What is MQSS?

MQSS stands for Munich Quantum Software Stack and is a project of the Munich Quantum Valley (MQV) initiative. It is jointly developed by the Leibniz Supercomputing Centre (LRZ), the Chair for Design Automation (CDA), and the Chair of Computer Architecture and Parallel Systems (CAPS) at TUM. It provides a comprehensive compilation and runtime infrastructure for on-premise and remote quantum devices, support for modern compilation and optimization techniques, and enables both current and future high-level abstractions for quantum programming. This stack is designed to be capable of deployment in a variety of scenarios via flexible configuration options. This includes stand-alone scenarios for individual systems, cloud access to a variety of devices, as well as tight integration into HPC environments supporting quantum acceleration. Within the MQV, a concrete instance of the MQSS is deployed at the LRZ, serving as a single access point to all of its quantum devices via multiple compatible access paths. This includes a web portal, command line access via web credentials, as well as the option for hybrid access with tight integration with LRZ's HPC systems. It facilitates the connection between end-users and quantum computing platforms by its integration within HPC infrastructures, such as those found at the LRZ.

What is QDMI?

QDMI, or Quantum Device Management Interface, serves as the communication interface between software within the MQSS and the quantum hardware connected to the MQSS. The aim is to provide a standard way to communicate with quantum resources that can be widely used by the quantum community.

What is a QDMI Device?

QDMI Device, or QDMI Backend, is a QDMI implementation of a quantum device that enables QDMI clients to interact with hardware though QDMI drivers. The hardware can vary from quantum emulators to neutral atom quantum computers.
