Struct Qubit 

pub struct Qubit {
    pub alpha: Complex,
    pub beta: Complex,
}

A single qubit state α|0⟩ + β|1⟩ with |α|² + |β|² = 1.

Fields

alpha: Complex

beta: Complex

Implementations

impl Qubit

pub fn zero() -> Self

|0⟩ state.

pub fn one() -> Self

|1⟩ state.

pub fn plus() -> Self

|+⟩ = (|0⟩ + |1⟩) / √2.

pub fn minus() -> Self

|−⟩ = (|0⟩ − |1⟩) / √2.

pub fn prob_zero(&self) -> f64

Probability of measuring 0.

pub fn prob_one(&self) -> f64

Probability of measuring 1.

pub fn is_normalized(&self) -> bool

Check that |α|² + |β|² ≈ 1.

pub fn measure(&self, seed: u64) -> (u8, Qubit)

Perform a projective measurement.

Uses a simple deterministic hash of seed to decide the outcome. Returns (outcome, collapsed_state).

Trait Implementations

impl Clone for Qubit

fn clone(&self) -> Qubit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Qubit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
