0.18.0

Upgrade Instructions

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

Interface Changes

1. Support visualization of empty (0) and non-empty (1) control qubit, thus supporting every classical string as control state. See details on control states: MCX gate.

2. Add optional user-defined timeout for the optimization stage of synthesis. See Optimization Timeout.

3. Modify default two-qubit basis gate list. See information on basis gates for synthesis: Hardware Aware Synthesis.

4. Add update_problem method for GroundStateProblem. Use it before defining chemical ansatzes. See Chemistry.

5. Change the production of static image of the generated circuit so it is no longer created by default. To draw the circuit, set the draw_image field of the synthesis preferences to True.

6. Change the interface of Explicit Qubit Release in the Python SDK:

   • Deprecate explicit declaration of zero inputs.
   • Declare zero outputs via the release_qregs method.

New Features

1. Add quantum phase estimation as a new built-in function. See PhaseEstimation.
2. New toolbox in application quantum circuit view: See Analyzer Web Application.
