Changelog

Sourced from QuantumToolbox's changelog.

[v0.44.0]

Release date: 2026-03-11

• Align with last changes in CUDA.jl v5.9.6+. Use GPUArrays.AbstractGPUSparseArray instead of CUDA.CUSPARSE.AbstractCuSparseArray to support more GPU backends. (#625)
• Update to DocumenterVitepress.jl v0.3. (#667)
• Add limit tests of the filter in liouvillian_dressed_nonsecular. In the limit of the filter width going to zero, we should recover the dressed liouvillian within secular approximation (see, e.g., https://doi.org/10.1103/PhysRevA.84.043832). (#669)
• Support generic AbstractMatrix for mat2vec. (#670)

[v0.43.1]

Release date: 2026-02-23

• Remove internal function _check_dims_to. (#657)
• Improve memory efficiency of liouvillian_dressed_nonsecular by implementing the filtering directly during the Kronecker product. (#656)

[v0.43.0]

Release date: 2026-02-04

• Restructure Dimensions and Space. Avoid using prod(::Dimensions) for getting matrix sizes, and instead use get_hilbert_size and get_liouville_size. (#600)
• Merge ProductDimensions and GeneralProductDimensions into ProductDimensions. The dimensions are now assumed to be always general. This simplifies the structure and usage of dimensions. (#649)
• Add support to time-dependent Hamiltonian and collapse operators in lr_mesolve. (#650)
• Adapt time evolution solver options as well as spre and spost identity type to input. (#653)

[v0.42.0]

Release date: 2026-01-17

• Allow specifying element types (eltype) for states and operators generating functions. (#641)

[v0.41.0]

Release date: 2026-01-12

• Introduce matrix_heatmap and matrix_histogram for visualizing operators. (#621)
• Allow rectangular eigenvector matrices in liouvillian_generalized and expand its documentation with proper citation. Rename it to liouvillian_dressed_nonsecular. (#624)
• Optimize liouvillian_dressed_nonsecular: avoid O(N⁴) dense filter matrices. (#627)
• Restrict CUDA.jl version compatibility to < 5.9.6 due to breaking changes in that release. (#630)
• Move from JuliaFormatter.jl to Runic.jl for code formatting. (#633)
• Improve eigsolve_al initial state handling and returned values and vectors. (#636)
• Convert tlist to promoted type in all time evolution solvers. (#638)

[v0.40.0]

Release date: 2025-12-21

• Add error message for bad input in state/operator generating functions (#603)
• Extend sesolve and mesolve to handle Operator and SuperOperator as initial conditions for propagator calculation. This introduces a states_type field to TimeEvolutionProblem. (#606, #619)
• Support time-dependent operators on dsf_mesolve (#610)
• Fix thermal_dm and enr_thermal_dm for extreme cases. (#614, #613)

[v0.39.1]

Release date: 2025-11-19

• Add spre and spost methods for ComposedOperator and cache propagator in every time evolution solver. (#596)
