A Remote Quantum Error-Correcting Code Preparation Protocol on Cluster States

The blind quantum computation (BQC) protocol allows for privacy-preserving remote quantum computations. In this paper, we introduce a remote quantum error correction code preparation protocol for BQC using a cluster state and analyze its blindness in the measurement-based quantum computation model. Our protocol requires fewer quantum resources than previous methods, as it only needs weak coherent pulses, eliminating the need for quantum memory and limited quantum computing. The results of our theoretical analysis and simulations show that our protocol requires fewer quantum resources compared to non-coding methods with the same qubit error rate.

In this paper, a remote quantum error correction code preparation protocol using a cluster state is introduced for blind quantum computation (BQC). The blindness of the protocol in the measurement-based quantum computation model is analyzed. Compared to previous methods, our protocol requires fewer quantum resources as it only requires weak coherent pulses, eliminating the need for quantum memory and limited quantum computing. Theoretical analysis and simulations demonstrate that our protocol requires fewer quantum resources compared to non-coding methods with the same qubit error rate.
