A Computing Perspective of Quantum Cryptography [Energy and Security]

In the continuous evolution of the computer age, the next big step in security is being achieved by embracing quantum cryptography. As the unit of information shifts from the currently used bit to the quantum bit (qubit), a new realm of untapped features is offered that can be used to ensure the confidentiality of the information being shared among participants. This system confidentiality is ensured by the use of a quantum channel for exchanging secret keys, which are then used to encrypt the data being shared. The system is a combination of cryptography and quantum computing that is aided by the laws of physics.
