matchcake.observables package¶

Submodules¶

matchcake.observables.batch_hamiltonian module¶

class matchcake.observables.batch_hamiltonian.BatchHamiltonian(*args, **kwargs)¶

Bases: LinearCombination

__init__(*args, **kwargs)¶

eigvals()¶

Return the eigenvalues of the specified operator.

This method uses pre-stored eigenvalues for standard observables where possible and stores the corresponding eigenvectors from the eigendecomposition.

Returns:

array containing the eigenvalues of the operator

Return type:

array

eigvals_on_z_basis()¶

property name¶

String for the name of the operator.

reduce(expectation_values)¶

Use the expectation values and the coefficients of the Hamiltonian to compute the energy.

matchcake.observables.batch_projector module¶

class matchcake.observables.batch_projector.BatchProjector(states, wires, **kwargs)¶

Bases: Observable

__init__(states, wires, **kwargs)¶

get_batch_wires()¶

get_states()¶
