Upgrade Instructions

​
Enhancements

  • Concatenations can now also be used as control expressions.
  • Lower model creation and synthesis run times for large models.

​
Bug Fixes

  • Classical if statements are now supported in QP visualization, where they previously caused a failure.
  • Fix synthesis bug which caused wrong results when using the bitwise invert (~) operator.
  • Fix bug relating to classical struct arguments (such as Hamiltonians).
  • Use the Solovay-Kitaev algorithm in more cases when transpiling. Previously, we used the algorithm when transpiling with respect to a particular fixed set of basis gates. Now, we use this algorithm whenever the basis gate set contains the Clifford gates X, Z, H, T, and CX but does not contain arbitrary-angle rotation gates such as RX or CRZ.

Classiq IDE

  1. Add mechanism to allow more models to be visualized in new visualization.

  2. ​
    Visualization: Data Tab Removal

The Data tab has been removed from the left panel in the visualization interface. This change is removing redundant functionality.

  1. ​
    Deprecation: QP Visualization Basic View Mode

Deprecated “Basic” mode quantum program visualization in favor of the new visualization scheme with enhanced designs, views, and analysis capabilities.
The search panel focuses only on user written functions and QMOD statements.
