General information on the Euro-Q-Exa user operation

Overview

After having operated the Euro-Q-Exa system at LRZ during the Friendly User Pilot Phase in spring 2026, we want to transition to the regular user operation of the system.  In the following, the main parameters for its operation are described. Academic users from Germany can apply directly with us, whereas users from the EU or industrial users from Germany can follow the EU access path linked below.

EU access path

Users from outside Germany and German companies without a collaboration partner from academia can apply via the EuroHPC access calls:

https://access.eurohpc-ju.europa.eu/

Users of the system and access model

Every researcher with a scientific affiliation in a German institution is entitled to access the Euro-Q-Exa system. German companies can apply for using Euro-Q-Exa, within research project where public research institutions are involved as partners. The researchers can start submitting their project proposals immediately, the access to the system will be granted starting from August 2026.

We ask the researchers to fill our proposal template, to be downloaded here: LRZ project proposal template. The proposal will get a scientific review, by a researcher selected from an internal pool, and technical review done by the LRZ team. The scientific review assesses the objective of the proposal, its soundness and the expected impact in its research area, you want to address, whereas the technical review judges on the feasibility of the proposal, given the hardware constraints and proposed timeline. Based on the recommendations of the reviews, a fraction up to 100% of the requested computing resources will be assigned to the project. This budget can be consumed by any of the users associated to the project.

In the start-up phase of the Euro-Q-Exa regular user operation, and until a reviewing process is established, only the technical review will be performed, and the users will get 100% of the proposed computing resources.

The researchers who got access during the Friendly User Pilot Phase keep their access granted, but they are asked to fill and submit the proposal template as well, by September 30th. They may use the same data as in the proposal or final report of the Friendly User Pilot Phase, provided these are still relevant to the research planned during regular user operation.

The duration of each project is set to one year, with the possibility of applying for extensions, by submitting the one-year final report and providing justification. A graphics representing the user journey in applying to system access and using it is reported below.

Communication plan

Mailing list

Each user will have his/her email address added to the mailing list qc-users@lists.lrz.de. This mailing list is used to communications on the status and operation of the system. Other list members are not enabled to send messages to the list.

Element room

This was a valuable resource during the Friendly User Pilot Phase, but it does not scale with a larger number of users expected during the regular user operation and therefore it will be closed. The incident and user requests will be managed through a ticketing system (see below).

LRZ Solution Architects and project mentoring

The collaboration between the test users and the LRZ Solution Architects cannot be extended to all users during the regular operation, because of the obvious limitations in manpower. However, the users can apply in their project proposal for dedicated support and justify their request. The LRZ team, within the available personnel resources, will be happy to engage with the community. A standard level of support is guaranteed through our Incident and Service Request Management system (see below).

User Support and Request Mechanisms

As LRZ transitions from the testing phase into regular operation of its quantum systems, the support structure for users are being updated. Below you will find the available mechanisms for reaching the LRZ Quantum Computing and Technologies (QCT) team.

• LRZ Servicedesk

The LRZ Servicedesk remains the primary contact point for all general inquiries, incident reports, and service requests related to LRZ systems:
https://servicedesk.lrz.de/en

The Servicedesk offers an easy-to-use web interface for submitting tickets. Requests are automatically routed to the appropriate specialists within LRZ, helping ensure fast and reliable processing and avoiding delays (e.g., due to staff absences). To reach the Quantum Computing team via the Servicedesk:

Select “Consulting Quantum Computing” as the service or use the direct “Simple Submit” link https://servicedesk.lrz.de/en/simplesubmit/164

This channel is suitable for all users and recommended for anyone who does not wish to use GitHub for communication.

• MQSS Contact and Request Mechanism

To better support Munich Quantum Software Stack (MQSS) users and align with modern development workflows, the LRZ QIS team has introduced a new request mechanism for the MQSS.

A dedicated GitHub profile is available at: https://github.com/Munich-Quantum-Software-Stack

If you want to request a new feature, ask a question, or report a bug to the MQSS team, please use these issue templates of the Benchmarking Framework or Munich Quantum Portal components.

Each submission creates a GitHub issue within the relevant MQSS repository and ensures structured communication with the responsible developers.

Note: A GitHub account is required. Users who do not have or prefer not to use one (e.g., for GDPR considerations) can continue using the LRZ Servicedesk.

This GitHub-based workflow will be expanded to include additional MQSS components. 

Software environment and other resources

After getting the LRZ ID, the users will be able to access the Munich Quantum Portal at the address https://portal.quantum.lrz.de/ . Under “Status”, the “Introduction to the software stack” is a valuable resource to familiarise with the QC environment at LRZ.

Documentation of the MQSS Qiskit adapter can be found here:

https://munich-quantum-software-stack.github.io/MQSS-Interfaces/qiskit/index.html

The Qiskit Adapter is part of the MQSS Interfaces, documented here: https://munich-quantum-software-stack.github.io/MQSS-Interfaces/

On the hardware side, the system specifications for the Euro-Q-Exa system are here: https://meetiqm.com/products/iqm-radiance/  

The documentation for running Variational Quantum Algorithms (VQAs) on the system will be prepared soon and located in these pages.
