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>

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 -

problem 8 anyone? im on my last try!!
