Résumé : Quantum computing has attracted significant attention in areas such as cryptography, cybersecurity, and drug discovery. Due to the advantage of parallel processing, quantum computing can speed up the response to complex challenges and the processing of large-scale datasets. However, since quantum computing usually requires sensitive datasets, privacy breaches have become a vital concern. Differential privacy (DP) is a promising privacy-preserving method in classical computing and has been extended to the quantum domain in recent years. In this survey, we categorize the existing literature based on whether internal inherent noise or external artificial noise is used as a source to achieve DP in quantum computing. We explore how these approaches are applied at different stages of a quantum algorithm (i.e., state preparation, quantum circuit, and quantum measurement). We also discuss challenges and future directions for DP in quantum computing. By summarizing recent advancements, we hope to provide a comprehensive, up-to-date overview for researchers venturing into this field.
