Quantum imaging is a relatively new and rapidly developing area of research that aims to exploit quantum mechanics to enhance imaging and sensing technologies. By utilizing quantum properties such as entanglement and superposition, quantum imaging techniques have the potential to achieve higher resolutions, sensitivities, and efficiencies than classical imaging methods. Quantum imaging encompasses a variety of different approaches, including quantum-limited imaging, quantum ghost imaging, and quantum illumination. These techniques have applications in fields such as medical imaging, remote sensing, and security imaging. Overall, quantum imaging has the potential to revolutionize the way we capture, process, and analyze images, leading to advancements in a wide range of practical applications.
