Abstract
Quantum sensing presents an emerging technology in the field of metrology. It leverages principles of quantum mechanics (i.e. using the quantum states of subatomic particles such as electrons, photons and atoms) with advanced sensing techniques to achieve a significant step change in precision and sensitivity for a measuring system as compared to conventional sensor systems. Quantum sensing provides huge benefits for navigation, geophysics, medical imaging, amongst others. The concept of quantum sensing has progressed from its early theoretical conceptualisation to current experimental and practical applications. Progress in quantum physics and material science have been critical to this advancement, allowing for the development of more compact, efficient, and precise sensor devices. This chapter presents the development in methodology for quantum sensors, exploring fundamental concepts that underpin quantum sensing such as quantum superposition, quantum entanglement and quantum coherence with applications. Furthermore, areas for further research challenges are highlighted such as: the requirement for extreme operational conditions to preserve quantum states (e.g., low temperatures near absolute zero, vacuum, etc.), technical challenge with miniaturisation, dealing with noise and decoherence, development of novel materials with tailored properties, amongst others.
