Enum Exactness

Source

pub enum Exactness {
    Exact,
    Approximate {
        fidelity_lower_bound: Option<f64>,
    },
}

Expand description

Whether a result is exact for the circuit as given.

Variants§

§

Exact

§

Approximate

The engine that ran can discard state weight or estimate by sampling.

This marks the route, not the run: an MPS at bond 256 on a circuit that never fills a bond truncates nothing and still reports Approximate, with fidelity_lower_bound of 1.0. The variant answers whether the answer could have been approximated, the bound answers whether it was. None means the engine reports no bound.
