qat.plugins.TransformObservable

class qat.plugins.TransformObservable(name: str)

Plugin performing a transformation on the Observable, to cast a qat.fermion.hamiltonians.FermionHamiltonian or a qat.fermion.hamiltonians.ElectronicStructureHamiltonian into a qat.fermion.hamiltonians.SpinHamiltonian. The transformation is defined by a identifier (i.e. string)

• jordan-wigner: Jordan-Wigner transformation (cf. transform_to_jw_basis())

• bravyi-kitaev: Bravyi-Kitaev transformation (cf. transform_to_bk_basis())

• parity-basis: Parity basis transformation (cf. transform_to_parity_basis())

Parameters

name (str) – Transformation

compile(batch, specs)

Compile method. Transform every job composing a batch

Parameters

• batch (Batch) – batch to compile

• specs (HardwareSpecs) – ignored argument

Returns

compiled batch

Return type
