quantum proof cryptography

Quantum proof cryptography is a way of making sure something stays secure even if an onlooker might have access to a super powerful computer known as a quantum computer.

A quantum computer is a very powerful computer that is able to process information much faster than a regular computer. It works by using quantum physics (the study of things like atoms and particles that make up matter) to process data much more quickly than a regular computer.

In order to keep data secure, it is important to keep it away from things like quantum computers, as they could easily break into the data and find out what it contains. This is where quantum proof cryptography comes in.

Quantum proof cryptography uses special algorithms that are designed to be strong and secure even if a quantum computer is used to try and break them. This means that data remains secure even if someone has access to a quantum computer.
