Struct EfficientStateVector

pub struct EfficientStateVector { /* private fields */ }

A memory-efficient storage for large quantum state vectors

This provides memory-efficient storage and operations for quantum states, with support for chunk-based processing of large state vectors.

Implementations

impl EfficientStateVector

pub fn new(num_qubits: usize) -> QuantRS2Result<Self>

Create a new efficient state vector for the given number of qubits

pub fn num_qubits(&self) -> usize

Get the number of qubits

pub fn size(&self) -> usize

Get the size of the state vector

pub fn data(&self) -> &[Complex64]

Get a reference to the state data

pub fn data_mut(&mut self) -> &mut [Complex64]

Get a mutable reference to the state data

pub fn normalize(&mut self) -> QuantRS2Result<()>

Normalize the state vector

pub fn get_probability(&self, basis_state: usize) -> QuantRS2Result<f64>

Calculate the probability of measuring a specific basis state

pub fn process_chunks<F>( &mut self, chunk_size: usize, f: F, ) -> QuantRS2Result<()>

where F: FnMut(&mut [Complex64], usize),

Apply a function to chunks of the state vector

This is useful for operations that can be parallelized or when working with states too large to fit in cache.

impl EfficientStateVector

pub fn memory_stats(&self) -> StateMemoryStats

Get memory usage statistics
