Description

Release of QuTiP 4.2.

Improvements
  • MAJOR FEATURE: Initial implementation of time-dependent Bloch-Redfield Solver.
  • Qobj tidyup is now an order of magnitude faster.
  • Time-dependent codegen now generates output NumPy arrays faster.
  • Improved calculation for analytic coefficients in coherent states (Sebastian Kramer).
  • Input array to correlation FFT method now checked for validity.
  • Function-based time-dependent mesolve and sesolve routines now faster.
  • Codegen now makes sure that division is done in C, as opposed to Python.
  • Can now set different controls for a each timeslot in quantum optimization.
  • This allows time-varying controls to be used in pulse optimisation.
Bug Fixes
  • rcsolve importing old Odeoptions Class rather than Options.
  • Non-int issue in spin Q and Wigner functions.
  • Qobj's should tidyup before determining isherm.
  • Fixed time-dependent RHS function loading on Win.
  • Fixed several issues with compiling with Cython 0.26.
  • Liouvillian superoperators were hard setting isherm=True by default.
  • Fixed an issue with the solver safety checks when inputing a list with Python functions as time-dependence.
  • Fixed non-int issue in Wigner_cmap.
  • MKL solver error handling not working properly.
