Upgrade Instructions

Interface Changes

  • Violations of uncomputation rules are now flagged as errors instead of warnings.
  • The function qubit_op_to_pauli_terms in the chemistry module is deprecated due to incorrect order of qubits in its result. Please use qubit_op_to_qmod instead.

Bug Fixes

  • Resolved an issue with labeling CX gate inputs in QP visualization, so that the correct qubit labels are now displayed.
  • Fixed qfuncs being expanded declaratively (symbolically) when passed as arguments to other qfuncs.
  • Improved the error message for type errors with function arrays.
  • Fixed error message for nan values.
  • Fix mapping from output registers to measured qubits on parametrized repeat circuits with HW aware synthesis.
  • Fix phase applied with an execution parameter under multiple controls.
  • Fix unscheduled_suzuki_trotter and qdrift implementations.
  • Fix SDK function get_execution_actions
    • Flattened the cost field. The result holds now cost, currency_code
    • Add session_id in the result
  • Fix compilation of unused variables defined in nested blocks.

Studio

  • Classiq Studio now includes built-in AI integration, allowing users to generate, optimize, and execute quantum models directly within the Studio. This capability leverages Classiq's quantum resources and requires no external API tokens.
