Quantum computers are just a whole theory that I don’t even understand too well

Combing quantum mechanics with computer science we can try and make something called a qubit which has the position of 1 and 0 at the same time (you gotta understand binary for that) And utilizing the qubit code we can make calculations with the quantum computer that could be millions of times faster than all of our supercomputers combined however for how they are made and the hardware I have 0 clue I only know about the qubits I just hope this helps
