Version 4.5.0 (January 31, 2020)
++++++++++++++++++++++++++++++

Improvements

  • MAJOR FEATURE: Added qip.noise, a module with pulse level description of quantum circuits allowing to model various types of noise and devices (by Boxi Li).

  • MAJOR FEATURE: Added qip.lattice, a module for the study of lattice dynamics in 1D (by Saumya Biswas).

  • Migrated testing from Nose to PyTest (by Tarun Raheja).

  • Optimized testing for PyTest and removed duplicated test runners (by Jake Lishman).

  • Deprecated importing qip functions to the qutip namespace (by Boxi Li).

  • Added the possibility to define non-square superoperators relevant for quantum circuits (by Arne Grimsmo and Josh Combes).

  • Implicit tensor product for qeye, qzero and basis (by Jake Lishman).

  • QObjEvo no longer requires Cython for string coefficient (by Eric Giguère).

  • Added marked tests for faster tests in testing.run() and made faster OpenMP benchmarking in CI (by Eric Giguère).

  • Added entropy and purity for Dicke density matrices, refactored into more general dicke_trace (by Nathan Shammah).

  • Added option for specifying resolution in Bloch.save function (by Tarun Raheja).

  • Added information related to the value of hbar in wigner and continuous_variables (by Nicolas Quesada).

  • Updated requirements for scipy 1.4 (by Eric Giguère).

  • Added previous lead developers to the qutip.about() message (by Nathan Shammah).

  • Added improvements to Qobj introducing the inv method and making the partial trace, ptrace, faster, keeping both sparse and dense methods (by Eric Giguère).

  • Allowed general callable objects to define a time-dependent Hamiltonian (by Eric Giguère).

  • Added feature so that QobjEvo no longer requires Cython for string coefficients (by Eric Giguère).

  • Updated authors list on Github and added my binder link (by Nathan Shammah).

Bug Fixes

  • Fixed PolyDataMapper construction for Bloch3d (by Sam Griffiths).

  • Fixed error checking for null matrix in essolve (by Nathan Shammah).

  • Fixed name collision for parallel propagator (by Nathan Shammah).

  • Fixed dimensional incongruence in propagator (by Nathan Shammah)

  • Fixed bug by rewriting clebsch function based on long integer fraction (by Eric Giguère).

  • Fixed bugs in QobjEvo's args depending on state and added solver tests using them (by Eric Giguère).

  • Fixed bug in sesolve calculation of average states when summing the timeslot states (by Alex Pitchford).

  • Fixed bug in steadystate solver by removing separate arguments for MKL and Scipy (by Tarun Raheja).

  • Fixed Bloch.add_ponts by setting edgecolor = None in plot_points (by Nathan Shammah).

  • Fixed error checking for null matrix in essolve solver affecting also ode2es (by Peter Kirton).

  • Removed unnecessary shebangs in .pyx and .pxd files (by Samesh Lakhotia).

  • Fixed sesolve and import of os in codegen (by Alex Pitchford).

  • Updated plot_fock_distribution by removing the offset value 0.4 in the plot (by Rajiv-B).
