If the first qubit is in the state 2/sqrt(5)|0> - 1/sqrt(5)|1> and the second qubit is in the state 1/sqrt(2)|0> - i/sqrt(2)|1>, what is the state of the composite system?
What is HX (1/5|0>+3sqrt2/(5)|+>)?
What is HX (1/5|0>+3sqrt2/(5)|+>)?
Quantum Physics
For HX (1/5|0>+3sqrt2/(5)|+>) the answer is:
7/(5*sqrt(2) |0> -1/(5*sqrt(2)) |1>
Does anyone have the answer for this one?
Let |ø⟩=1−i2|0⟩−1+i2|1⟩ and |ϕ⟩=2+i3|0⟩−2i3|1⟩. What is ⟨ø|ϕ⟩?
7/(5*sqrt(2) |0> -1/(5*sqrt(2)) |1>

For HX (1/5|0>+3sqrt2/(5)|+>) the answer is:
7/(5*sqrt(2) |0> -1/(5*sqrt(2)) |1>
answer is wrong??
7/(5*sqrt(2) |0> -1/(5*sqrt(2)) |1>
answer is wrong??

Did anyone get this:

Gyano
something must be wrong? kan you check again pls

What quantum state do you have to input in order to get output 1/sqrt2(|0>+ |11>)?
Don
a) If |u>= |v> = |+ >, what is the probability that the measurement outcome is 0 ?
b) If |u> = |+ > and |v> = |-> , what is the probability that the measurement outcome is 0 ?
b) If |u> = |+ > and |v> = |-> , what is the probability that the measurement outcome is 0 ?

The state of the composite system:
2/(sqrt(5)*sqrt(2)) in 00
2*i/(sqrt(5)*sqrt(2)) in 01
-1/(sqrt(5)*sqrt(2)) in 10
-i/(sqrt(5)*sqrt(2)) in 11
Can you help me with:
a) If |u>= |v> = |+ >, what is the probability that the measurement outcome is 0 ?
b) If |u> = |+ > and |v> = |-> , what is the probability that the measurement outcome is 0 ?
2/(sqrt(5)*sqrt(2)) in 00
2*i/(sqrt(5)*sqrt(2)) in 01
-1/(sqrt(5)*sqrt(2)) in 10
-i/(sqrt(5)*sqrt(2)) in 11
