(a) What is the inner product of the 3rd row and 14th row of this matrix?
b) What is the inner product of the 3rd row with itself?

C) Suppose we have a quantum circuit that takes the input |0> and outputs |+>, and also takes the input |1> and outputs −|−>. If we input √2*i/√3|+> + 1/√3|−>, what does the circuit output?

Any luck with the rest of the questions?

• Quantum physics -

yup, i got few questions, like 2 , 6 ,7 ,8

• Quantum physics -

• Quantum physics -

Got 7 and 8 for the moment!
can you help with the rest?

• Quantum physics -

ya.....but i need more question's answers to get 80%

• Quantum physics -

for c part i think the answer is 1/(sqrt3)for 0) and ((sqrt2)*i)/(sqrt3) for 1) ... i am not sure

• Quantum physics -

did anyone check with the above answer?

• Quantum physics -

nope......no chance left any luck for 9 or 12?

• Quantum physics -

help needed even for q.4 ...anyone?

• Quantum physics -

1 ques ans pls..

• Quantum physics -

can anyone tell me wats the ans of prob 2?

• Quantum physics -

any clue for 12, is it all 8?

• Quantum physics -

im missing 5 and 12 ..

• Quantum physics -

i tell you 5 and 12 you tell me 9

Help for Q. No 6

• Quantum physics -

i need 5 9 and 12 rest i will help

• Quantum physics -

6 then I will help with 5, 9 and 12

• Quantum physics -

Leave it.. Its not good to discuss exam questions outside. I don't know how i reached here.. i just realized i don't need course certificate, if I'm not worth it. So, I will try to solve it myself. You do too.. :)

• Quantum physics -

C) 1/sqrt(3)|0> + (sqrt(2)*i)/sqrt(3)|1>

• Quantum physics -

SS01: The answer to 12 is only 2.

I need 4 and 9.. can you give me the answers now?

• Quantum physics -

For question 9 the answer is
CNOT12, CNOT23

Thank you!

• Quantum physics -

4a 0
4b 1
12 2

how to find the state of the composite system in prob 2?? please ans

• Quantum physics -

ank, The answer to question 5 is

1/(sqrt(3))

in the first box and

(2*i)/sqrt(6)

in the second box.

• Quantum physics -

rare, for q2 - just multiply the two quibits states.

1/sqrt(2)*3/5 ----> |00>

(3*i)/(5*sqrt(2)) ----> |01>

4/(5*sqrt(2)) -----> |10>

(4*i)/(5*sqrt(2)) -----> |11>

• Quantum physics -

thanks..ans6- its 1 and 1/2

answer for Q3 is option 4

answer for Q11 is option 2

and let me know if any help needed

• Quantum physics -

thanks for help but Q3 and Q11 are false

• Quantum physics -

any help for Q 3 and 11

I am not sure what to tick.......

sorry anoy.....it was just a assumption.

• Quantum physics -

what is the answer of 3?

• Quantum physics -

Whats the solution of Question 1???

• Quantum physics -

1) 10/36 some help for Q3?

• Quantum physics -

any1 got the ans to q 10?

• Quantum physics -

Someone know answers for 7th and 10th? Attempts are finishing :(

• Quantum physics -

Someone give me Q3 and I give him/her all the others questions!

ANS TO 3 IS c
WATS Q10?

• Quantum physics -

@Anon, ans to question #10 is 1110

Can someone tell me the ans to question 5?

• Quantum physics -

@ Lord
The circuit is a phase change (Z) with a Hadamard (H); plug in the eqn (simple arithmetic if u understand the material)

TY for ans tho, wish i knew how u arrived to it, i wrote out all the y's and i couldn't figure out s

What is the superposition that results if you apply the Hadamard transform H⊗n to the state 12√(|0n⟩+|1n⟩)? (Here, |0n⟩:=|00⋯0n⟩ and |1n⟩:=|11⋯1n⟩.)

• Quantum physics -

answer of q 3. is 3rd option

• Quantum physics -

3/(5*sqrt(2)) |00>
(3*i)/(5*sqrt(2)) |01>
4/(5*sqrt(2)) |10>
(4*i)/(5*sqrt(2)) |11>

• Quantum physics -

answer 0f question 11 is option no. 4 and it is correct one, sure.
