| Zuchongzhi 3.0 | The USTC team's 105-qubit quantum-advantage system; some cloud prototypes relate to the Zuchongzhi line, but exact cloud device names and chip codenames follow Tianyan announcements |
| Control systems | Self-developed thousand-qubit-scale measurement & control — completed and delivered (2024) |
| SDK | Cqlib Python SDK |
The Tianyan cloud provides access to superconducting quantum processors developed with teams affiliated to USTC / the Chinese Academy of Sciences, including 176-qubit and 504-qubit platforms; some prototypes relate to the Zuchongzhi line, but the exact cloud device names, chip codenames, and accessible capabilities should follow the Tianyan cloud platform's announcements. The 天衍 cloud is not simply "the Zuchongzhi-3.0 original machine."
Vendor SDK workflow — submitting to the Tianyan cloud
Local validation runs; Tianyan submission is a planned adapter
The block below validates locally on the CPU simulator. The Tianyan submission lines are a
planned adapter workflow, commented out — they are not wired into the open
reference implementation.
import qalgora
# Local validation runs on the CPU statevector simulator:
qalgora.set_target("qpp-cpu")
counts = qalgora.sample(bell, shots_count=4000)
# Planned: submit the same gate-model kernel to the Tianyan cloud (async submit + poll).
# Requires the QALGORA_GUOSHIELD_TOKEN credential, gate-set transpilation, routing, and a device queue.
# qalgora.set_target("guoshield", machine="tianyan")
# job = qalgora.sample_async(bell, shots_count=4000)
# print(job.get())Reference build runs locally — not real hardware
This example targets a remote cloud/QPU, but the open reference build does not submit to a real machine — it warns and falls back to the local CPU statevector simulator, returning simulated results. Submitting to an actual device (e.g. 天衍/TianYan, IBM, IonQ, Origin) requires the vendor’s own SDK and credentials.More than computing
- Quantum communication — QuantumCTek built much of China's QKD backbone (including the Beijing–Shanghai trunk line) and satellite-ground links.
- Control electronics — its measurement-and-control systems are a key enabler for scaling superconducting processors past the thousand-qubit mark.
- Public listing — the first "quantum" stock on China's STAR Market (688027); China Telecom's quantum arm became its controlling shareholder in January 2025.
Gate-model — still needs adaptation
The Tianyan cloud runs gate-model kernels, but targeting it is not "change the name and nothing
else": you still need gate-set transpilation, coupling-map routing, shots configuration, SDK
credentials, and a device-queue check.

◐ 设计接口
本页描述的是 qalgora-Q 的接口设计、架构设计或适配工作流。相关代码用于说明预期用法，当前参考实现不保证可以直接运行。国盾量子（合肥）是中国量子通信领域的开拓者；在量子计算上，它通过天衍量子计算云平台（与中国电信量子集团联合运营）提供超导量子计算能力，并自研驱动大规模量子处理器所需的测控系统。
量子计算概览
| 要素 | 详情 |
|---|---|
| 云平台 | 天衍超导量子云，2023 年 11 月起向公众开放，与中国电信量子集团联合运营 |
| 云端处理器 | 云上接入 176 比特与 504 比特（天衍-504，2024 年 12 月）超导平台，与中国科大/中科院相关团队合作研发 |
| 祖冲之三号 | 中国科大团队的 105 比特量子优势系统；部分云端原型与祖冲之路线相关，但具体云端设备名称与芯片代号以天衍云公告为准 |
| 测控系统 | 自研千比特级量子测控系统，已研制完成并交付（2024） |
| SDK | Cqlib Python SDK |
天衍云接入了与中国科大/中科院相关团队合作研发的超导量子处理器，包括 176 比特、504 比特等平台；部分原型与祖冲之路线相关，但具体云端设备名称、芯片代号和可访问能力应以天衍云平台公告为准。天衍云并不等同于「祖冲之三号原机」。
厂商 SDK 工作流 — 提交到天衍云
本地验证可运行；提交到天衍为规划中的适配器
下方代码在本地 CPU 模拟器上验证；提交到天衍云的几行属于规划中的适配器工作流，已注释——它们尚未接入开放参考实现。import qalgora
# 本地验证在 CPU 态矢量模拟器上运行：
qalgora.set_target("qpp-cpu")
counts = qalgora.sample(bell, shots_count=4000)
# 规划中：把同一门模型内核提交到天衍云（异步提交 + 轮询）。
# 需要 QALGORA_GUOSHIELD_TOKEN 凭据、目标门集转译、布线，以及设备队列。
# qalgora.set_target("guoshield", machine="tianyan")
# job = qalgora.sample_async(bell, shots_count=4000)
# print(job.get())参考实现仅本地运行 · 非真机
此示例虽指向远程云端/QPU，但开放参考实现不会真正提交到真机 —— 它会给出告警并回退到本地 CPU 态矢量模拟器，返回模拟结果，不会真正提交到天衍等真机。真正提交真机需使用对应厂商的 SDK 与凭证。不止于计算
- 量子通信 —— 中国大部分 QKD 骨干网（含京沪干线）和星地链路都由国盾量子建设。
- 测控电子学 —— 其量子测控系统，是把超导处理器推上千比特规模的关键支撑。
- 上市公司 —— 科创板第一只「量子」股（688027）；2025 年 1 月，中国电信旗下量子公司成为其控股股东。
门模型 · 仍需适配
天衍云运行门模型内核，但对接它并非「换个名字、别处不用动」：仍需目标门集转译、耦合图布线、shots 配置、SDK 凭据和设备队列检查。
