In recent years, there has been a substantial amount of research on quantum computers machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum computers areWe present a three-stage quantum cryptographic protocol based on public key cryptography in which each party uses its own secret key. Unlike the BB84 protocol, where the qubits are transmitted in only one direction and classical information exchanged thereafter, the

Quantum cryptography : Uncertainty in the service of privacy

In general, observing a quantum system disturbs it, and prevents the observer from learning its exact state before the observation. Therefore, if quantum systems are used to carry information, an eavesdropper, or even the intended recipient, be prevented from getting
