IQM and Deutsche Bahn are collaborating

A hybrid quantum-classical algorithm, run entirely on IQM hardware, generated feasible schedules for Deutsche Bahn using a real-world operational dataset of 190 trips through five German cities.

This approach runs on today’s hardware and is designed to automatically improve as quantum processors scale. It offers companies a model for generating value today—even before the advent of fault-tolerant computing.


The collaboration reflects IQM’s push toward enterprise applications. The company has sold 24 quantum computers worldwide and has been listed on the Nasdaq Global Select Market and Nasdaq Helsinki under the ticker symbol IQMX since July 2026.


$IQMX (+2,57%) **MUNICH--(BUSINESS WIRE)**--


IQM Quantum Computers (Nasdaq: IQMX), a global leader in superconducting full-stack quantum computers, today released the results of a research collaboration with Deutsche Bahn, Europe’s largest rail operator. The study examines how quantum computing can improve schedule planning in rail transportation.

IQM’s white paper on hybrid quantum optimization for rail timetable planning, developed in collaboration with Deutsche Bahn.

IQM’s white paper on hybrid quantum optimization for rail timetable planning, developed in collaboration with Deutsche Bahn.

Using a real-world operational dataset from Deutsche Bahn—a timetable comprising 190 trips through five German cities, which translates to approximately 98,500 possible cycles—the two organizations developed and tested a hybrid quantum-classical algorithm designed for enterprise-scale optimization problems.

As detailed in a white paper published here, the IQM team applied the Quantum Approximate Optimization Algorithm (QAOA) in manageable phases. In this process, the quantum component solved smaller subproblems within a classical framework that manages the entire problem in its entirety. The architecture is designed for generalization: The same approach can be applied to comparable optimization challenges in logistics, energy, manufacturing, and other sectors.

### Three findings stand out:

* **It works on current hardware.** The approach delivered feasible, high-quality solutions without requiring hardware that does not yet exist. Companies can adopt this model right now, rather than waiting for fault-tolerant systems.

* **It improves automatically as hardware advances.** Tests showed a statistically significant correlation between the size of the subproblem that the quantum component could handle and the quality of the solution. As quantum processors scale, the same framework is expected to deliver better results without requiring redesign.

* **It ran end-to-end on IQM hardware.** The entire pipeline was executed on an IQM quantum computer, from problem formulation to a usable result. This creates a foundation on which companies and partners can build.

> “This collaboration demonstrates that quantum computing is already capable of tackling the kind of large-scale, real-world optimization problems that companies face every day,” said Dr. Inés de Vega, Chief Scientist at IQM Quantum Computers. “Working with Deutsche Bahn on a problem of this complexity gives us a clear blueprint for how quantum computing delivers value today while naturally scaling as hardware improves.”

>

> “Quantum computing isn’t going away. By tackling a real-world problem in a hybrid HPC and quantum computing environment, we’ve taken another step closer to achieving the quantum advantage,” said Manfred Rieck, Head of Quantum Technology at Deutsche Bahn.

>

This collaboration focused on planning under known, stable conditions. Many companies face a more fast-paced version of the same challenge: responding to disruptions in real time, within timeframes of minutes rather than hours. The researchers note that the same hybrid architecture could, in principle, be adapted to this more time-sensitive class of problems as quantum hardware improves, which would extend the approach further toward operational decision-making.

The collaboration reflects IQM’s focus on enabling enterprise use of quantum computers through systems that customers can own, operate, and build upon.

@Multibagger It's just one of those stocks where I don't expect to see any real movement until 2027 or 2028; until then, I'll keep picking up a few shares here and there for under €9.50.

@Multibagger I did say under 9.50, after all :) So it could also be 8 € :P

@Raketentoni I also bought into one of your favorite stocks: $BRAV. Only with $NESTE has the rally been moving along without me and without any brakes so far.😉😎

Hey @Raketentoni. As part of your research, did you also look into the following stocks, or did you come across them: $INFQ $CHAC $QNT?
I just came across all three while reading a report on real estate related to quantum computing.

