Quantum Key Derivation/Hashing Circuit (Gaussian Photonic Operations)

• this is a strawberryfields adaptation of the qash-qkdc hash circuit
• this notebook uses gaussian/photonic QPU operations to conduct hashes
• this circuit only works with gaussian backends (fock only simulators/devices not compatible)

Security Note: this circuit is not officially battle tested in any capacity and therefore unverified to be cryptographically secure, or programmatically useful in any manner

• If anyone wants to benchmark and/or pentest these circuits feel free to do so
• any feedback related to improving these circuits security and/or usability is highly appreciated
