openfermion.linalg.jw_number_restrict_state
Restrict a Jordan-Wigner encoded state to a given particle number
openfermion.linalg.jw_number_restrict_state(
state, n_electrons, n_qubits=None
)
Args |
state(ndarray or sparse): Numpy vector in
the space of n_qubits.
n_electrons(int): Number of particles to restrict the state to
n_qubits(int): Number of qubits defining the total state
|
Returns |
new_operator(ndarray or sparse): Numpy vector restricted to
states with the same particle number. May not be normalized.
