- Abstract
The research of quantum image processing has gradually come into the attention of scholars in recent decade. However, the existing research results on quantum image processing almost are based on binary quantum system. In a novel enhanced quantum representation of digital images model (NEQR), for a quantum image with gray scale ranging from 0 to 255, eight qubits are needed to store the information of gray value. The follow question arises. How to use fewer quantum units to store a certain amount of information? Therefore, inspired by NEQR, this paper considers some research on quantum images in ternary quantum systems. In this case, for a quantum image with gray scale ranging from 0 to 255, six qutrits are needed to store the information of gray value. Therefore, a novel qutrit representation of quantum image (QTRQ) is proposed in this paper. In order to simplify quantum circuits, the paper designs a quantum image circuit compression scheme for QTRQ, which uses ternary logic function to compress quantum circuit. What's more, optimization rules of elimination, merger and movement are used to further simplify the circuit. An example given in this paper shows that the scheme has a fantastic result to simplify quantum circuits.
