Add support for Intel® Quantum SDK: https://www.intel.com/content/www/us/en/developer/tools/quantum-sdk/overview.html

Primarily written in C++, but includes a convenient Python wrapper with compatibility with OpenQASM 2.0:

================================================================================
                Intel(R) Quantum SDK - v1.0 Release Notes
================================================================================

Addition of Quantum Dot Simulator Backend
* The Intel(R) Quantum SDK supports a new target backend for the full-stack in
  simulation. This is a physics-based simulation of quantum dot qubits as well
  as simulation of control electronics. 

Addition of Placement and Scheduler passes
* The Intel(R) Quantum SDK now provides automatic mapping and scheduling of
  quantum algorithms onto qubits. These passes treat the problem of mapping
  variables of type qbit onto the qubits as a physical resource and take into
  account the connectivity between qubits.

Added support for OpenQASM 2.0
* The Intel(R) Quantum SDK provides a source-to-source translator module that
  enables users to directly use programs that they have written to output
  OpenQASM 2.0.

Added an interface to Python
* The Intel(R) Quantum SDK supports interacting with the Python parts of the
  quantum computing eco-system through a choice of writing OpenQASM 2.0 and
  compiling it or by compiling your own shared object.

also, already seems to integrate with qiskit-terra \ ProjectQ
