What are the differences between quantum encryption and classical encryption?

What are the differences between quantum encryption and classical encryption?

Quantum encryption uses the principles of quantum mechanics to secure data, while classical encryption relies on mathematical algorithms.

Can you explain how quantum encryption works?

Sure! Quantum encryption, particularly Quantum Key Distribution (QKD), uses quantum bits (qubits) to create a secure key that can be shared between parties.

What are the advantages of using quantum encryption?

The main advantages include enhanced security against eavesdropping and the ability to detect any interception of the key.

Are there any limitations to quantum encryption?

Yes, quantum encryption requires specialized technology and infrastructure, which can be costly and complex to implement.

How does classical encryption compare in terms of security?

Classical encryption is secure but can be vulnerable to advances in computing power, such as quantum computers, which could break traditional algorithms.
