The integration of quantum telecommunication enables state transfer between agents, reducing communication delays and facilitating instantaneous information exchange by encoding quantum information onto photons using properties like polarization or phase. The findings contribute to the growing body of knowledge in quantum communication and lay the foundation for practical applications of quantum computing in complex systems. By addressing challenges related to scalability, noise resilience, and wireless implementation, this research advances the understanding of quantum technologies and their potential to enhance coordination, security, and efficiency in real-world multi-agent networks.
Today’s mobile phones depend on towers, satellites, and the internet for communication. They need constant recharges, SIM cards, and network providers. But in the future, communication can become completely different with the help of Quantum Chips.
