TwoQubitReduction

class TwoQubitReduction(num_particles)

Bases: 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.

Obsoleto desde la versión 0.24.0: 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.
