Front Cover: Quantum Anomaly Detection with a Spin Processor in Diamond (Adv. Quantum Technol. 5/2024)

Abstract

Anomaly detection is crucial for identifying deviations from regular data. In article number 2300385, researchers from USTC (University of Science and Technology of China, Hefei) experimentally demonstrate the quantum anomaly detection with a spin processor embedded in a diamond, showing the quantum speedup in efficiently identifying anomalies. This cover illustrates that when a set of quantum samples, generated by a quantum machine (top-right), is transmitted to the diamond processor (bottom-right), the processor can learn its characteristics and identify whether a sample is an anomaly.
