Quantum Logic Gates Solutions

Solutions for the exercises in Try Your Hand.

  1. The code for the quantum circuit is:

     qreg q[5];
     creg c[5];
     measure q[0] -> c[0];
     measure q[2] -> c[2];
    1. The concatenated string of measured states is 00000.

    2. Output on a simulator will look like this:


      The output on a simulator is exact: only the 00000 state is seen.

    3. Output on a real quantum computer will look something like the output shown.


      We see that the 00000 state is observed most often. But other states ...
