The new open-source Python library blind_transpiler enables developers to convert Qiskit quantum circuits into secure, blind counterparts for applications in quantum homomorphic encryption and universal blind quantum computation.

Key Points

• Supports four distinct blind transpilation protocols: qhe, ubqc, fdqc, and ssdqc.
• Allows users to delegate complex quantum computations to remote servers without exposing input, output, or algorithmic data.
• Features a modular, four-layer architecture designed for robustness and compatibility with Qiskit primitives.
• Provides tools for estimating encryption key sizes and managing secure communication rounds between client and server.
• Available for installation via PyPI or direct source download under the Apache 2.0 license.

Why it Matters

This library simplifies the implementation of secure delegated quantum computing, a critical requirement for protecting sensitive data in cloud-based quantum environments. By automating the transpilation process, it lowers the barrier for researchers to prototype privacy-preserving quantum algorithms and cryptographic protocols.
