What are Quantum Communication Networks?
Quantum communication networks harness the power of quantum mechanics to create unbreakable encryption and unhackable channels for communication. By leveraging the principles of quantum entanglement and superposition, these networks enable secure data transfer between nodes, ensuring that any attempt to eavesdrop or intercept data would be detectable and thwarted.

How Do Quantum Networks Work?
Imagine two parties, Alice and Bob, separated by vast distances. They want to communicate securely, but the airwaves are filled with potential eavesdroppers. Quantum networks come into play here. When Alice wants to send a message to Bob, she generates a quantum key, which is a series of random, correlated quantum bits (qubits). This key is then transmitted to Bob through an optical fiber.
The catch? Any attempt to measure or intercept the qubits would inevitably cause them to decohere, or lose their quantum properties. This decoherence would be detectable by Bob, alerting him to potential eavesdropping. If the qubits arrive at Bob’s end without decohering, he knows the key is secure, and they can use it for encryption and decryption.
