I,H X,H

what is the answer for these: (a) What is |ψ> in the standard basis? |0> = |1> =

III) 1/sqrt(2) 1/sqrt(2) -1/sqrt(2) 1/sqrt(2)

answer for this please: Let |ψ> = a|0>+b|1> where a and b are nonnegative real numbers. We know that if we apply H to this qubit and then measure the resulting state in the sign basis, the probability of getting a + is 1/4 (a) What is |ψ> in the standard...

Gyano -> is ok

2) LINE 1. 2/(sqrt(2)*sqrt(5) (2*i)/(sqrt(2)*sqrt(5)) LINE 2. -1/(sqrt(2)*sqrt(5)) -i/(sqrt(2)*sqrt(5)) What is the matrix (4x4) for ZX (Z applied on the first qubit and X applied on the second qubit)?

Let |ψ⟩=1−i2|0⟩−1+i2|1⟩ and |ϕ⟩=2+i3|0⟩−2i3|1⟩. What is ⟨ψ|ϕ⟩?

I calculated this for the Q1: (2+i+i^2)/6 But is not OK! some suggestion?

thks !! 9a... some help?¡

9b is 0.5 9a????? and 1???

IM in the same situation.. is not: 0.5 neither 0.25 Probably 1?

thank you!!! its correct...

Grazie!!
