Quantum Security is moving in two directions.
▪ Encryption using the characteristics of Quantum
▪ Encryption that remains secure in the age of Quantum computers
Encryption using the characteristics of quantum is called Quantum Security. Encryption that remains secure even in the age of quantum computers is called Post Quantum Cryptography (PQC).
Quantum is about very small size (10-12 cm) matter, covered in quantum physics, which exploits the properties of small particles such as molecules, electrons, protons, particles, protons, etc.
