Changelog

This changelog track changes to the HQS noise app starting at version 0.5.0

0.16.6

• Updated to qonvert 0.14.0.

0.16.5

• Internal workflow fix.

0.16.4

• Updated dependencies.

0.16.3

• Added getters and setters to user documentation.

0.16.2

• Updated to qonvert 0.12.2. Fixes bug relating to routing converter skipping PragmaLoop.
• Fixes bug in SystemBathMSXXAlgorithm when creating a circuit. Set decomposition_blocks setting to true.
• Updated to roqoqo-quest 0.14.4-alpha.3
• Updated to alqorithms 0.13.2-alpha.0
• Switched from using construct_comparison_spin_system to create a circuit for the VariableMSXX system-bath algorithm to using SystemBathMSXXAlgorithm, introduced in alqorithms 0.13.2-alpha.0
• Bugfix for fit_boson_bath_to_spectral_function, where the resampling was failing for some fitting windows. Switched from using self._bath_fitter_resampling to spectral_function.resample, the in-built method for BRNoiseOperators.
• Updated to bath-mapper v0.12.2 (calculate_excitation_spectrum -> calculate_excitation_spectral_function renaming)
• Fixed bug in noisy_algorithm_model and system_bath_noisy_algorithm_model, where the trotter timestep was doubled for the creation of the circuits.
• Fixed bug in create_spin_circuit and create_sysmte_bath_circuit, where the symmetrisation was being applied unnecessarily. This led to the symmetrisation being applied twice in the cases where the normal circuit and symmetrisation circuits were built separately by hand.
• Updated to alqorithms 0.13.1
• Fixed issue ignoring background noise in bath-fitting by upgrading bath-mapper-rs/py to v0.12.2-alpha.1.

0.16.1

• Adds getters/setters to HqsNoiseApp python interface

0.16.0

• Updated to qonvert 0.11.0-alpha.1 which fixes the doubling of DecoherenceOnGateModel bug in "parallelization_blocks" mode.
• Added support for struqture 2.0 inputs, and moved internal logic from struqture 1.0 to 2.0
• Updated licensing package dependency that adds support for unknown entitlements

0.15.3

• Enabling option to use magine-id based license files

0.15.2

• Enabling working with licensefiel obtained by hqstage copy-license

0.15.1

• Update to add support for new entitlements

0.15.0

• Added unroll_quantum_program method that unrolls the symbolic loop inside the QuantumProgram created with the HQS Noise App into a sequence of Trotter timesteps after which each observable is measured. This can only be used with simulator backends and will omit stochastic effects of real measurements and errors in the single layer of basis rotation gates in real measurements.

• Added trotter_step and system_bath_trotter_step functions.
• Added qubit remapping information for bath connectivity.
• Added option to use symmetrization to trotter circuit
• Added option to add wait time to circuit

0.12.1

• Updated to component libraries to support empty coupling when constructing spectra
• Bugfix when fitting procedure tried system bath models with no coupling between system and bath

0.12.0

• Set scipy version to 1.11 due to an issue with qutip (doesn't work with 1.12)
• Fixes bug in construction of mappings for fermion-spin system bath quantum-program construction
• Added truncations for terms below numerical accuracy (1e-14) in fitting results for better stability
• Improved error messages so that users see which algorithms they should choose for which kind of system

0.11.0

• Update to component libraries includin bugfix in measurement preparation (adding wrong MeasureQubit operations)
• Enabled logical-to-physical qubit mappings for system and bath for ParityBased system bath algorithm
• Prepared to use bath-qubit-connectivity information to relax requirement for trilinear chains in when constructing system-bath.
