BosonicBasis

class BosonicBasis

GitHub

Bases: object

Basis to express a second quantization Bosonic Hamiltonian.

Methods

convert

BosonicBasis.convert(threshold=1e-06)

This prepares an array object representing a bosonic hamiltonian expressed in the harmonic basis. This object can directly be given to the BosonicOperator class to be mapped to a qubit hamiltonian.

Parameters

threshold (float) – the matrix elements of value below this threshold are discarded

Return type

List[List[Tuple[List[List[int]], float]]]

Returns

List of modes for input to creation of a bosonic hamiltonian in the harmonic basis

Raises

ValueError – If problem with order value from computed modes
