#P1002B4. Distinguish four 2-qubit states - 2
Distinguish four 2-qubit states - 2
No submission language available for this problem.
Description
You 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
}
}
}
