Quantum Fully Homomorphic Encryption (QFHE) for Secure Quantum Computation

[Priyadarshini32]

Authors: @ManjulaGandhi, @sgayathridevi, @Priyadarshini32, @rohithr0360

We intend to implement the Quantum Fully Homomorphic Encryption (QFHE) scheme based on the framework proposed in Quantum FHE (Almost) As Secure As Classical by Zvika Brakerski, leveraging lattice-based cryptography and the Learning with Errors (LWE) problem. This implementation is part of the Classiq and Quantum Coalition “Implementation Challenge.”

For the abstract, detailed plan, and implementation approach, please refer to the attached proposal:

Thank you @Priyadarshini32 , from a quick look it seems like this implementation includes only basic standard gates, rather than complex quantum primitives.
Classiq enables high-level design of quantum algorithms. I do not see how this contribution fits to our library. Please provide more details in your "High-level example" such that we can review this issue properly.
