v0.2.0 · 36 modules · AGPL-2.0 compatible

Quantum for discovery,
quantum-safe for everything else.

Qianheng Quantum builds a quantum & quantum-inspired discovery platform — and Qianheng Guard, our post-quantum migration suite. Every module is real, tested Python. Built and open-sourced by Qianheng Quantum.

Three pillars

Quantum & quantum-inspired algorithms to accelerate discovery, post-quantum cryptography to defend what matters, and an orchestrator that lands each problem on the right backend with a trusted result.

Discovery

Discovery Platform

Quantum & quantum-inspired modules across biology, pharma, chemistry and AI. 36 tested packages, 20 interactive in-browser demos.

Post-quantum migration: discover RSA/ECC exposure, migrate to NIST ML-KEM / ML-DSA, and prove NIST + GM/T dual-compliance.

The execution layer beneath both. Submit a problem; it routes to the right backend, compiles, mitigates noise, and scores how much to trust the answer. The hard part was never the API — it's the decision.

4 domains

Quantum computing, domain by domain

From fusion to cryptography — where quantum computing actually stands, and where post-quantum (PQC) migration is the real commercial landing zone. Every domain is now deep-dived: directions, real players, timelines, and an honest advantage check. Explore all five domains →

NISQ

current hardware era

proven quantum-advantage cases

Nuclear fusion

Plasma MHD simulation, first-wall materials electronic structure (VQE), stellarator coil optimization — a mid/long-term research direction.

NISQresearch

Autonomous driving

Route planning and sensor-fusion optimization; the real landing zone is V2X comms needing post-quantum crypto to defend.

V2XPQC

Robotics

Motion planning and multi-robot coordination; industrial robot / AMR firmware & comms security compliance is the realistic story.

GM-evalPQC

Communications

Three threads: QC-optimized networks / quantum comms (QKD can't replace PQC) / QC as a threat to comms encryption (HNDL).

5G/6GPQC

Cryptography

Attack side: Shor / Grover break RSA/ECC; defense side: lattice-based ML-KEM / ML-DSA — the core thesis of the whole PQC business.

30-second quick start

The core QianhengAffinity CLI is the Qianheng Quantum Affinity command line.

# install pip install aq-affinity # predict protein-ligand binding affinity (CLI matches real QianhengAffinity) aqaffinity predict \ --protein MRIRKVLHTEMSPVTEEDFQAI \ --ligand 'CCOC(=O)c1ccccc1' \ --target_name BRD4 \ --output_dir /tmp/aq # or launch the browser dashboard python -m http.server --directory dashboard 8787 # → open http://localhost:8787/aq_platform.html

Real backends (opt-in)

Every integration lazy-loads. Installed? Real path. Not installed? Graceful stub fallback — no hard dependencies.
