Special Issue Information

Dear Colleagues,

The use of quantum coprocessors for extensive and non-tractable computation routines in AI will lead to new machine learning and artificial intelligence applications.

However, we need a deeper understanding of the mathematical framework and the resulting constraints. What are the quantum machine learning applications? What are the advantages of quantum machine learning algorithms to combat various proposed artificial problems? Can we apply quantum machine learning and quantum AI for real-world applications?

Linear algebra-based quantum machine learning is based on quantum gates that describe quantum basic linear algebra subroutines. These subroutines exhibit theoretical exponential speedups compared to their classical counterparts and are essential for machine learning. The quantum algorithm for linear systems of equations is one of the main fundamental algorithms expected to provide an increase in speed compared to traditional algorithms. The algorithm is also called the HHL algorithm and is based on Kitaev’s phase algorithm. Quantum principal component analysis (qPCA) and quantum random-access memory (qRAM) have been previously described, and quantum kernels and quantum advantage kernels have already been introduced and identified. Still, there are many open problems, such as the efficient preparation of data or the estimation of the expected values that describe the results.

We discussed these problems in the Special Issue "Quantum Machine Learning 2022" and made much progress. Based on its success, we are continuing this trend with the current Special Issue "The Future of Quantum Machine Learning and Quantum AI".

Quantum machine learning holds the potential to revolutionize cancer treatment and diagnostic imaging by uncovering complex patterns beyond the reach of classical methods. This study explores the effectiveness of quantum convolutional layers in classifying ultrasound breast images for cancer detection. By encoding classical data into quantum states through angle embedding and employing a robustly entangled 9-qubit circuit design with an SU(4) gate, we developed a Quantum Convolutional Neural Network (QCNN) and compared it to a classical CNN of similar architecture. Our QCNN model, leveraging two quantum circuits as convolutional layers, achieved an impressive peak training accuracy of 76.66% and a validation accuracy of 87.17% at a learning rate of 1 × 10−2. In contrast, the classical CNN model attained a training accuracy of 77.52% and a validation accuracy of 83.33%. These compelling results highlight the potential of quantum circuits to serve as effective convolutional layers for feature extraction in image classification, especially with small datasets.
