Pseudo-Secret Random Qubit Generator (PSQRG): Difference between revisions

Secret Random Qubit Generator (SQRG) enables fully-classical parties to participate in many quantum protocols using only public classical channels and a single quantum server. This functionality can replace a secure quantum channel completely such that a classical Client can use it to perform various quantum applications such as delegated quantum computation. It could be used to carry out [[Secure Delegated Quantum Computation#Classical Online Communication-No Quantum Communication|Secure Delegated Quantum Computation]] by just classical online communication and no quantum communication. It allows a fully classical Client to hide her data such that she instructs Server to generate random qubits hiding her inputs and perform quantum computation on it via [[Prepare and Send-Universal Blind Quantum Computation|UBQC]] or [[Verifiable Universal Blind Quantum Computation|VUBQC]] . It hides the output, input and computation from the Server. It can find use cases in other protocols like Quantum Money, Quantum Digital Signatures etc.. which needs a user to share his/her private quantum key over a quantum channel.
