WiMi Explores the Application of Neural Networks in Parameter Optimization for Dual-Field Quantum Key Distribution

Published

BEIJING, June 29, 2026 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WiMi) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, announced that they are researching the use of neural networks for machine learning to optimize parameters in the dual-field quantum key distribution (TF-QKD) system. This innovative approach aims to leverage the powerful fitting ability and generalization performance of neural networks to directly predict the optimal parameter configuration for the TF-QKD system, significantly reducing computation time and resource consumption.

In the study, WiMi trained and evaluated three different types of neural network models:

Backpropagation Neural Network (BPNN): Based on the error backpropagation algorithm, BPNN minimizes prediction errors by continuously adjusting the network weights and biases. Due to its flexibility and wide applicability, BPNN has become the preferred model in many fields.

Radial Basis Function Neural Network (RBFNN): Using radial basis functions as activation functions for the hidden layer neurons, RBFNN efficiently handles nonlinear problems and is particularly suitable for high-dimensional data and scenarios requiring high precision.

Generalized Regression Neural Network (GRNN): Based on probability density estimation, GRNN uses kernel function methods to achieve nonlinear regression, excelling in handling small sample data and uncertainty issues.

Through training and testing these three neural network models, WiMi found that all models could accurately predict the optimal parameters of the TF-QKD system to some extent. Among them, RBFNN and GRNN performed especially well in high-dimensional parameter spaces, showing higher prediction accuracy. Compared to LSA, the neural network-based prediction method achieved a significant reduction in computation time, cutting it by multiple orders of magnitude. BPNN, due to its relatively simple structure, had the fastest computation speed; whereas RBFNN and GRNN, though slightly more complex in terms of computational cost, still remained within acceptable limits, and their enhanced prediction accuracy often brought more practical application value.

Considering the varying optimization needs of different TF-QKD systems (such as real-time requirements and precision demands), WiMi also conducted a comprehensive comparison of prediction accuracy and time consumption. The results indicate that for scenarios requiring rapid response with lower precision demands, BPNN is the ideal choice. On the other hand, for applications that prioritize high accuracy and can tolerate certain computation time, RBFNN or GRNN is more suitable.

The main technical advantage of using neural networks for TF-QKD system parameter optimization lies in significantly reducing the computational complexity of parameter optimization, accelerating the key generation rate, and enhancing the system’s real-time responsiveness. Neural networks can automatically learn and adapt to changes in the quantum communication environment, providing the possibility for dynamic adjustment of system parameters. As quantum communication technology develops, neural network models can be further upgraded and optimized to accommodate more complex quantum key distribution protocols and higher security requirements.

In the future, WiMi will continue to deepen its research into neural networks for TF-QKD parameter optimization, exploring more advanced neural network architectures and training strategies, such as deep learning, reinforcement learning, etc., with the aim of achieving more efficient and intelligent quantum key distribution systems. At the same time, it will strengthen integration with quantum communication hardware platforms to promote the practical application and commercialization of quantum communication technologies, contributing to the development of secure and efficient quantum communication networks.

Procurement Reviews Now Ask How AI Platform Data Is Deleted; FastGPT Publishes Retention Periods and Deletion Semantics

Retention windows for conversation records, model-call traces and audit logs are now documented with their configuration variables and defaults

HANGZHOU, China, Sept. 4, 2026 /PRNewswire/ — FastGPT, an open-source AI application platform for organizations, has consolidated in its public documentation how four classes of data are retained and removed: conversation records, knowledge base files, model-call traces and audit logs. The items were previously spread across a privacy policy, per-version upgrade notes and API reference pages.

For the cloud service, the privacy policy states that data deletion performed by a user is a physical deletion and is not recoverable, and that any non-physical deletion would be indicated in the service. The same policy states that user data is not kept as additional backup copies and is not used for model training. That page records its own last update as March 3, 2024.

Model-call traces used for short-term debugging are kept for six hours by default, adjustable through LLM_REQUEST_TRACKING_RETENTION_HOURS. Suspended agent sandboxes are archived after a period of inactivity set by AGENT_SANDBOX_ARCHIVE_INACTIVE_DAYS, with a default of seven days. Audit logs moved in the opposite direction in v4.16.0: on expiry they are transferred to cold archive storage rather than deleted, since traceability, not prompt removal, is what that class of data is kept for.

Three boundaries are documented alongside the defaults. The API endpoint that clears conversations affects only conversations created through an API key, and does not clear those from web use or shared links. Automatic cleanup depends on background tasks that can fail; two such defects were fixed in earlier releases, so a request to delete and a completed deletion should be verified separately. For community self-hosting and commercial private deployment, retention and cleanup are governed by the deploying organization, and the environment variables provide adjustable controls rather than a compliance conclusion.

About FastGPT

FastGPT is an open-source AI application platform offering RAG knowledge bases, visual workflows, agent orchestration, Skill, MCP and multi-channel publishing, available as a cloud service, community self-hosted, or commercial private deployment. As of Sept. 3, 2026, the GitHub repository labring/FastGPT has 29,551 stars and 7,297 forks across 275 releases, with v4.16.2 published on Sept. 3, 2026. Repository: github.com/labring/FastGPT

Bold Design, in Every Layer
TECNO POVA 8 Pro 5G Tonino Lamborghini Limited Edition builds around the most unmistakable elements of the Tonino Lamborghini design: the black-and-red palette of charisma and energy; and a hexagon pattern of strength and endurance.

At its center lies the Pulse Line — the arresting visual focal point inspired by mechanical precision and the flow of kinetic energy.  Encircling it is the Signature Shield hexagonal pattern. Thanks to a dual-layer stacking process, the rear panel offers a refined reflective quality and includes countless internal mirror structures that refract and redirect light. As the phone rotates, red elements surface from and then dive into the light and shadows, as if raw energy flushes across the surface of the phone.

Between the two layers, a physical height difference creates genuine spatial depth, recreating the layered geometry found in mechanical designs. The Tonino Lamborghini logo, rendered in a premium metallic finish, anchors the composition as the testament of the aesthetics.

The boldness extends through the entire user experience. A bespoke interface theme reworks dozens of icons in a black-and-red palette with glass-like material effects. The boot animation unfolds with the Pulse Line and crimson energy. A customized “L” signature, part of the brand heritage, effect appears on the Alive Matrix Display with other pre-defined scenarios and customization options. The ringtone is also bespoke.

The model, meanwhile, is also unmistakably POVA with the trinity camera module. A dedicated One-Tap Button on the side provides instant access to favorite apps, customizable gaming actions, and quick shortcuts. At 7.39mm thin, the model hosts a 6,500mAh battery.
