Quantum PKE & FHE Explained: Unlocking Quantum Algorithms & Cryptography 🔐

Welcome to 'Quantum Algorithms & Cryptography' course ! This lecture dives deeper into the QFHE scheme, explaining how to use TCF encryption and superposition over claws to perform an encrypted CNOT operation. It outlines a two-step process for achieving this: converting the FHE encryption to a TCF encryption and then using the TCF encryption to perform the encrypted CNOT. The lecture elaborates on the steps involved in both stages, highlighting the use of superposition over claws and the manipulation of the encrypted control bit.
