Here is a one-sentence summary of what a quantum computer is:
A quantum computer is a type of computer that uses quantum mechanics so that it can perform
certain kinds of computation more efficiently than a regular computer can.
There is a lot to unpack in this sentence, so let me walk you through what it is exactly using a simple example.
To explain what a quantum computer is, I’ll need to first explain a little bit about regular (non-quantum) computers.
What Is the Future of Tech: 23 Technologies by 2022
Security Cross-Cutting Issues
