Struct qip::pipeline::LocalQuantumState

pub struct LocalQuantumState<P: Precision> {
    pub n: u64,
    // some fields omitted
}

A basic representation of a quantum state, given by a vector of complex numbers stored locally on the machine (plus an arena of equal size to work in).

Fields

n: u64

Methods

impl<P: Precision> LocalQuantumState<P>

pub fn clone_state(&mut self, natural_order: bool) -> Vec<Complex<P>>

Clone the state in either the natural_order or the internal order.

pub fn set_multithreading(&mut self, multithread: bool)

Trait Implementations

impl<P: Precision> QuantumState<P> for LocalQuantumState<P>

fn new(n: u64) -> LocalQuantumState<P>

Build a new LocalQuantumState

fn new_from_initial_states(
    n: u64,
    states: &[QubitInitialState<P>]
) -> LocalQuantumState<P>

Build a local state using a set of initial states for subsets of the qubits. These initial states are made from the qubit handles.

fn n(&self) -> u64

Get number of qubits represented by this state.

fn apply_op_with_name(&mut self, _name: Option<&str>, op: &QubitOp)

Apply op with a given name. Mutate self using op.

fn measure(&mut self, indices: &[u64]) -> (u64, P)

Mutate self with measurement, return result as index and probability

fn stochastic_measure(&self, indices: &[u64]) -> Vec<P>

Measure stochastically, do not alter internal state. Returns a vector of size 2^indices.len()

fn get_state(self, natural_order: bool) -> Vec<Complex<P>>

Consume the QuantumState object and return the state as a vector of complex numbers. natural_order means that qubit with index 0 is the least significant index bit, otherwise it's the largest.

fn apply_op(&mut self, op: &QubitOp)

Function to mutate self into the state with op applied.

impl<P: Precision> Clone for LocalQuantumState<P>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
