Implementing the Three-Stage Quantum Cryptography Protocol

TL;DR

This paper demonstrates practical implementations of Kak's three-stage quantum cryptography protocol, including scenarios where multiple qubits are transformed simultaneously, advancing the feasibility of secure quantum communication.

Contribution

It introduces simple implementation methods for the three-stage quantum cryptography protocol, including multi-qubit transformations, which are novel in this context.

Findings

Successful implementation of the protocol with single qubits.

Extension to multi-qubit transformations considered.

Potential for practical quantum secure communication demonstrated.

Abstract

We present simple implementations of Kak's three-stage quantum cryptography protocol. The case where the transformation is applied to more than one qubit at the same time is also considered.
