0.20.0

Upgrade Instructions

• Python SDK
• VS Code Extension - deprecated. Use IDE instead.

Interface Changes

1. Remove num_qubits attribute from StatePreparation and add it to GaussianMixture.

Enhancements

1. Add error metrics for StatePreparation: total variation, Hellinger, and Bhattacharyya. See StatePreparation.
2. Add a new function: ComputationalStatePreparation. See ComputationalBasisStatePreparation.
3. Add a new function: GHZStatePreparation. See GHZStatePreparation.
4. Add a new execution building block: the Operators' Estimator.
5. Change the AmplitudeEstimation parameters to GroverOperator and estimation_register_size. See AmplitudeEstimation.

IDE Improvements

1. Automatic Registers Resolution: Automatically label, color, and merge (when possible) individual qubits according to their associated registers. See Automatic Registers Resolution.
