Struct GroverOracle 

pub struct GroverOracle {
    pub target: usize,
}

A Grover oracle that marks a single target basis state.

The oracle implements the phase-flip O|x⟩ = -|x⟩ if x == target, else |x⟩.

Fields

target: usize

The target basis state (integer index).

Implementations

impl GroverOracle

pub fn new(target: usize) -> Self

Create an oracle for the given target basis state.

pub fn apply(&self, reg: &mut QuantumRegister)

Apply the oracle phase-flip to the register amplitudes.

pub fn diffusion(reg: &mut QuantumRegister)

Apply the Grover diffusion operator (inversion about the mean) to the register.

pub fn run_grover(&self, n_qubits: usize, iterations: u32) -> QuantumRegister

Run Grover’s algorithm for iterations steps and return the register.
