Enum ExpValueStrategy 

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

Strategy for computing expectation values in batch mode.

Variants

Native

Delegate directly to the backend’s native expectation-value primitive.

QubitWiseCommutation(usize)

Estimate expectation values using qubit-wise commutation grouping.

ClassicalShadows

Estimate expectation values using the classical shadows protocol.

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 shots per measurement round.
