B'Implement a quantum oracle on N qubits which implements the following function: f( vec{x}) = x_0 vee x_1 vee ... b vee x_{N-1} You have to implement an operation which takes the following inputs: and performs a transformation |x rangle|y rangle rightarrow |x rangle|y oplus f(x) rangle . The operation doesn 't have an output; its "output" is the state in which it leaves the qubits. Your code should have the following signature: '...
