Quantum for discovery,
quantum-safe for everything else.

Qianheng Quantum builds a quantum & quantum-inspired discovery platform — and AQtive Guard, our post-quantum migration suite. Every module is real, tested Python. An open mirror of SandboxAQ + Terra Quantum TQ42.

Two pillars

Quantum and quantum-inspired algorithms to accelerate discovery — and post-quantum cryptography to defend what matters.

Discovery

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. Explore all five domains →

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 AQAffinity CLI mirrors the real SandboxAQ/AQAffinity command exactly.

# install pip install aq-affinity # predict protein-ligand binding affinity (CLI matches real AQAffinity) 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.
