Implementations§

Source§

impl StateVector

Source

pub fn new_zero_state(n_qubits: usize) -> QuantumResult<Self>

Construct |0⟩^n = [1, 0, 0, …].

Source

pub fn new_from_amps( amps: Vec<Complex<f32>>, n_qubits: usize, ) -> QuantumResult<Self>

Construct from a given amplitude vector; validates length = 2^n and unit norm.

Source

pub fn norm_sq(&self) -> f32

Sum of squared magnitudes: ‖ψ‖².

Source

pub fn normalize_inplace(&mut self)

Normalize in place; no-op if already unit.

Source

pub fn inner_product(&self, other: &Self) -> QuantumResult<Complex<f32>>

Inner product ⟨self|other⟩ = Σ conj(self[i]) * other[i].

Source

pub fn measure_prob(&self, qubit: usize, outcome: bool) -> QuantumResult<f32>

Probability of measuring qubit in state outcome.

Source

pub fn sample_measure( &self, qubit: usize, rng: &mut LcgRng, ) -> QuantumResult<(bool, Self)>

Sample a measurement of qubit, returning (outcome, post-measurement StateVector).
