#P1001G. Oracle for f(x) = k-th element of x
Oracle for f(x) = k-th element of x
Description
Implement a quantum oracle on N qubits which implements a function f(x) = xk, i.e. the value of the function is the value of the k-th qubit.
For an explanation on how the quantum oracles work, see the tutorial blog post.
You have to implement an operation which takes the following inputs:
- an array of qubits x (input register),
- a qubit y (output qubit),
- 0-based index of the qubit from input register K (
).
The operation doesn't have an output; the "output" of your solution is the state in which it left the qubits.
Your code should have the following signature:
namespace Solution {
open Microsoft.Quantum.Primitive;
open Microsoft.Quantum.Canon;
operation Solve (x : Qubit[], y : Qubit, k : Int) : ()
{
body
{
// your code here
}
}
}
