    Because some questions have a lot more than two possible answers (e.g. what is the enncryption key for this file?). A normal computer will have to try every possible sanswer one by one, whereas a quantum computer can try every possible answer at once.

    However, In order to answer a question like the above, the quantum computer would need to be able to process a lot more than the two bits that the Bristol computer can handle. This is the first step in that direction though.

    the processing power of the quantum computer grows exponentially whit the number of entangled qbits. so a 1 qbit qm can check 1 key at once, a 2 qbut can do 2 .
    but when you have a 10 qbit qm you can check 1024 keys at once. but you have to ask it multiple times to be sure that you got the right one.
