Changelog

Sourced from QuantumToolbox's changelog.

[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)

[v0.39.0]

Release date: 2025-11-17

• Change default solver detection in eigensolve when using sigma keyword argument (shift-inverse algorithm). If the operator is a SparseMatrixCSC, the default solver is UMFPACKFactorization, otherwise it is automatically chosen by LinearSolve.jl, depending on the type of the operator. (#580)
• Add keyword argument assume_hermitian to liouvillian. This allows users to disable the assumption that the Hamiltonian is Hermitian. (#581)
• Improve accuracy of ODE solvers for general cases. (#586)
• Use LinearSolve's internal methods for preconditioners in SteadyStateLinearSolver. (#588)
• Use FillArrays.jl for handling superoperators. This makes the code cleaner and potentially more efficient. (#589)
• Make sure state generating functions return dense array by default. (#591)

[v0.38.1]

Release date: 2025-10-27

• Add ProgressMeterKWARGS in QuantumToolbox.settings for customizing progress bar. (#579)

[v0.38.0]

Release date: 2025-10-27

• Introduce new methods of sesolve_map and mesolve_map for advanced usage. Users can now customize their own iterator structure, prob_func and output_func. (#565)
• Use ProgressMeter.jl for progress bar rather than our in-house implementation. (#569, #575)
• Simplify type structure for time evolution solutions. (#572)
