Blind and Verifiable quantum remote state preparation protocol with classical channel

Quantum computers will be very expensive and require significant infrastructures, limiting their accessibility to the public. In this context it is essential to develop solutions that allow remote usage. We aim to enable blind remote usage, meaning that the servers are not aware of the computations they are performing.
While quantum networks make this possible, they are costly and hard to build. The combination of the so-called QFactory and Universal Blind Quantum Computation (UBQC) protocols allows to blindly delegate a quantum computation to a server without a quantum network. However, this approach does not guarantee that the server correctly performs the
requested computation. To address this issue, we combine the QFactory protocol with the protocol of Alexandru Gheorghiu and Thomas Vidick (GV19) that is similar to QFactory with weaker blindness security but verifies that the server has correctly prepared the qubits. The main objective is to have the best of both worlds: the blindness security with QFactory and the verifiability with GV19.
