The title says it all. If qubits can be in the position of a 1 and 0, why can’t multiple computers using 1s and 0s accomplish the same thing?

    Not just a one and a zero simultaneously, but every decimal in between. All infinity of them. This is the part that doesn’t scale well, classical computers don’t like infinity. Quantum computers love it.

      Actually, it’s explicitly not all in between. The quantum state is a super position, not a smear. It is (ideally) both 1 and 0, but nothing in between.

      It’s power comes when you have a multi bit number. 16 bits give 65536 possibilities. A classical computer would have to check each one individually to process them all. A quantum computer does them all in 1 go.

      While it gets very messy in the implementation, quantum computers are still binary, just quantum binary. No infinities needed
