Governments all around the world, as well as public and private organizations, are continually looking for renewed data privacy improvements, such as the endpoint devices emerging today .
Quantum Base Ltd, which spun-off from Lancaster University in 2013, has created, and continues to create and patent a large range of unbreakable nanoscale quantum security devices, named Quantum IDs or Q-IDs. These solutions, built on scientific research in quantum physics and mechanics, provide advantages such as the small size and simplicity, with no need for large-scale computations, and prevent from attacks such as cloning, copying, and simulating. This cutting edge technology allows them to count on the financial support of The Royal Society, GCHQ, and the U.S. Air Force. 
This is related to the quantum cryptography, the science of exploiting quantum mechanical properties to perform cryptographic tasks. A key aspect of its security model is that it relies more on physics than mathematics. The quantum cryptography has the advantage that allows the completion of various cryptographic tasks that could not be done with classical communication.
