What is quantum cryptography?
Quantum cryptography (also known as quantum encryption) refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.
While still in its early stages, quantum encryption has the potential to be far more secure than previous types of cryptographic algorithms and is even theoretically un-hackable.
Unlike traditional cryptography, which is built on mathematics, quantum cryptography is built on the laws of physics. Specifically, quantum cryptography relies on the unique principles of quantum mechanics
