Part 2 of the series highlighted threats from neo-attacks, especially quantum computers. But quantum technology is an answer to its own set of problems.
The process of encrypting data is called cryptography. It converts plain text into scrambled text so that someone with the right “key” can read it. Quantum cryptography, by extension, uses the principles of quantum mechanics to encrypt data and transmit it securely.
Quantum cryptography uses principles of quantum physics, such as:
- The subatomic particles in the universe follow probabilities of existence; they can be in more than one place.
- They can simultaneously hold the value of 0 and 1.
- Photons can randomly be in one of two quantum states.
- You cannot measure a quantum property without changing or disturbing it.
- You cannot clone a quantum particle.
Three-pronged approach
Quantum cryptography comes in three varieties:
Quantum Key Distribution
A unique key shared between the sender and receiver uses entangled quantum particles. An eavesdropper can be identified due to the inherent properties of entangled particles.
Quantum Random Number Generation
The unique properties of quantum physics allow the generation of truly random numbers. They do not follow any pattern; they are completely unpredictable. Quantum cryptography relies on this unpredictability.
Post-Quantum Cryptography
PQC refers to a set of quantum-safe cryptographic algorithms that can evade attacks from quantum computers.

A sense of urgency
Today, public-key encryption algorithms are used widely for encrypting data sent over the internet. The RSA-2048 public-key encryption provides the best combination of security and performance. It is believed to be extremely secure because it takes classical computers trillions of years to break the mathematics behind the encryption key exchange algorithms.
The superior computational power of quantum computers can break public-key encryption almost instantly. A quantum computer with 4099 perfectly stable qubits could break the RSA-2048 encryption in 10 seconds.
The importance of protecting critical and sensitive data using quantum-secured technology is the only path to secure our future. There is no time left to think and decide. The only plausible course of action is to plunge into adopting quantum security.
