If you Fourier sample the state 122√(|000>−|001>+|010>−|011>+|100>−|101>+|110>−|111>), which of the following states can be the outcome of your measurement? Select all that apply.

1. |000>
2. |001>
3. |010>
4. |011>
5. |100>
6. |101>
7. |110>
8. |111>

    what is the answer??

  • Quantum physics -

    did you got any other answer?

  • Quantum physics -

    maybe it was a problem to read it:
    1/(2√2) * (|000>−|001>+|010>−|011>+|100>−|101>+|110>−|111>)

  • Quantum physics -

    how many answers ..its not all 8...

  • Quantum physics -

    how are you sure its not all 8???

  • Quantum physics -

    Help or any hint needed please.

  • Quantum physics -

    1 3 5 8 is the answer.....

  • Quantum physics -

    how many of you got 1 3 5 8 crt?

  • Quantum physics -

    @scholar its wrong

  • Quantum physics -

    then it must be 1 3 5 7.....
    otherwise am screwed

  • Quantum physics -

    Don't know...I have no options left sorry cant help... can you help with Q1 please

  • Quantum physics -

    you tried 1 3 5 8 for 12? do you 4 or 5?

  • Quantum physics -

    i got 1 correct.....

  • Quantum physics -

    yes: 1, 3,5, 8 was marked wrong.
    Q4:a)0 b) 1

  • Quantum physics -

    @scholar can you give some hint for Q1

  • Quantum physics -

    is it (sqrt5*sqrt2)/6 for q1

  • Quantum physics -

    q1 10/36

  • Quantum physics -

    any other 5 or 9 you got

  • Quantum physics -

    Thanks for your help scholar, I managed to pass.

    Q5: 1/sqrt3 and sqrt2i/sqrt3 ...put brackets after sqrt.

    Q9: CNOT12,CNOT23
    good luck

  • Quantum physics -

    How do you get number 6????

  • Quantum physics -

    did anyone get problem 11 correct???

  • Quantum physics -

    11 is d

  • Quantum physics -

    thanks scholar, can you help with number 6 also??

  • Quantum physics -

    Hey can any1 help me with question 10, on my last try, i cant seem to figure it out

  • Quantum physics -
