The goal of bootstrapping is to refresh a ciphertext and keep computing on encrypted data. Recall that{\texttt {HEAAN}}supports arithmetic operations on a characteristic zero plaintext space such as{\mathbb {C}}However, its decryption formula consists of two steps: the inner productt=\langle ...
The compression is repeated at each layer after the first, halving the number of hidden units each time, immediately after doubling it with UC gates. After the final layer, the RBM is parametrized by θopt, approximating the final QAOA target state \(\left|{\boldsymbol{\gamma }},{\bold...
