Abstract: (288 Views)
In this article, an innovative protocol for ultra-dense quantum coding based on a four-qubit GHZ state has been developed. This novel protocol is designed to maximize the utilization of quantum systems' capacities and has been comprehensively examined from a theoretical perspective. In this regard, the coding capacity of the protocol has been compared with the Holevo bound, which determines the maximum information extractable from a quantum system. To validate the protocol, simulations were conducted using quantum computing software. For practical evaluation, the protocol was implemented on the IBM Quantum Computer, allowing researchers to compare theoretical and practical results. The experimental results indicated differences from the theoretical predictions; while the theoretical results assigned each state a 50% probability, in practical conditions, these values shifted to 50.19531% and 49.80469%. These discrepancies stem from environmental noise and qubit-environment interactions, which represent one of the fundamental challenges in quantum computing. This research not only addresses these challenges but also emphasizes the importance of finding solutions to reduce noise and improve measurement accuracy. Bar charts were used to display the results, providing an effective tool for visually presenting data and facilitating more precise analyses. The use of these charts simplifies the understanding of patterns and discrepancies within the data, enabling researchers to identify and analyze more details. Overall, this study, by offering a new protocol and meticulously examining the challenges and potentials of quantum technologies, makes a significant contribution to advancing knowledge in the field of quantum computing. These achievements can pave the way for further advancements in this emerging technology.
