Prepare-and-Send Verifiable Universal Blind Quantum Computation: Difference between revisions

MBQC required a set of the initial state for computation. The [[Glossary#Brickwork States|brickwork states]] used in [[Prepare-and-Send Universal Blind Quantum Computation]] are modified to [[Glossary#Cylinder Brickwork States|cylinder brickwork states]] which enables the client to embed a trap qubit surrounded by multiple dummy qubits without disrupting the computation. This state is universal and maintains the privacy of the client's preparation. The dummy qubits here do not take part in the actual computation as they are disentangled from the rest of the qubits of the graph state. Hence by adding them to the neighboring nodes of the trap qubits, they are blindly isolated and thus do not interfere with the actual computation. The dummy qubits are added next to the trap qubit in a tape format as seen in [[Glossary#Cylinder Brickwork States|cylinder brickwork states]].  

* '''Client's preparation''': The partially quantum client prepares the quantum states with embedded traps qubits and sends them to the server for creation of the cylinder brickwork state.
