B4. Distinguish four 2-qubit states - 2

standard inputoutput

standard outputYou are given 2 qubits which are guaranteed to be in one of the four orthogonal states:

Your task is to perform necessary operations and measurements to figure out which state it was and to return the index of that state (0 for , 1 for etc.). The state of the qubits after the operations does not matter.

You have to implement an operation which takes an array of 2 qubits as an input and returns an integer.

Your code should have the following signature:

namespace Solution {

open Microsoft.Quantum.Primitive;

open Microsoft.Quantum.Canon;

operation Solve (qs : Qubit[]) : Int

{

body

{

// your code here

}

}

}
