QUICHE

This research proposal addresses the emerging security and privacy challenges associated with the rapid development of quantum computers, advancements in qubit systems, and the proliferation of user-friendly quantum cloud applications. As access to quantum computing infrastructure becomes increasingly seamless, concerns regarding data protection, algorithm security, and the potential for information leakage through quantum hardware have become paramount. This project emphasizes the need for a comprehensive exploration of these issues, focusing particularly on quantum side-channel attacks. Special emphasis is paid on privacy implications of dynamic quantum circuits and the transition from qubits to qudits, which promise enhanced computational performance but may also introduce new vulnerabilities.

In general, our research aims to popularize applications for quantum computation by deepening our understanding of potential security risks, including a corresponding theoretical framework of information leakage based on entanglement and non-entanglement approaches as well as high-dimensional quantum systems. Building on preliminary cross-hardware security analyses, the project will expand the scope of investigation to include a wider array of side-channel attacks, supported by in-depth mathematical modeling to assess possible information leakage and develop secure qudit implementations. The proposal outlines plans to develop robust countermeasures to protect the privacy and integrity of quantum computing architectures, thereby enhancing the security of emerging quantum technologies.

Conducted by an interdisciplinary consortium of experts in quantum physics, computer science, cryptography, and mathematics, and supported by an international network of research partners, this project aims to make significant contributions to the design of secure quantum hardware and the safety of quantum cloud applications for end users.
