Quantum computing in practice – QKI for assisted COVID-19 reporting and decision support

Quantum computing in practice - QKI for assisted COVID-19 reporting
and decision support

(December 15, 2021/Munich) At today’s network conference with the topic “Quantum computing in practice: industry-specific use cases”, Dr. Sigrid Auweter from Smart Reporting GmbH and Leo Sünkel from QAR-Lab were guests at Bayern Innovativ. The use of AI and quantum computing creates new possibilities in a wide variety of application areas – including the medical field. Smart Reporting GmbH has the goal of optimizing radiological diagnostic procedures and their reporting. For this purpose, Smart Reporting GmbH, together with the Fraunhofer Institute and the QAR-Lab of LMU Munich, are working on the use case “QKI-supported diagnosis of COVID-19 in radiology images” as part of the PlanQK project. The basic idea is to use quantum computing to analyze radiological diagnostic data and images of the lungs and surrounding organs in relation to the diagnosis of Covid-19.

The goal of this use case is to automatically classify lung CT images into three categories: Healthy, COVID 19 pneumonia, and other diagnosis. In addition, the severity in COVID19 pneumonia is determined, i.e., how intensely the lungs have been attacked by COVID19. Based on this, the best treatment option for the patient should subsequently be derived. With the help of Quantum Machine Learning, the entire process will be optimized.

 „First of all, the goal is to search and identify different solution approaches – especially related to quantum computers of the next years respectively the NISQ era.”

Quote Leo Sünkel/QAR-Lab

Several prototypes already exist that can be used to implement the project. One approach lies in hybrid classical “quantum transfer learning” with final localization of the image regions most likely to indicate pathology. This is performed on the quantum gate model. Another solution approach runs on the Quantum Boltzmann Machine which is calculated using quantum annealers.

One of the current challenges is that present quantum computers with the small number of qubits are not yet suitable to process whole CT scans on their own. For this reason, the hybrid approach is currently being forced, in which classical computers work together with quantum computers to do calculations and different architectures are being experimented with. The long-term goal is to maximize the quantum component and so achieve better results.

In the further course of the project, the various architectures will be evaluated and assessed. What are the weaknesses of the used quantum models and how good are the obtained results? On this basis, the models can be improved and extended. In addition, the newest medical findings from the COVID19 pandemic research are continuously integrated into the project.

If the use case “QKI-assisted diagnosis of COVID-19 in radiology images” succeeds in obtaining meaningful diagnoses, QKI methods can also be applied to other disease patterns in the long term and be a significant support to the healthcare sector.

Merck to Lead BAIQO Quantum Computing Project Funded by the German Federal Ministry of Education and Research – QAR-Lab at LMU will be their partner

• The QAR-Lab at Ludwig-Maximilians University in Munich, Germany, is a partner in this joint project
• Partners want to use quantum computing models to optimize clinical studies

(Darmstadt und Munich – Germany, December 9, 2021)
Merck, a leading science and technology company, today announced its membership of the research project BAIQO (Bayesian Network Analysis and Inference via Quantum-assisted Optimization), which is being funded by the German Federal Ministry of Education and Research (BMBF). This three-year project will be carried out in collaboration with the Quantum Applications & Research Laboratory (QAR-Lab) at Ludwig-Maximilians University in Munich (LMU), Germany. This research project focuses on creating a basis for the use of quantum computing in the modeling of clinical studies. Together, the partners will investigate the potentials of various quantum algorithms for optimizing models generated with the aid of machine learning from large data sets.

“The algorithms are to be integrated into our existing optimization platform and investigated. Together, we are approaching the topic of how drug candidates can move through clinical development more purposefully, more quickly, more safely, and of course, more sustainably,” said Thomas Ehmer, project manager on the Merck side. “Of course, BAIQO offers the potential for new innovative jobs in this technology field.”

Informatics Professor and Institute Chair Claudia Linnhoff-Popien, who heads the QAR-Lab at LMU, is convinced by the BAIQO project: “We at the QAR-Lab see enormous application potential for quantum computing in the optimization of clinical trials. With our many years of expertise in the areas of artificial intelligence and quantum computing, we want to support Merck in the development and implementation of beneficial algorithms.”

Machine-derived models for clinical studies (known as Bayesian models) are often highly complex, with a very large number of variables and dependencies between those variables. The research partners want to evaluate the extent to which these kinds of models can generally be translated into optimization problems to define the best possible parameter distribution for modeling successful clinical trials.

A further question that the BAIQO project aims to answer is the extent to which different kinds of quantum algorithms can be applied under the existing limitations of current quantum computing hardware, i.e. so-called NISQ devices (NISQ: noisy intermediate-scale quantum). The evaluation of currently available NISQ devices will also clarify whether a “quantum advantage” exists compared with classic approaches for optimizing clinical trials.

The BMBF will fund 73.3% of the € 1.5 million project volume via the “Application Network for Quantum Computing” funding announcement, a measure for implementing the government program “Quantum Technologies – From basic research to market”.

Quantum computing in practice: specific use cases in industry

On December 15, our partner Bayern Innovativ will bring together experts to promote an exchange of knowledge in the field of quantum computing. Branch-specific use cases are to show in which areas the technology can be applied. QAR-Lab will also present a use case with one of its partners, the Smart Reporting GmbH.

Smart Reporting GmbH has recently developed SmartCAD | COVID-19, a system for AI-supported radiological diagnosis and standardized reporting of COVID-19. This system can be significantly improved with methods of QKI and will be additionally supplemented with a QKI-based decision support in the PlanQK project.

The presentation “QKI-supported diagnosis of COVID-19 in radiology images” by Leo Sünkel – PhD student at the Chair of Mobile and Distributed Systems of the QAR Lab, LMU Munich – and by Dr. Sigrid Auweter – VP Research & Innovation, Smart Reporting GmbH, Munich – can be auditioned at 11:10 a.m..
