"KANQAS: The Implications of Kolmogorov-Arnold Networks in Quantum Domain"
Abstract: The design of efficient quantum circuits is a pivotal challenge in quantum computing. KANQAS introduces a novel framework that enhances quantum architecture search (QAS) by integrating Kolmogorov-Arnold Networks (KANs) into deep Q-networks, replacing traditional Multi-Layer Perceptrons (MLPs). This talk will outline the KANQAS methodology and its application to tasks such as quantum state preparation and quantum chemistry problems. Notably, KANQAS demonstrates a 2–5 times higher probability of success than MLPs in noiseless scenarios, requiring fewer learnable parameters and exhibiting greater robustness against noise. We will explore the implications of KANQAS for achieving quantum advantage and discuss future research directions. By presenting this innovative approach, we aim to highlight its potential to significantly advance the field of quantum circuit design and its applications in real-world quantum computing.

"The Cost of Quantum Kernel Methods: Insights into Resource Estimation"
Abstract: Quantum kernel methods have emerged as promising tools in machine learning, particularly for tasks where computing kernel matrices efficiently can lead to significant advantages. These methods utilize quantum kernel estimation, which is theoretically believed to provide computational speedups, including exponential gains, in the construction of kernel matrices. Kernel matrices, essential in both supervised and unsupervised learning algorithms such as kernelized principal-component analysis and support vector machines (SVMs), reinforce many machine learning workflows.
In this talk, I will shortly review my work on the performance of quantum kernel SVMs application to remote sensing. Then, I will highlight the crucial role of resource estimation in evaluating the feasibility of quantum kernel methods, focusing particularly on the determination of the number of shots required in quantum circuits to achieve reliable kernel estimations. A key challenge here is the presence of barren plateaus and the phenomenon of exponential value concentration, which can severely impact the efficiency of quantum computations.
To address these challenges, I will introduce methods to estimate the number of shots necessary for accurate quantum kernel computation. I will present results from resource estimation analyses applied to a typical classification problem, demonstrating the practical implications for quantum machine learning. Finally, I will draw conclusions on the scalability and potential of quantum kernel methods, offering insights into their role in advancing machine learning applications.

Automated Quantum Machine Learning as Hyperparameter Optimization Problem
Abstract: A successful Machine Learning (ML) model implementation requires three main components: training dataset, suitable model architecture and training procedure. Same goes for Quantum ML (QML) models, although here the problem is slightly more specific. Often, when looking for an architecture, we're actually looking for a Parametrized Quantum Circuit (PQC) structure, or --- in the context of Quantum Neural Networks (QNN) --- we talk about Quantum Architecture Search (QAS) problem. In this talk, I'll present AQMLator, an AutoQML platform of our design, and present QAS as a Hyperparameter Optimization (HPO) problem. I'll also mention possible applications of such an approach.
