v1.9.0

The 1.9.0 release of the QDK includes interoperability with Qiskit circuits built upon the core Q# compiler infrastructure.

The Qiskit interop provided by the QDK includes:

• Resource estimation for their Qiskit circuits locally
• Q# Simulation of Qiskit circuits using Q#'s simulation capabilities
• QIR generation from Qiskit circuits leveraging the modern QDKs advanced code generation capabilities.

The Qiskit interop wiki page provides a brief overview of the integration while detailed examples, potential errors, and usage with parameterized circuits are demonstrated in the sample Qiskit interop notebook.

In addition to the Qiskit interop feature, the language service for Q# will now auto-suggest the new standard library API instead of the legacy Microsoft.Quantum-prefixed standard library API. For example, when typing DumpMachine, you'll now get a suggested import for Std.Diagnostics.DumpMachine instead of Microsoft.Quantum.Diagnostics.DumpMachine.
