What are Quantum Sensors?
At its core, a quantum sensor is a device that utilizes the principles of quantum mechanics to detect and measure physical phenomena. By leveraging the phenomenon of quantum entanglement, where two or more particles become linked in such a way that their properties are correlated, regardless of the distance between them, quantum sensors can achieve unprecedented levels of sensitivity and accuracy. This is particularly significant in applications where traditional sensors would struggle to detect faint signals, such as in the presence of background noise or interference.
