TwoQubitReduction

class TwoQubitReduction(num_particles)

ベースクラス: ConverterBase

Deprecated: Two qubit reduction converter which eliminates the central and last qubit in a list of Pauli that has diagonal operators (Z,I) at those positions.

Chemistry specific method: It can be used to taper two qubits in parity and binary-tree mapped fermionic Hamiltonians when the spin orbitals are ordered in two spin sectors, (block spin order) according to the number of particles in the system.

バージョン 0.24.0 で非推奨: The class qiskit.opflow.converters.two_qubit_reduction.TwoQubitReduction is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.

パラメータ

num_particles (Union[int, List[int], Tuple[int, int]]) – number of particles, if it is a list, the first number is alpha and the second number if beta.
