Struct QuantumRegister 

pub struct QuantumRegister { /* private fields */ }

An n-qubit quantum register holding 2^n complex amplitudes.

This is a higher-level wrapper around QuantumStatevector that tracks qubit count explicitly and provides convenience initializers.

Implementations

impl QuantumRegister

pub fn new(n_qubits: usize) -> Self

Create a new register in the |0…0⟩ state.

pub fn n_qubits(&self) -> usize

Number of qubits.

pub fn size(&self) -> usize

Number of basis states (2^n).

pub fn amplitude(&self, i: usize) -> Complex

Read amplitude at index i.

pub fn prob(&self, i: usize) -> f64

Probability of basis state i.

pub fn apply_gate(&mut self, gate: &Gate2x2, qubit: usize)

Apply a single-qubit gate to qubit q.

pub fn apply_cnot(&mut self, control: usize, target: usize)
