Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

Quantum technology helps with the first three of these, but its performance is still quite slow. Still, the team was able to encrypt, transmit, and decrypt over 2GB of data using their quantum system.

Asymmetric encryption allows the recipient to verify and authenticate the origin of a message, making it easy to avoid encrypted messages from an unknown sender.

Post-quantum cryptography (PQC) refers to algorithms that are resistant to attacks by a quantum computer. Some of the methods include lattice-based cryptography, hash-based signatures and ...

By the 1900s, cryptography was mechanized in the form of encryption machines. The most famous was the German Enigma, used by the Nazis to encrypt their wartime communications.

Fortunately, post-quantum cryptography (PQC) solutions, essentially encryption services that can’t be decrypted by quantum computers, offer a strong answer to these next-generation threats.

With the global quantum cryptography market expected to grow from $89 million in 2020 to $214 million by 2025, IBM has been active in establishing itself as a leader within the space alongside ...
