This 15-year-old researcher earns a doctorate by using quantum physics to extend lifespan.

In a quiet European laboratory, a teenager studies complex equations while many peers are still sitting their GCSEs.

At just 15, a young Belgian researcher has turned a classic science-fiction theme - living longer and better - into a concrete academic project, drawing on quantum physics, advanced mathematics and artificial intelligence.

A PhD at 15 that challenges the traditional academic path

The central figure in this story is Laurent Simons, a 15-year-old Belgian who has just completed a PhD in quantum physics at the University of Antwerp. His viva took place on 17 November 2025 before an official panel and is recorded in the university’s documents.

The title did not come out of nowhere. Laurent moved through milestones at record speed: he finished the equivalent of secondary school at eight and completed an undergraduate science degree in about 18 months. While childhood classmates were still learning basic algebra, he was already working in university laboratories.

Despite the pace, his journey is not only about being precocious. Laurent undertook research placements at different European centres, particularly in Germany, where he worked with theoretical and experimental physics groups. Rather than moving quickly into major tech firms, he chose to remain in academia and fundamental research.

Laurent’s case brings back an old debate: how science can support exceptionally early talent without turning research into a spectacle.

On a global comparison, it is hard to say whether he is “the youngest PhD in the world”. Education systems vary too much between countries. What verifiable records do show is that Laurent is among the youngest people to receive a PhD in Belgium, especially in a field with highly complex theory.

What this young quantum physicist studies

Laurent’s thesis focuses on a topic that is tough going for non-specialists: the behaviour of polarons in a state of matter known as a supersolid. At first glance, it sounds far removed from everyday life. But research like this helps lay the foundations for future technologies, including in medicine.

Polarons and supersolids in plain English

In physics, a polaron is, in simplified terms, a particle “dressed” by the distortions it creates in the material around it. It does not exist in isolation: it carries with it the effect it has on the medium it moves through. That changes its effective mass, its energy and how it interacts with other particles.

A supersolid is even more exotic. It combines two features that rarely appear together:

• an ordered structure, like an ordinary crystal;
• the ability to flow without friction, like a superfluid.

In his thesis, Laurent studied the behaviour of a single “impurity” - a foreign element introduced into a medium - inside a dipolar Bose–Einstein condensate. This system exists only at extremely low temperatures, close to absolute zero, when atoms begin to behave collectively in a quantum way.

To model the problem, he used an advanced mathematical tool called the path integral. This approach allows one to sum, in a controlled way, all possible quantum paths of the particle, calculating how the impurity deforms the medium and how that deformation feeds back to affect the particle itself.

The results help explain how a small disturbance can modify an entire system - an idea that appears in both materials physics and complex biological models.

These simulations can refine experimental techniques such as high-precision spectroscopy, used to measure energy levels and interactions in quantum systems. The work was made available on a scientific preprint platform, allowing other groups to carry out independent checks.

From the quantum lab to the human body: the plan to extend healthy life

Soon after completing his PhD in Antwerp, Laurent moved to Munich in Germany to begin a second doctorate, this time in medical sciences. The current focus is closer to everyday concerns: analysing biological signals with the help of AI to detect disease earlier and design more personalised treatments.

AI, biology and physics working together

Rather than being drawn in by offers from major tech companies - including in the United States and China - he chose to stay with academic groups that work directly with hospitals and biomedical research centres.

The long-term project combines three pillars:

• Physics: models to describe complex systems, such as neural networks or protein dynamics;
• Biology and medicine: collection of cardiac, brain and metabolic signals from real patients;
• Artificial intelligence: algorithms able to spot subtle patterns that the human eye would miss.

The stated goal is not to make anyone immortal, but to extend the healthy span of life, reducing the years lived with chronic pain, severe limitation or dependence on others. That means earlier diagnosis, more precise intervention and continuous monitoring of a patient’s progress.

In Laurent’s project, a long life means more years with independence, not simply more days added to the calendar.

To do this, he takes part in collaborations with biologists, condensed-matter physicists and AI specialists. The team emphasises rigorous practice: properly anonymised data, clear protocols and studies that other groups can replicate.

How highly theoretical research could affect your health in future

The link between polarons in supersolids and longevity can feel remote. But the history of science shows that many of today’s medical technologies began as purely theoretical problems. MRI, for instance, depends on advances in quantum mechanics and nuclear physics developed decades before any clinical use.

Work like Laurent’s provides tools for understanding complex systems that respond non-linearly to small disturbances. The human body is a good example: a tiny change in a protein, a neural circuit or a gene can cascade and lead to serious disease years later.

In future scenarios, mathematical models inspired by quantum physics and exotic states of matter could help to:

• predict tumour progression more accurately;
• simulate how new medicines interact with specific tissues;
• create ultra-sensitive biomedical sensors to detect microscopic changes in real time;
• optimise the use of AI in diagnosis, reducing false positives and false negatives.

Terms worth a quick explanation

Term	Meaning in plain language
Bose–Einstein condensate	A state of matter at very low temperatures in which many atoms behave as if they were a single “super-particle”.
Superfluid	A fluid that flows without friction, without losing energy - something impossible in ordinary liquids.
Path integral	A mathematical method that accounts for every possible path a particle could take to calculate quantum probabilities.
Biological signal	Any measurement from the body: heart rate, the brain’s electrical activity, glucose levels, and so on.

Risks, limits and possible scenarios in the search for longevity

Projects that promise longer lives often attract a lot of money - and, with it, exaggeration. The presence of a young prodigy draws media attention but also brings risks: pressure for quick results, expectations of magic solutions, and misuse of his image to sell products with no scientific basis.

A realistic possibility is that some of the AI techniques developed by Laurent and colleagues will first reach specific areas, such as cardiology and neurology, as clinical decision-support tools. They could help doctors notice risk patterns in test results before any obvious symptoms appear.

On the other hand, intensive use of biological data raises debates about privacy, unequal access to treatment, and over-reliance on algorithms. Decisions about whether to begin aggressive treatment based on mathematical models require transparency and rigorous validation.

For outside observers, Laurent’s trajectory becomes a different kind of live laboratory: how societies handle early talent, expectations about longevity, and scientific responsibility. The balance between the dream of living longer and the patience of slow, careful research will be tested many times before concrete results make it into the GP surgery or hospital clinic.
