The Quantum Internet aims to create secure, high-speed communication networks using quantum mechanics. Unlike classical networks, which transmit data using bits, quantum networks use entangled qubits to enable instantaneous and unhackable data transfer.

Key components of a quantum internet include:

Quantum repeaters to extend entangled states over long distances.

Quantum teleportation for secure data transmission without physically sending information.

Quantum routers for distributing entangled particles efficiently.

China has already demonstrated the world’s first quantum satellite-to-ground communication using Micius, while research institutions worldwide are working on quantum network prototypes. By 2030, fully operational quantum networks could enable global-scale, unbreakable encryption for governments, financial institutions, and critical infrastructure.
