Quantum computers are getting increasingly large and available thanks to some major technological advancements, but they remain in the realm of NISQ (Noisy Intermediate Scale Quantum) devices. On such devices, due to the limited connectivity of the physical qubits, most quantum circuit-based programs cannot be executed without transpilation. this latter includes an important step, referred to as qubit mapping, which consists in converting the quantum circuit into another one which best matches the graph of physical qubits taking into account its limited connectivity constraint. In this paper, we propose a parallel Genetic Algorithm to Qubit Mapping (PGA-QM). the challenge is to minimize the depth of the transformed circuit and the execution time and error rate consequently. PGA-QM has been experimented using various medium-to-large scale circuit benchmarks. It is compared against the SABRE heuristic currently implemented in Qiskit, the IBM's library for quantum computing. the reported results show that PGA-QM can provide better solutions and with better consistency than its counterpart while parallelism greatly reduces its execution time during the transpilation.

Foggy weather conditions significantly impact the visibility required for autonomous vehicle navigation, resulting in performance degradation of on-road object detectors. Mobile computing devices deployed at the edge are often resource-constrained and cannot cope well withthe performance degradation of detectors. Image dehazing and ensuring the resource efficiency of dehazing algorithms are crucial for any navigation task of vehicle on the road. To ensure safe and smooth operation in foggy weather conditions, the clarity of the image needs to be improved. To address the challenges, an improved detection model called Lightweight Defog Detector (LDD) is proposed to improve detection performance. First, the dark channel prior and positional normalization algorithm is used to dehaze the image and improve image clarity. Second, a lightweight MOELAN feature extraction module is constructed, significantly improving detection efficiency and making it suitable for deployment on edge devices. Finally, the attention mechanism is introduced to further extract features from the feature maps used for detection, which improves the model's ability to extract feature information. Experiments are conducted on the foggy on-Road dataset. the experimental results show that compared withthe YOLOv9 and other models, such as IA-YOLO, the proposed algorithm has a slightly higher average accuracy and can effectively improve the performance of vehicle detection in foggy weather while reducing the parameters.
