Expand description

Trait for quantum noise channels

A noise channel is characterized by its Kraus operators {K_i}, which satisfy the completeness relation: ∑_i K_i† K_i = I

Required Methods§

Source

fn kraus_operators(&self) -> Vec<Array2<Complex64>> ⓘ

Returns the Kraus operators for this noise channel

Source

fn name(&self) -> &str

Returns the name of this noise channel

Source

fn num_qubits(&self) -> usize

Returns the number of qubits this channel acts on

Provided Methods§

Source

fn apply( &self, state: &ArrayView1<'_, Complex64>, ) -> NoiseResult<Array1<Complex64>>

Apply the noise channel to a quantum state using Kraus operators

For a state |ψ⟩, the noisy state is: ρ = ∑_i K_i |ψ⟩⟨ψ| K_i†

Source

fn verify_completeness(&self) -> bool

Check if Kraus operators satisfy completeness relation
