Classiq 0.80.0

Released on 2025-05-19.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Enhancements

1. Value range analysis of arithmetic expressions is now generalized to apply
   across statements, optimizing quantum variables sizes and arithmetic expressions
   implementation in more cases.

2. Quantum functions inside a control statement get a c- prefix

3. Added the functions prepare_dicke_state and prepare_dicke_state_unary_input.

4. A new exponentiation function, sparse_suzuki_trotter,
   has been added to the core library, performing Suzuki-Trotter decomposition using a sparse representation
   of the Hamiltonian. It is recommended to use this function instead of suzuki_trotter when you handle a sparse Hamiltonian, as it is more efficient.

5. Include classiq.execution in the top level classiq package in the SDK.

   Old:

   from classiq.execution import ExecutionPreferences
   

   New:

   from classiq import ExecutionPreferences
   

6. allocate now
   supports specifying numeric attributes of the allocated variable.

Classiq 0.79.1

Released on 2025-05-15.

   resources" message.
2. Fix a bug related to execution parameters.

Enhancements

1. Value range analysis of arithmetic expressions is now generalized to apply
   across statements, optimizing quantum variables sizes and arithmetic expressions
   implementation in more cases.

Classiq 0.78.0

Released on 2025-05-05.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Enhancements

1. A new IQAE application has been added to the SDK. It allows you to define iqae problems in terms of Qmod function,
   and directly estimate the amplitude of the state you prepared.

   IQAE application Descriptions

   It is recommended to use this application in iqae problems, rather than cmain
   with the primitive iqae.

Bug Fixes

1. Fixed an issue where the “Basic” view was always empty; it now correctly renders the circuit as intended.
2. Fixed bugs causing several example models to not be supported in the "New" circuit visualization, including "Shor's Algorithm Modular Exponentiation".

Classiq 0.77.0

Released on 2025-04-28.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Enhancements

1. In Qmod's Python embedding, you can now declare quantum functions with classical parameters
   of Python builtin types such as int, float, and list. These variables can be
   used in expressions that require Python values, such as Python for loops and 3rd party
   library functions, as is shown in the example below. See more on this under the new
   reference page on
   Generative Descriptions

   @qfunc
   def rotate(ratio: float, qa: QArray[QBit]):
       for i in range(qa.len):  # 'qa.len' is a Python integer
           PHASE(math.asin(ratio * i), qa[i])  # 'ratio*2' evaluates to a Python float

Interface Changes

1. With Enhancement 1 described above, Python-type parameters supersede classical Qmod-type parameters
   in generative functions. Hence, the use of the function decorator @qfunc(generative=True)
   is no longer required. Qmod-type parameters are treated symbolically in Python, and their
   use in Python expressions is deprecated.

Classiq IDE

1. Improved UX in Quantum program visualization: collapsing a Quantum operation block will scroll the viewport into the parent operation block position

Classiq 0.76.0

Released on 2025-04-21.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Enhancements

1. It is now legal to out-of-place assign
   to a variable whose declared size is larger than the minimal size required to
   fit the range of possible expression values.

Interface Changes

1. The function synthesize now returns an object of type QuantumProgram, and its fields can be accessed directly.
   The type SerailizedQuantumProgram and method QuantumProgram.get_qprog are no longer needed, they are deprecated and will be removed in a future version.

2. Email Service Update - We've replaced the Community button with a new
   dropdown menu.
   Users can now select "Contact Us", which opens a form.
   Once the form is submitted with user details, an email is sent directly to Classiq.

3. Layout Fixes - Resolved an issue with inconsistent padding across the layout to ensure a cleaner, more polished UI.

4. Enhanced Sharing Options - In addition to existing platforms, users can now share content to LinkedIn and Reddit with a single click.

Classiq 0.75.0

Released on 2025-04-08.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Classiq Studio Updates

Added a new command reset-user-env to reset the virtual environment to its default state
helping resolve dependency issues and clean up installations.

Classiq IDE

Added a "User Terms" button inside the IDE website at the bottom of the screen, and clicking on it opens a modal displaying our user terms.

Enhancements

When estimating using the ClassiqSimulatorBackendNames.SIMULATOR_STATEVECTOR backend,
whether using the ExecutionSession or classical main, compute the expectation
value directly from the state vector instead of running shots.

Classiq 0.74.0

Released on 2025-03-31.

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

Interface Changes

1. The functions construct_qsvm_model, construct_finance_model, and
   construct_grover_model have been removed from the SDK.
   Check out our Qmod implementations of the QSVM, finance, and Grover
   algorithms on the Classiq library.

Enhancements

• QuantumProgram objects have been optimized to be significantly leaner, improving performance across all actions that handle them.
• Visualizing Quantum Programs is now significantly faster.

Quantum Program Visualization

• Auto-expand QMOD statements without expressions (e.g. power).
  
• Statements with quantum expressions now display their corresponding expression directly on the block.
