1] Let ψ⟩=(2+i/3)0>−(2/3)1>. If we measure ψ⟩ in the basis u⟩=(1+i/2)0>+(1−i/2)1>, u⊥>=1−i/20>−1+i/21>, what is the probability our outcome is u>?
2]Suppose we are trying to solve Simon's problem with n=4. We ran 4 iterations of Simon's algorithm and obtained 0000, 1101, 1010, and 0110. What is the secret string s? (Assume that s is not the allzero string 0000.)
3]What is the superposition that results if you apply the Hadamard transform H⊗n to the state 12√(0n>+1n>)? (Here, 0n⟩:=00⋯0n⟩ and 1n⟩:=11⋯1n⟩.)

any answers for Q1..

any hint or help for Q1

yup, but i need help in 4/9/12 any one would do

Anyone please can help with Q1.. have only one option left!

Any help for Q3, posted above here

Ans to q2 above, i can help with the other 2q's
