Quantum communication is an advanced technology that uses the principles of quantum mechanics to transmit information securely. Unlike traditional methods, it leverages quantum properties such as superposition and entanglement to ensure that any attempt to intercept the communication is immediately detectable. This makes quantum communication highly resistant to eavesdropping and tampering, offering a new level of security for sensitive data transfer. Its most well-known application is quantum key distribution (QKD), which enables two parties to share encryption keys with guaranteed privacy, paving the way for safer digital communications in the future.
