B'Implement a quantum oracle on N qubits which implements a function f(x) xe2 x80 x89= xe2 x80 x89xk, 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: 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: '...
