研究目的
To improve the storage capacity of quantum color image representation by proposing a new model (QRCI) that encodes color information using basis states of qubit sequences, and to facilitate quantum image processing operations with lower quantum cost.
研究成果
The QRCI model significantly improves storage capacity by 218 times compared to NCQI and reduces quantum cost for various image processing operations. It enables accurate retrieval of classical images and facilitates operations on channels and bit-planes. Future work should focus on quantum image encryption and developing more complex processing operations.
研究不足
The experiments are simulated on classical hardware due to the lack of quantum hardware, which may not fully capture quantum system behaviors. The model is specific to color images with size 2n×2n and may not generalize to other image types or sizes. Quantum cost comparisons are based on theoretical evaluations and may vary in practical implementations.
1：Experimental Design and Method Selection:
The study proposes the QRCI model, which uses quantum superposition and entangled qubit sequences to store color, bit-plane, and position information. Quantum circuits are designed for image preparation, retrieval, and processing operations. Theoretical models include quantum gates (e.g., NOT, Hadamard, controlled-NOT) and algorithms for operations like color complement and channel swapping.
2：Sample Selection and Data Sources:
A color digital image with size 2n×2n is used, with examples such as 'Lena' and 'Peppers' images of size 256×256. Data is simulated as no quantum hardware is available.
3：Data is simulated as no quantum hardware is available.

Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Steps include initializing quantum states, applying quantum gates (e.g., identity and Hadamard gates) to store information, and performing operations like U1 and U2 for preparation. Retrieval involves quantum measurement. Processing operations are implemented via designed quantum circuits.
5：Data Analysis Methods:
Quantum cost is evaluated using a method from Ref. [28], comparing costs of quantum gates (e.g., NOT gate cost δ, controlled-NOT gate cost 1). Simulation results are analyzed to verify effectiveness of operations.
