About this Research Topic
During the new century, there have been notable advances in the area of quantum sensing, quantum communications and quantum computing. Therefore, the understanding, the modeling, the simulations and the engineering of the underlying physics at the basis of the operation of the novel generation of quantum sensors is of key importance. Thanks to the readjustment and rediscovery of well-known quantum phenomena and to the discovery of novel quantum effects belonging to fundamental physics, such as the quantum entanglement, quantum materials for sensing and communications and quantum computing, have become a breakthrough in the field of quantum innovation. A plethora of novel solid-state quantum sensors, such as magnetic, semiconductor, plasmonic and optical sensors, based either on well-known quantum effects or on novel quantum principles, have been manufactured and employed for several applications.
Recently, the field of quantum sensing has received a lot of attention from condensed matter physicists, material scientists and engineers. The goal of this Research Topic is to attract and invite world-leading scientists, working on any aspects of quantum sensors, to present the last exciting theoretical, numerical and experimental results in the field of quantum sensing, pointing out to the multiple facets of their underlying physics. For example, the novel generation of quantum magnetometers has been a recent advance and a real breakthrough in the sensor field. Quantum effects are also playing an outstanding role for semiconductors. For instance, in semiconductor oxides, these effects occur when the material dimensions are reduced to the nanoscale (few nanometers), giving rise to the modification of electronic and optical properties. The new quantum behaviors are the basis for the realization of a novel generation of chemical gas sensors having sensitivity, selectivity and operational functionalities never seen before. On the other hand, also the field of plasmonic and optical sensors has undergone notable advances during the last years both for the subtle and new underlying physics and for encouraging the manufacturing of novel materials to fabricate them.
One of the aims of fabricating novel quantum sensors of any types is undoubtedly the generation of ultrasensitive devices. Presently, quantum magnetometers have a leading role among the quantum sensors and are used for the detection of weak magnetization signatures via the combination of a high-dynamic range and a high bandwidth. For example, the exploitation of super-radiance quantum phenomenon in silicon carbide defects provide a route towards the fabrication of ultrasensitive quantum magnetometers such as super-radiance lasers of coupled atomic ensembles having a spectral resolution five order of magnitude larger than the quantum limit of conventional lasers. On the other hand, for example, the novel generation of chemical gas sensors exploiting the new quantum behaviors allows obtaining sensitivity, selectivity and operational functionalities never seen before.
