Definition ∞ A quantum network is a communication system that transmits information using quantum mechanical principles. Unlike classical networks, it uses quantum states, such as photon polarization, to transmit data, enabling highly secure communication through quantum key distribution. This technology holds potential for creating intrinsically secure communication channels resistant to conventional eavesdropping. Its development is critical for future cryptographic security and distributed quantum computing.
Context ∞ The current discussion around quantum networks focuses on experimental implementations and the development of robust quantum communication protocols. A key debate involves overcoming technical challenges related to qubit stability, transmission distance, and network scalability. Future developments will likely involve the creation of distributed quantum computing architectures and ultra-secure communication infrastructure.
