Upgrade Instructions

Enhancements

  • Concatenations can now also be used as control expressions.
  • Added the functions lcu and lcu_pauli for creating the Linear Combination of Unitaries primitive (LCU).
  • IBM Cloud is now available. See Cloud Providers section in the user guide.
  • The default optimization level in the synthesis preferences has been changed from OptimizationLevel.HIGH (3) to OptimizationLevel.LIGHT (1). For more information about optimization level see the optimization level section in the user guide.

Fixes

Bug Fixes

  • Fix a synthesis bug that causes, in some cases, the function under power to have a separate power for each function, instead of sharing it as a whole.
  • Fix a failure in hardware-aware synthesis of parametric models for the Azure Quantum provider.
  • Fix a bug in get_hf_state when using qubit tapering.

Visualization

Introducing "Variables View"

A new compact visualization mode that displays quantum variable flow at a higher level perspective. Toggle between this streamlined view and the traditional qubit grid overlay using the Variables View switch in the visualization menu bar.”

Classiq Studio

Memory monitor

A new memory monitoring feature that tracks and displays resource usage during Classiq Studio Usage, providing real-time insights into memory consumption patterns. plot
