# MQSS FAQs

## What is MQSS?

**MQSS** stands for _Munich Quantum Software Stack_, which is a project of the _Munich Quantum
Valley (MQV)_ initiative and is jointly developed by the _Leibniz Supercomputing Centre (LRZ)_ and
the Chairs for _Design Automation (CDA)_ and for _Computer Architecture and Parallel Systems (CAPS)_
at TUM. It provides a comprehensive compilation and runtime infrastructure for on-premise and remote
quantum devices, supports modern compilation and optimization techniques, and enables current and
future high-level abstractions for quantum programming.

This stack is designed to deploy in various scenarios via flexible configuration options, including
stand-alone scenarios for individual systems, cloud access to multiple devices, and tight
integration into HPC environments supporting quantum acceleration.

A concrete instance of the MQSS is deployed at the LRZ for the MQV, serving as a single access point
to all of its quantum devices via multiple compatible access paths, including 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.