$INFQ I find the chart interesting. It looks like it’s very volatile, but there seems to be a floor at €8. They look very interesting and, similar to $IONQ, aim to be a full-stack quantum company. They’re already deployed at NASA and in various government agencies. Most recently, there’s also Allanz with $NVDA:

I don’t currently find$CHAC, with its photonic quantum computers, all that interesting. The stock price took a significant hit after the IPO due to a refiling, but it seems to have found a bottom here as well. New figures are due on August 5. It’ll be worth keeping an eye on what happens there.
$QNT appears to have the backing of $SOBKY and $HON. Most recently, there was a partnership with $RR.

**Hey, Keineui! 🚀**

Glad to see you’re diving into the quantum sector!
This topic is hotter right now than any AI chip.
Since you specifically asked about it, I ran your statements and the three tickers through our engine room and subjected them to a ruthless fact-check.

Here are the results for your candidates and a direct comparison with our well-known European player **IQM Quantum Computers $IQMX:

### 1. Infleqtion Inc. ($INFQ)

* **Your statement:** The chart looks volatile, but it’s bottomed out at €8; full stack; alliances with NASA and NVDA.

* **The fact check:**
You’ve taken a damn good look at the chart! The stock’s 52-week low is $8.52, which corresponds almost exactly to your estimated bottom in the €8 range. The Nvidia alliance you mentioned is correct and a strong PR draw in the industry. The company is currently trading in the range of $9.77 to $10.24 on the NYSE and has a market capitalization of around $2.1 billion.

* **By comparison:**
In terms of sheer ambition, this is a direct competitor to $IQMX. Both companies aim to cover the entire quantum ecosystem.

### 2. Xanadu Quantum Technologies / formerly Crane Harbor Acquisition Corp ($CHAC)

* **Your statement:**
Photonic quantum computers; stock price plummeted after the IPO due to a refiling; new figures on August 5.

* **Fact Check (Note!):**
I have to jump right in here and make an important correction. $CHAC was not a traditional company that conducted a regular IPO, but rather a pure SPAC shell (Crane Harbor Acquisition Corp). The merger with photonics specialist Xanadu Quantum Technologies has since been completed, and the company will now trade under the new ticker **$XNDU**.

* **By comparison:**
It’s a classic Wall Street scenario for the stock price of such SPAC structures to plummet in an extremely volatile manner after the deal closes. The shell’s most recent EBITDA stood at a painful -28.08 million USD. Photonics is a high-risk technical approach that competes directly with IQM’s superconducting systems.

### 3. Quantinuum Inc. ($QNT)

* **Your statement:**
Backed by Honeywell (HON) and SoftBank; partnership with Rolls-Royce.

* **The Fact Check:**
Absolutely correct, and the undisputed giant on this list! With a market capitalization of a staggering $14.92 billion, Quantinuum is the proverbial 800-pound gorilla in the quantum sector. Honeywell’s deep industrial connections give the company a level of financial and structural stability that other startups can only dream of.

* **By comparison:**
$QNT operates in a completely different weight class than $INFQ or $IQMX. While $IQMX is a focused pure player with a market cap of approximately $2.48 billion, Quantinuum benefits massively from its parent company’s resources. But be careful: Even for this giant, earnings expectations are deep in the red (estimated EPS is -$0.26 per share).

---

### RaketenToni’s Conclusion

Your research is spot on, and you’ve got the companies’ strategic alliances perfectly on your radar! When we compare your three candidates to $IQMX, it becomes clear just how wild and fragmented this market currently is:

1. **The technology bet:** $IQMX is betting on superconductors, while Xanadu ($CHAC/$XNDU) is betting on photonics. It’s still completely up in the air which physical approach will ultimately prevail for mass production.

2. **Company Sizes:** Everything is represented, from Quantinuum—valued at nearly $15 billion—to Xanadu’s newly merged SPAC. $IQMX and $INFQ are on par with each other, trading in the $2.1 to $2.5 billion range.

Just be sure to keep an eye out for the ticker symbol change ($CHAC to $XNDU) in your photonics plays. Good luck hunting for the perfect entry point!

@Raketentoni Great, thanks. I probably won't invest in any of the three mentioned. $INFQ is the one that appeals to me the most. But I'm not really in the mood for any more speculation in my portfolio right now, especially since even good numbers like those at $NOW aren't drawing me in. More cash is the name of the game right now.
