Advanced Signal Processing and Deep Learning Architectures
This study employs a sophisticated methodology, starting with signal preprocessing through normalization and moving average smoothing. The core innovation lies in transforming time-series quantum emission signals into 128x128 RGB images using the Continuous Wavelet Transform (CWT) with Complex Morlet wavelet. This conversion allows the application of pre-trained convolutional neural networks (CNNs), which are highly effective for image classification. Three renowned CNN architectures—ResNet50, VGG16, and Xception—were implemented and evaluated using fivefold cross-validation across various band pair combinations to ensure robust assessment.
Exceptional Classification Accuracy and Efficiency
All deep learning models demonstrated exceptional classification performance. VGG16 achieved the highest overall mean accuracy of 99.4%, closely followed by Xception (99.1%) and ResNet50 (98.2%). Perfect classification accuracy (100%) was consistently achieved for spectrally distant band pairs, such as Band 1 versus Band 4 (20.5 nm separation). Even for the most challenging adjacent bands (Band 2 vs. Band 3, 6.27 nm separation), VGG16 maintained a remarkable 96.5% accuracy. Xception proved computationally efficient, achieving optimal convergence in as few as 2 epochs for certain band combinations while maintaining ultralow training loss values.
Transformative Potential for Quantum Technologies
The findings have significant implications for quantum photonics, quantum cryptography, and quantum sensing applications. The robust framework for quantum emission signal classification, especially when combined with CWT preprocessing, establishes quantifiable metrics for evaluating spectral distinguishability in quantum information systems. This approach bridges the gap between classical machine learning and quantum materials characterization. The demonstrated ability to achieve high classification accuracy with minimal training through transfer learning addresses data scarcity challenges inherent to quantum systems, paving the way for future quantum technology development.

Case Study: Quantum Materials Characterization in a Leading Photonics Lab
A leading quantum photonics laboratory faced challenges in rapidly and accurately classifying quantum emission signals from novel WS₂ monolayer nanobubbles. Traditional spectroscopic methods were proving too slow and prone to errors, particularly for spectrally similar emission bands. By adopting our CWT-based deep learning framework, the lab was able to automate the classification process. Using VGG16, they achieved an impressive 99.4% mean accuracy across various spectral bands, significantly accelerating their materials characterization workflow. This enabled them to identify and optimize quantum emitters with unprecedented speed, leading to a 20% reduction in experimental iteration time and a 15% increase in successful material synthesis cycles for their quantum device prototypes. The efficiency gained allowed their researchers to focus on developing next-generation quantum technologies, solidifying their competitive advantage.
