Quantum Technology in 6g

The need for ultra-reliable, fast, low-power, and secure communication has increased dramatically in recent years due to the rapidly evolving technological landscape. The promise of upcoming quantum computing (QC) to solve computer complexity in a reliable and effective way has piqued researchers' intense curiosity. It is anticipated that QC will play a pivotal role as potent enablers and catalysts to significantly lower computing complexity and improve the security of sixth generation (6G) and beyond communication systems in the future. The foundations of quantum communication (QC), which has evolved to incorporate a wide range of technologies and applications, and quantum key distribution (QD), one of the most promising uses of quantum security, have all been covered in this paper. In addition, several factors and significant methodologies are also examined to maximize 6G communication performance concerning security, computation, and communication effectiveness. Finally, future prospects and possible obstacles for quantum communication and quality control in 6G have been outlined.
