Struct Circuit 

pub struct Circuit<const W: usize> {
    pub num_qubits: usize,
    pub channels: Vec<Box<dyn Channel<W>>>,
}

A circuit on num_qubits qubits, stored as a heterogeneous list of channels.

Channels are held as Box<dyn Channel> rather than a generic enum so user-defined channel types can be appended at runtime; the engine sees only the trait. The engine reads the list in order for Direction::Forward propagation and in reverse (using each channel’s adjoint) for Direction::Heisenberg.

Examples

use paulistrings::{Circuit, channel::Clifford1Q};

let mut c = Circuit::<1>::new(2);
c.push(Clifford1Q::h(0));
c.push(Clifford1Q::s(1));
assert_eq!(c.len(), 2);

Fields

num_qubits: usize

Number of qubits this circuit acts on. Constrains the support of channels that can be pushed.

channels: Vec<Box<dyn Channel<W>>>

Channels in application order. Index 0 is applied first under Direction::Forward.

Implementations

impl<const W: usize> Circuit<W>

pub fn new(num_qubits: usize) -> Self

Empty circuit on num_qubits qubits.

pub fn push<C: Channel<W> + 'static>(&mut self, c: C)

Append a channel to the circuit.

pub fn len(&self) -> usize

Number of channels (gates + noise) currently in the circuit.

pub fn is_empty(&self) -> bool

true iff no channels have been pushed.
