Getting started with QAT

The Quantum Assembly Toolkit (QAT) is OQC’s open source package that primarily aids with two aspects:

1. Compile: Compiling quantum source programs into native code that can be executed on actual quantum hardware.

2. Execute: Runtime of quantum programs to assist with execution, interpretation and results post-processing.

It also contains utility for simulation (typically used for testing purposes), such as an adapter to Qiskit’s AerSimulator and our realistic (but limited) real time chip simulator.
