The many other small improvements, bug fixes, documentation enhancements, and behind the scenese development changes are included in the list below. Import bugfixes include some bugs affecting plotting with matplotlib 3.5 and fixing support for qutrits (and other non-qubit) quantum circuits. Other significant improvements include better scaling of the Floquet solver, support for passing Path objects when saving and loading files, support for passing callable functions as e_ops to mesolve and sesolve, and faster state number enumeration and Husimi Q functions. This release sees the addition of two new solvers – qutip.krylovsolve based on the Krylov subspace approximation and that reimplements the BoFiN HEOM solver.īloch sphere rendering gained support for drawing arcs and lines on the sphere, and for setting the transparency of rendered points and vectors, Hinton plots gained support for specifying a coloring style, and matrix histograms gained better default colors and more flexible styling options. (#2038)Īdd a default max_step to processors. The suffix was accidentally removed in QuTiP 4.7.0. qu suffix to objects saved with qsave and loaded with qload. (#2012)įix parsing of package versions in setup.py to support packaging 22.0. (#2011)įix the hinton visualization method to take into account all the matrix coefficients to set the squares scale, instead of only the diagonal coefficients. (#1979)įix the hinton visualization method to plot the matrix instead of its transpose. (#1970)įix correlation for case where only the collapse operators are time dependent.

This fix updates QuTiP’s helper to match. Previously the print_figure function returned bytes, but since ipython/ipython#5452 (in 2014) it returns a Unicode string. (#1965)īackport fix for IPython helper Bloch._repr_svg_ from dev.major. (#1964)Ĭhange brmesolve to raise an exception when ode integration is not successful. (#1961)Ĭhange fidelity(A, B) to use the reduced fidelity formula for pure states which is more numerically efficient and accurate. Change floquet_master_equation_rates(…) to use an adaptive number of time steps scaled by the number of sidebands, kmax.
