Comprehensive cost metrics for a Hamiltonian in Pauli basis.

These metrics are encoding-dependent — comparing them across encodings reveals which encoding minimises a given cost for a particular molecule.

Record fields

Record Field	Description
`IdentityCoeff` Full Usage: `IdentityCoeff` Field type: `float`	Coefficient of the all-identity term (global energy offset). Field type: `float`
`LambdaNorm` Full Usage: `LambdaNorm` Field type: `float`	LCU 1-norm: Σ\|cₖ\|. Governs qubitization query complexity. Field type: `float`
`MaxPauliWeight` Full Usage: `MaxPauliWeight` Field type: `int`	Maximum Pauli weight (non-identity count) across all terms. Field type: `int`
`MeanPauliWeight` Full Usage: `MeanPauliWeight` Field type: `float`	Mean Pauli weight across all terms. Field type: `float`
`QubitCount` Full Usage: `QubitCount` Field type: `int`	Number of qubits the Hamiltonian acts on. Field type: `int`
`TermCount` Full Usage: `TermCount` Field type: `int`	Number of distinct Pauli terms (after like-term combination). Field type: `int`
`TotalPauliWeight` Full Usage: `TotalPauliWeight` Field type: `int`	Sum of Pauli weights across all terms. Proxy for total CNOT cost in Trotter. Field type: `int`
