SpecStage

class SpecStage(name)

Bases: Stage[InT, dict[tuple[tuple[str, Hashable], …], MetaCircuit]], ABC

First stage in every pipeline: converts an arbitrary spec into a keyed MetaCircuit batch.

Examples

• CircuitSpecStage: wraps one or more pre-built MetaCircuit instances into a batch (by position or by name).

• TrotterSpecStage: takes a Hamiltonian and decomposes it into one or more MetaCircuit entries via a trotterization factory.

Methods Summary

expand(batch, env)	Transform input (e.g. Hamiltonian) into a keyed batch of MetaCircuits.
reduce(results, env, token)	Identity by default; override if this stage reduces results.
