REVIEW OF QUANTUM SENSORS

Using quantum systems, properties or phenomena are particular ways to measure a physical quantity. Quantum sensors are eligible to reach sensitivities that are not justifiable due to the usual physics laws. This level of sensitivity is only accessible by the quantum mechanic world and its inspiring features such as the possibility for simultaneous atoms presence at the two different energy bands. Magnetometers based on superconductive quantum interference systems or atomic clocks are historic examples of quantum sensors. Recently, quantum sensing has become a separate branch of progressing investigations in quantum science and technology, which points to spin qubits, trapped ions, and flux qubits. According to the high sensitivity and accuracy of the quantum sensors, it can open many new opportunities in the realm of applicable physic and other scientific fields. In this study, we present an introduction to basic principles, concepts, and applications of quantum sensors.
