This is a pre-release.

Continuation of the QuTiP 5 redesign.

It include fixing bugs and polishing features introduced in the alpha 1 release, updated stochastic solvers, a new solver: nm_mcsolve and animation functions.

Features

  • Add support for different spectra types for bloch_redfield_tensor (#1951)
  • Improve qutip import times by setting logger names explicitly. (#1981, by Pieter Eendebak)
  • Change the order of parameters in expand_operator (#1991)
  • Add svn and solve to dispatched (#2002)
  • Added nm_mcsolve to provide support for Monte-Carlo simulations of master equations with possibly negative rates. The method implemented here is described in arXiv:2209.08958 [quant-ph]. (#2070 by pmenczel)
  • Add support for combining bosinic and fermionic HEOM baths (#2089)
  • Added __repr__ to QobjEvo (#2111 by lklivingstone)
  • Improve print(qutip.settings) by make it shorter (#2113 by tamakoshi2001)
  • Create the trace_oper_ket operation (#2126)
  • Speed up the construction of the RHS of the HEOM solver by a factor of 4x by converting the final step to Cython. (#2128)
  • Rewrite the stochastic solver to use the v5 solver interface. (#2131)
  • Add Qobj.data_as to extract underlying data in original format. (#2141)
  • Add qeye_like and qzero_like (#2153)
  • Add capacity to dispatch on Data (#2157)
  • Added fermionic annihilation and creation operators. (#2166 by khnikhil)
  • Changed arguments and applied colorblind_safe to functions in visualization.py (#2170 by Yuji Tamakoshi)
  • Changed arguments and applied colorblind_safe to plot_wigner_sphere and matrix_histogram in visualization.py (#2193 by Yuji Tamakoshi)
  • Added Dia data layer which represents operators as multi-diagonal matrices. (#2196)
  • Added support for animated plots. (#2203 by Yuji Tamakoshi)
  • Improved sampling algorithm for mcsolve (#2218 by Daniel Weiss)
  • Added support for early termination of map functions. (#2222)

Bug Fixes

  • Add missing state transformation to floquet_markov_mesolve (#1952 by christian512)
  • Added default _isherm value (True) for momentum and position operators. (#2032 by Asier Galicia)
  • Changed qutip-notebooks to qutip-tutorials and fixed the typo in the link redirecting to the changelog section in the PR template. (#2107 by Valan Baptist Mathuranayagam)
  • Increase missing colorbar padding for matrix_histogram_complex() from 0 to 0.05. (#2181 by SJUW)
  • Raise error on insufficient memory. (#2224)
  • Fixed fallback to fsesolve call in fmmesolve (#2225)

Removals

  • Remove qutip.control and replace with qutip_qtrl. (#2116)
  • Deleted _solve in countstat.py and used _data.solve. (#2120 by Yuji Tamakoshi)
  • Deprecate three_level_atom (#2221)
  • Deprecate orbital (#2223)

Documentation

  • Add a guide on Superoperators, Pauli Basis and Channel Contraction. (#1984 by christian512)
  • Added information on sec_cutoff to the documentation (#2136 by Gerardo Jose Suarez)
  • Added inherited members to API doc of MESolver, SMESolver, SSESolver, NonMarkovianMCSolver (#2167 by Cristian Emiliano Godinez Ramirez)
  • Corrected grammar in Bloch-Redfield master equation documentation (#2174 by Andrey Rakhubovsky)

Miscellaneous

  • Update scipy version requirement to 1.5+ (#1982 by Pieter Eendebak)
  • Added all to qutip/measurements.py and qutip/core/semidefinite.py (#2103 by Rushiraj Gadhvi)
  • Restore towncrier check (#2105)
  • qutip.ipynbtools.version_table() can now be called without Cython installed (#2110 by Rushiraj Gadhvi)
  • Moved HTMLProgressBar from qutip/ipynbtools.py to qutip/ui/progressbar.py (#2112 by Harsh Khilawala)
  • Added new argument bc_type to take boundary conditions when creating QobjEvo (#2114 by Avatar Srinidhi P V )
  • Remove Windows build warning suppression. (#2119)
  • Optimize dispatcher by dispatching on positional only args. (#2135)
  • Clean semidefinite (#2138)
  • Migrate transfertensor.py to solver (#2142)
  • Add a test for progress_bar (#2150)
  • Enable cython 3 (#2151)
  • Added tests for visualization.py (#2192 by Yuji Tamakoshi)
  • Sorted arguments of sphereplot so that the order is similar to those of plot_spin_distribution (#2219 by Yuji Tamakoshi)
