What is a Transistor in simple terms? A type of relay when power is applied to one leg of three legs, it allows power to flow the other two legs producing a 1 On or a 0 Off bit.
What is a Quantum Bit (Q-Bit)? A quantum bit uses the magnetic flux lines when the CPU is in sub zero cooling conditions in a shielded box that allows the Q-bit to accesses parallel dimensions to produce On, Off, On On, or Off Off all at the same time making for a CPU so powerful no conventional computer can match the power no matte how large the conventional CPU is.
The CIA has a D-Wave so does VW. VW is using it to monitor production of cars to fix manufacturing problems and other. I can only imagine what the CIA is doing with a machine that can exploit resources from another Dimension's.
The AI will be considered God's in our future. They will have power Wizards had and much more. Reality is much stranger than fiction.
