What is remote quantum cryptography?

Remote quantum cryptography refers to the use of quantum mechanics principles to secure communications between parties located in different places, often over the internet or long distances. This approach leverages quantum key distribution (QKD), which ensures that encryption keys are exchanged in a way that is theoretically immune to eavesdropping. Remote quantum cryptography is considered highly secure because any attempt to intercept or measure the quantum keys disturbs them, alerting the communicating parties to potential security breaches. It is increasingly being explored for applications in finance, government, and other sectors requiring advanced data protection.
