Struct QuantumSimulationBackend 

pub struct QuantumSimulationBackend { /* private fields */ }

Backend for quantum circuit simulation.

This backend uses quantrs2_sim to execute quantum circuits and provides methods to convert results to PGM formats.

Implementations

impl QuantumSimulationBackend

pub fn new() -> Self

Create a new simulation backend.

pub fn with_config(config: SimulationConfig) -> Self

Create with custom configuration.

pub fn execute_state(&self, num_qubits: usize) -> Result<SimulatedState>

Execute a quantum simulation with given number of qubits.

For now, this creates an initial state. Full circuit execution will be integrated with quantrs2 in future versions.

pub fn sample_state( &self, state: &SimulatedState, num_samples: usize, ) -> Result<Vec<Vec<usize>>>

Sample from a state.

pub fn state_to_factor( &self, state: &SimulatedState, variable_names: &[String], ) -> Result<Factor>

Convert simulation results to a PGM factor.

Creates a factor representing the probability distribution over the measured qubits.

pub fn quantum_sample( &self, graph: &FactorGraph, num_shots: usize, ) -> Result<Vec<Assignment>>

Sample from a factor graph using quantum-enhanced methods.

This is a placeholder for QAOA-based sampling.

Trait Implementations

impl Default for QuantumSimulationBackend

fn default() -> Self

Returns the “default value” for a type.
