U3 gate. For U2 gate- θ=π/2, and for U1 gate- θ=ϕ=0, respectively. This makes the U1-gate equivalent to the Rϕ-gate. Here we will be dealing with a general U3 gate and will calculate it’s parameters to solve a particular problem. Objective 1: Create the state given below using only one U3 gate: Eq.
