Quantum Image Representation on Clusters

We propose a novel scheme for quantum image representation using the cluster states (QIRC). This scheme is capable to represent images of any size and color. We emphasize the use of cluster states in this scheme due to its high entanglement and various experimental realization across several hardware. We also propose a secure image encryption scheme embedded with QIRC. Further, we discuss the possibility of QIRC to be implemented successfully with a real quantum device in the NISQ era, by executing example representations of a 2×2 and a 3×2 binary image on a real quantum processor provided by the IBM Quantum.
