Scott’s Supreme Quantum Supremacy FAQ
Preface: I know nothing about quantum computing.What exactly is a qubit? I'm not asking what does it mean, because I know there's superpositions and all that jazz, but as in...like, in an electronic circuit, what is a qubit? Is it made out of logic gates? Which ones?If we can make one qubit, can't we just make a bunch of them by copy and pasting circuits similar to how we used vacuum tubes in the 60s and 70s? How come our current limit is only around 54 or so?Are qubits, and quantum computers by extension, not even electronic circuits? If so...what the hell are they?
