Enum ExpValueStrategy

pub enum ExpValueStrategy {
    DirectSample(usize),
    ClassicalShadows {
        bias: (u8, u8, u8),
        samples: usize,
        shots: usize,
    },
}

How the expected value of an Hamiltonian can be computed.

Variants

DirectSample(usize)

Using a sample for each observable.

ClassicalShadows

Using classical shadows.

Fields

bias: (u8, u8, u8)

Weights for selecting the random measurement basis (X, Y,Z).

samples: usize

Number of measurement rounds.

shots: usize

Number of shorts for each measurement round.
