Denoising diffusion models with optimized quantum implicit neural networks for image generation

Future Generation Computer systems 2025年 173卷

作者： Zhang, Jiale Che, Xilong Fan, Yuzhe Peng, Shun Chen, Geng Ma, Quangong Hu, Juncheng College of Computer Science and Technology Jilin University Changchun China School of Computer Science and Engineering University of Electronic Science and Technology of China Chengdu China School of Information Systems Engineering Information Engineering University Zhengzhou China

Denoising Diffusion Models (DDMs) have attracted significant attention due to their capacity to generate diverse, high-quality samples in computer vision tasks, offering flexible architectures and straightforward training processes. While several studies have extended diffusion models to quantum domains, these approaches often rely on hybrid U-net architectures or mixed-state manipulations with trace-out measurements, which pose substantial challenges for implementation on current quantum hardware. To address these challenges, we introduce an Optimized Quantum Implicit Denoising Diffusion Model (OQIDDM), which combines our proposed Optimized Quantum Implicit Neural Networks (OQINNs) with Consistency Models. OQINNs optimizes the complex network structures inherent in existing Quantum Implicit Neural Networks. By leveraging OQINNs to model image data distributions over multiple timesteps and employing Consistency Models for O(1) sampling steps, our approach is better suited for deployment on noisy quantum hardware. Experimental results on the MNIST, Fashion-MNIST, and E-MNIST datasets demonstrate that OQIDDM outperforms existing quantum diffusion models in terms of image quality, while requiring far fewer parameters in the quantum neural network. Compared to state-of-the-art quantum generative adversarial networks (QGANs) and classical GANs, our model notably enhances image generation quality while substantially reducing training parameters. Additionally, we present experiments on facial image generation, marking the first application of quantum denoising diffusion models to complex datasets. Analysis of quantum noise effects, along with experimental results on three different superconducting quantum computers, further underscores the considerable potential of OQIDDM for quantum generative tasks. © 2025 Elsevier B.V.

Multiparameter sensitivity analysis of tilt-to-length coupling noise in Taiji test mass interferometer

Tilt-to-length (TTL) coupling noise is a significant noise source for test mass interferometers in Laser Interferometer Space Antenna or Taiji, but identifying key parameters is a challenge due to the large number of influencing factors and complex interrelationships. Simulation models based on the heterodyne interference process and the signal readout of the test mass interferometer were constructed to generate a dataset containing different parameters and corresponding to the longitudinal path length noise caused by TTL coupling. The eXtreme Gradient Boosting (XGBoost) model was employed to fit the nonlinear relationships between the parameters and TTL coupling noise. Based on the fitting results of the XGBoost model, the sensitivity of single factor and multiple factors was performed using SHapley Additive exPlanation (SHAP) values and attribution value matrix, and the results were validated by the analytical models. Without reducing the fitting accuracy, the parameter dimension was decreased from ∼60 to 11 according to sensitivities, retaining those most relevant to angular misalignment. The results showed that the angle of the test mass, the angle of the beam splitters and mirrors, and the lateral offset of the test mass had a significant impact on TTL coupling noise. The introduction of machine learning methods into the study of TTL coupling contributes to a deeper understanding of noise mechanisms and provides references for optimizing the instrument design of the Taiji program. © 2025 SPIE.

As a new paradigm in the Web3 era, Decentralized Autonomous Organizations (DAOs) not only embodie the spirit of decentralization and collective governance, but also are the forefront of promoting community-led innovation. However, DAOs face challenges in sustainable growth and scalability in community governance, which are closely related to the income distribution model and member participation. Therefore, the Artificial systems, Computational experiments, Parallel execution (ACP) approach is applied to optimize the contribution evaluation and incentive feedback of member behavior through parallel governance and decision-making methods, so as to improve the intelligence of the DAO incentive mechanism. On this basis, the long short-term memory network (LSTM) and combinatorial game theory are used to conduct experimental verification on information sharing within the community. The experimental results show that our proposed method can not only achieve a high degree of information sharing in the community faster than other methods, but also has the ability of autonomous dynamic adjustment. It is of great significance and value to the community governance research and scenario implementation of DAOs. © 2024 IEEE.

Sharding is an effective technique to improve the scalability of blockchain. It splits nodes into multiple groups so that they can process transactions in parallel. To achieve higher parallelism and concurrency at large scales, it is desirable to maintain a large number of small shards. However, simply configuring small shards easily results in a higher fraction of malicious nodes inside shards, causing shard corruption and compromising system security. Existing sharding techniques hence demand large shards, at the expense of limited concurrency. To address this limitation, we propose CoChain: a blockchain sharding system that can securely configure small shards for enhanced concurrency. CoChain allows some shards to be corrupted. For security, each shard is monitored by multiple other shards. The latter reach a cross-shard Consensus on the Consensus results of their monitored shard. Once a corrupted shard is found, its subsequent consensus will be taken over by another shard, hence recovering the system. Via Consensus on Consensus, CoChain allows the existence of shards with more fraction of malicious nodes ( © 2023 IEEE.

Traditional urban transportation planning techniques cannot effectively deal with public transportation prob-lems due to many factors, such as the increase in the number of urban vehicles, the current state of inefficient traffic management system, unequal resource occupation in terms of time and space, and limited resources. There is congestion among the residents, and commuting times are unpredictable. Traffic congestion raises the risk of accidents, hinders economic expansion, and raises emissions. Nowadays, many see traffic congestion as a significant danger to city living. The pain brought on by a rise in car traffic, a lack of infrastructure, and ineffective traffic control has exceeded what is reasonable. This research suggests a computer vision-based traffic control system to solve the issues mentioned above. Data on traffic is optimized by the use of Improved Phase Timing Optimization (IPTO). This study focuses on average energy consumption, average network performance, average message delivery, average latency, and average access. Virtual environments were used for the entire trial. This demonstrates that our method can contribute to increasing the effectiveness of in-car Internet in the future.
