The computer history is made up almost 60-70 years ago. But how computer works it's just to organize the *switch* . Switch mean on and off that's like your light bulb in your house, ON is positive current and off it's no current . which mean it's symbolize as YES or No . or in the computer languange it's call Binary . 0 in binary represent OFF , then the 1 is ON and it's switch at difference milisecond or difference time . But... can you imagine that 0 and 1 can switch at the same time. Yes it can . So... in order to use conventional material as a silicon the D-WAVE use an single atom to represent 1 and 0 and even 1,0 . which mean that if you have one finger and one hand also one information , you're beable to carry one information . if you have 2 hand and 5 finger you're beable to carry that (one finger information) and the rest the others then you will send 4 and that 1 information with the same time . it same as you have more 1 virtual hand :D .
So in this case the Qubits or (1 and 0 at the same time) works with direction of an atom . If it's go up, it will be 1 . If it's go down it will be 0 . And If it's direction is circling it will be 1 and 0 .
so if you have 1024 in conventional computer number if you want 2048 you have to on another switch to be able to 2048 . But in the Quantum computer if you have 1024 which is 10 Qubits and you want to go to 2048 then you just add one Qubits which is 11 Qubits.
So conventional Computer Add more binary (+)
then Quantum Computer Multiply more binary (x) (if it's compare to conventional computer)
