Overview

This release adds some quality-of-life functions, mostly to the benefit of larger software stacks which integrate QuEST. It also includes some bug patches and internal software architectural clean-ups, primarily by @rrmeister.

New features

  • setDensityAmps() allowing direct modification of the amplitudes of a density matrix.
  • copySubstateToGPU() allowing partial overwriting of a statevector in GPU memory
  • copySubstateFromGPU() allowing partial loading of a GPU statevector into accessible memory
  • mixNonTPKrausMap() to simulate Kraus maps which are not necessarily trace-preserving

Other changes

  • Updated the Bernstein-Vazirani demo to simulate more analogously to the experimental method
  • Updated demo codes to use precision-agnostic string formatters
  • Improved CMake build (f8747ca)
  • Improved the internal validation architecture

Bug fixes

  • patched rare distributed bug in calcTotalProb() of density matrices (#326)
  • patched rare GPU build bug in applyPhaseFunc()
  • patched rare memory leak during failed validation of Qureg and DiagonalOp validation
  • patched GPU build flags (512966a)
  • patched invalidQuESTInputError() build problem on Windows (#314)
  • patched build warnings related to precision of internal non-simulation functions (fc25c34)
