- Abstract
- This thesis presents the Quantum Latent Generative Adversarial Network (QL GAN) framework to address the scalability issue of quantum GAN-based image gen eration methods. The QLGAN framework comprises two quantum machine learning models: a quantum autoencoder that compresses the quantum state into fewer qubits and a quantum GAN that learns the distribution of compressed quantum states. Ad ditionally, this thesis proposes the Quantum Image Autoencoder (QIAE), which is optimized for quantum probability image encoding. A bidirectional loss function is introduced to address the mismatch between loss and quality in image reconstruction. Experimental results shows that QIAE achieves state-of-the-art performance on image compression and reconstruction tasks over MNIST and FMNIST datasets. Further more, the combination of QLGAN and QIAE generates high-quality, high-resolution quantum images without the need for classical post-processing.
