How Do Decoy States Work?

In a quantum network, decoy states are used to transmit quantum information, along with the original quantum state. The decoy states are designed to be easily distinguishable from the original state, allowing the receiver to detect any errors that may have occurred during transmission. This approach enables the receiver to correct errors and recover the original quantum state, ensuring the security and integrity of the communication.
