planqc and partners win €2.3M to study quantum–classical hybrid industrial optimization
planqc, Saarland University, BMW and Infineon have launched a joint research project called “QIAPO” to address complex industrial optimization problems. The German Federal Ministry for Research, Technology and Space (BMFTR) is funding the project with €2.3 million, which will evaluate over three years a hybrid approach that reduces problems via quantum computation and then processes them with classical algorithms.
Announcement overview
QIAPO’s full name is “Quantum-Informed Approximate Optimization on NISQ and Partially Fault-Tolerant Quantum Computers.” The project targets complex optimization problems arising in areas such as automotive manufacturing and semiconductor chip production and logistics, and will use the neutral-atom quantum computer that planqc is building in Garching. Rather than using a quantum computer to solve an entire problem end to end, the approach uses quantum computation to reduce problems into forms and scales that classical computing can handle more easily, and then completes the computation with established classical algorithms. The research focuses on efficiently obtaining higher-quality approximate solutions rather than exact solutions. The original article gives an illustrative example of improving a problem solvable at roughly 80% accuracy to 85% or 95%. However, this is an illustrative example to explain the approach and not a result demonstrated by QIAPO.
Key points
- Saarland University, planqc, BMW and Infineon are collaborating on QIAPO.
- The BMFTR grant totals €2.3 million, and the research period is three years.
- The project will use the neutral-atom quantum computer planqc is building in Garching.
- The team will develop a hybrid method that reduces problems with quantum computation and obtains approximate solutions using classical algorithms.
- Quantum advantage or concrete efficiency improvements have not been demonstrated at this stage.
Technical and business implications
Technically, the approach is characterized by assigning the quantum computer the role of reducing an optimization problem to a scale and form that classical computation can handle, rather than entrusting the entire workflow to the quantum device. It is a pragmatic approach that combines NISQ and partially fault-tolerant quantum machines with existing classical algorithms. From a business perspective, even modest improvements in approximate solutions could translate into resource savings or financial impact in large-scale domains such as automotive and semiconductor production and logistics. However, the effect and any advantage from using quantum computation have not yet been shown, and comparisons with classical methods under the same conditions will be important.
What to watch
Going forward, the primary observation points will be the results run on the neutral-atom quantum computer and comparisons with classical methods applied to the same industrial problems. Key evaluation criteria will include not only solution quality but whether improvements are achieved in computation time and required computational resources, and to what extent automotive and semiconductor problems can be mapped onto quantum processing. Over the three-year study, evaluation on problems handled by BMW and Infineon should materialize and will indicate the conditions under which adding quantum computation provides benefits.
✍️ Quantum Index Analysis
For optimization problems, many quantum algorithms are iterative, involving repeated parameter tuning and circuit evaluation, so performance is not determined solely by quantum circuit execution speed. Even if FTQC is realized, if the number of search iterations does not decrease, total computation time could still be large.
In that sense, QIAPO’s design—using quantum computation to reduce problems and finishing with classical optimization—can be seen in at least two ways.
One view is a positive assessment: a pragmatic hybrid design that does not delegate the entire search for optimal solutions to the quantum computer, but instead exploits quantum strengths only where they are most likely to appear.
Another view is that, because the division of labor between classical and quantum computers can be flexibly adjusted, the approach can secure certain outcomes even if quantum-side performance is limited—in other words, it is a design that incorporates practical, risk-managing considerations for project operation and business continuity, a so‑called “grown-up convenience.”
For future evaluation, it will be important to see how much the addition of quantum processing can reduce the number of iterations or the search space itself. Not only simple circuit execution speed or qubit counts, but how much overall computational efficiency can be improved through the division of roles with classical algorithms will likely be the assessment axis that determines competitiveness.
