Asymmetric Quantum Secure Multi-Party Computation With Weak Clients Against Dishonest Majority

This project is essentially a research paper (arXiv:2303.08865) and its accompanying reference framework. While the underlying math is highly sophisticated, the 'project' lacks a production-ready codebase, evidenced by its 0-star count and stagnant velocity. Its defensibility is low from a software perspective because the protocol is public and can be reimplemented by any entity with quantum expertise. However, its value lies in the 'Asymmetric' approach: most QSMPC protocols assume all parties have full quantum computers, whereas this allows 'weak clients' (capable only of state preparation) to participate. This aligns with the likely future of quantum computing—a centralized cloud model (e.g., IBM Quantum, Azure Quantum) serving limited end-users. The displacement horizon is long because hardware capable of running multi-party quantum gates with high fidelity does not yet exist at scale. It competes with other theoretical frameworks like Universal Blind Quantum Computing (UBQC) and verifiable delegated quantum computation. Frontier labs like OpenAI are currently uninterested in the quantum hardware/crypto layer, leaving this to specialized academic groups or quantum hardware giants like Google/IBM/IonQ who might eventually bake these protocols into their SDKs (Qiskit/Cirq).
