Samples outside conserved symmetry sectors are rejected or reweighted as an error-mitigation step. This record separates the reusable method idea from any one molecule, Hamiltonian, optimizer, or device.
No input port at this edge: the record publishes no gate sequence and no register, so there is nothing here to read one off — and unlike a declared hole, nothing has been recorded about what belongs here.
Nothing in the Atlas meets this end.

This record is named by the layer graph at:
Takes A circuit, a target observable, a noisy device, a shot budget, and — for the model-based methods — a learned characterization of the device noise. Returns A bias-reduced expectation-value estimate, with a variance — equivalently a sampling overhead — that grows with circuit volume.
Samples outside conserved symmetry sectors are rejected or reweighted as an error-mitigation step. In a complete experiment, the method must be paired with a defined qubit Hamiltonian, reference state, parameterized circuit, measurement grouping, classical optimizer, stopping rule, and error analysis. The catalog therefore treats it as a literature-backed algorithm record rather than pretending that one generic snippet is the paper's implementation. Use the cited source to recover assumptions and compare energy error, variance, circuit resources, measurement cost, optimizer evaluations, and robustness under the same instance and budget.
METHOD: Symmetry-verified VQE
SCOPE: Samples outside conserved symmetry sectors are rejected or reweighted as an error-mitigation step.
This is a literature method record, not a fixed circuit.
Supply: Hamiltonian, reference state, ansatz, optimizer, measurement plan, and stopping rule.A reference record, not runnable source. Leona cannot execute it, so it cannot be saved to your Library as a circuit.
Compare Variational quantum eigensolver with the strongest classical method for the same instance, input budget, and output metric.
This reference exposes a quantum circuit pattern; it does not imply an application-level speedup without a matched benchmark.
Report input loading, circuit depth, repetitions, classical preprocessing, post-processing, and wall-clock time together.
Nobody has reviewed this record for gaps yet.
