quantum key distribution protocols have been essential for the purpose of creating secure channels for long-distance transmission of quantum information. On the basis of ideas of quantum teleportation, this paper presents a novel quantum communication protocol utilizing the quantum entanglement and classical communication channels. Also, this paper aims to increase key generation rate and distance, achieve longer communication distances and higher key production compared to traditional QKD methods, improve resilience against eavesdropping and optimize system performance. quantum teleportation ensures the secure transfer of quantum states without exposing them to potential eavesdropping or interception, offering a higher level of security compared to traditional qubit- based protocols. This involves a thorough investigation of the Qiskit circuit implementations, operational procedures, and mathematical underpinnings of the protocol. Also, a thorough study of the protocol's performance with respected to some of the existing protocols like BB84, E91 and others using various metrics like QBER, key generation rate, adversarial resilience and. This project advances quantumkeydistribution systems and established the foundation for secure quantum communication networks.

quantum cryptography protocols leverage fundamental quantum computing principles such as superposition and entanglement, making them valuable tools for quantum computing education. While existing web platforms offer interactive interfaces to experiment with these protocols, none of them exploits the context in which cryptographic tasks are conducted: real-time communication between parties. We introduce quantumCrypto-an innovative framework designed to present quantum cryptography protocols as interactive experiences connecting multiple players. quantumCrypto aims to bridge the gap between theoretical quantum concepts and practical understanding by enabling users to engage in real-time simulations of quantum cryptography protocols. Our solution is extensible, allowing for the integration of new protocols. We demonstrate the versatility of our framework by showcasing the implementation of the BB84 protocol. Through detailed descriptions of the framework's backend and frontend components, we provide insights into its design and implementation. We also elucidate the learning experience of learners who used quantumCrypto to simulate the BB84 protocol, and provide suggestions for utilizing our tool in a learning environment. To conclude, we summarize our work and present ideas for integrating more quantum cryptography protocols in the future.

We develop an entanglement verification method not based on Bell inequalities, that achieves a higher reliability per number of qubits tested than existing procedures of this kind. Used in a quantum cryptographic context, the method gives rise to a new protocol for distributing classical keys through insecure quantum channels. The cost of quantum and classical communication is significantly reduced in the new protocol, while its security is increased with respect to other entanglement-based protocols exchanging the same number of qubits. To achieve this performance, our scheme relies on a simple quantum circuit and the ability to store qubits.

Even though there have been various proposed and wideley used ciphering techniques in cryptography, main improvements in this field came out with the idea of "super computing". Till now, popular methods like DES, AES and RSA which can be mathematically cracked in a duration of universe's age, have been proposed. But all of these methods's future is at risk because of the studies in production of "quantum Computer" s of which computation speed is estimated to be very high so that no other existing super computers compete with them. At this stage, by using quantum mechanics a new method called "quantumkeydistribution" and its protocols for the process of building cipher key, are proposed instead of determining new mathematical solutions for securing the data. In this study, a simulation project based on previously proposed quantum key distribution protocols BB84 and B92, will be explained. At the end of the project by using BB84 and B92 protocols, a comparison of quantum bit error rates and detection rates of eavesdropping according to protocols, is done and results are obtained.
