Design of a novel quantum computing primitive to demonstrate quantum cryptography
摘要
Cryptography is the basis of modern life. With the advent of quantum computers public key based classical cryptography is no longer secure. So, Quantum Cryptography is the need of the hour. Quantum key distribution is the corner stone of quantum cryptography. Recent developments in quantum information and quantum computation have attracted attention from a large and diverse section of society. To cater the needs of such a large and diverse audience we have developed Quantum Ice-Cream, a pedagogical tool to describe the fundamental concepts of quantum cryptography in a simple and intuitive manner. Our work is inspired by the work of Karl Svozil. In this work we have improved upon the “Chocolate ball model” of Svozil and proposed a novel Quantum Ice-Cream model to demonstrate several different quantum key distribution protocols including the famous BB84 protocol and its variants. In addition to that we have also demonstrated quantum bit commitment and quantum icecream gates with our proposed quantum ice-cream model. The pedagogical tool we have developed can function as a valuable tool for educators of science and engineering to help lay people as well as scientists and researchers working in other areas to gain insight into the working of quantum cryptographic protocols.
