Abstract (AI)
Quantum technologies are increasingly driving the field of precision metrology. While current techniques for sensing and recording time rely on classical devices, quantum sensors exploit quantum systems to reach unprecedented levels of precision. The working part of the sensor contains one or a few qubits, and resources like quantum entanglement are chosen and tailored to maximize sensitivity. This review introduces quantum sensing from the perspective of working experimentalists, with specific sensor implementations, concepts and methods, and recent developments.
Key Findings
1
Quantum entanglement can be selected and engineered as a resource to enhance quantum-sensing performance.
2
Quantum sensors use one or a few qubits as their active sensing element, with quantum resources tailored to maximize sensitivity.
3
Quantum technologies are advancing precision metrology by enabling sensing precision beyond that of current classical devices.
4
The review presents concrete sensor implementations, methods, concepts, and recent developments from an experimental perspective.
