openfermion.linalg.jw_number_restrict_operator

Restrict a Jordan-Wigner encoded operator to a given particle number

Main aliases

openfermion.linalg.jw_number_restrict_operator(
    operator, n_electrons, n_qubits=None
)

Args
`sparse_operator`	`ndarray or sparse` Numpy operator acting on the space of n_qubits.
`n_electrons`	`int` Number of particles to restrict the operator to
`n_qubits`	`int` Number of qubits defining the total state

Args

Returns
`new_operator`	`ndarray or sparse` Numpy operator restricted to acting on states with the same particle number.

new_operator

ndarray or sparse

Numpy operator restricted to acting on states with the same particle number.
