What are quantum computers? Why were they made? Will they soon become common objects?

These are important questions, with complex answers that we will try to reveal with simple words and concepts.

What can a quantum computer do?

If we have a sequence of 30 zeroes and ones, it has about one billion of possible values. However, a classical computer can only be in one of these one billion states at the same time. A quantum computer can be in a quantum combination of all of those states, called superposition.

Quantum field theory

"If you really understood quantum field theory in a proper mathematical way, this would give us answers to many open physics problems, perhaps even including the quantization of gravity.” Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields.
