0.42.0

​

Upgrade Instructions

• Python SDK
• The IDE upgrades automatically.

​

Bug Fixes

1. Fixed an error related to the translation of certain circuits between synthesis and execution.
2. Fixed an error when calling a function with local variables multiple times.

​

Enhancements

1. HHL workshop was added to the public repository and to the User Guide.
2. It is now possible to use the execution primitives estimate and vqe with models with multiple output ports. The hamiltonian should match all the output ports by their order.
3. Amplitude encoding assignments (ind *= foo(n)) support all quantum numeric variables, not only unsigned fractions.
4. Add support for lookup tables in amplitude encoding assignments, e.g., ind *= [0, 0.5, 0.5, 1][n] where n is an unsigned quantum integer (ind *= subscript([0, 0.5, 0.5, 1], n) in the SDK).
5. A quantum COSINE and SINE transforms of types I and II were added to the open library, see Quantum COSINE and SINE Transforms.
6. New algorithm was added to the library: “Variational Quantum Linear Solver (VQLS) with Linear Combination of Unitaries (LCU) Block Encoding”

7. Alice & Bob provider is now accessible.

​

Interface Changes

1. compute_qaoa_initial_point is now exposed in the SDK directly from classiq package. from classiq import compute_qaoa_initial_point
2. The examples in IDE Flow page are replaced with a new arithmetics example.

​

Bug Fixes

1. Properly evaluate type attributes in main.
   • Native Qmod: qnum’s sign field can be specified with lowercase true/false in main’s signature.
2. Fix execution results received from running on Amazon Braket to be correct when the measured outputs are not all of the variables of the model.
3. Improve language error reporting.

​

IDE

1. Uniform drawer width for all pages
2. New way to trigger node options context menu on Graphical Model page: node options menu can now be triggered by right-clicking a selected node
