100 Years of Quantum Mechanics
And what does METAVITAL have to do with it

The United Nations has declared 2025 the International Year of Quantum Science and Technology. The occasion was an anniversary: a hundred years earlier, Werner Heisenberg had laid a decisive foundation for modern quantum mechanics with his 1925 paper. In the years that followed, physics in this field developed at a rapid pace. [1, 2]
What seemed like a fairly abstract matter at the time is something we encounter in many places today. Quantum mechanics explains properties of matter and light that our digital technology is also based on. So you don't need to work in a research lab to benefit from its applications. [3]
From Physics to Application
Quantum Physics You Can Touch
The 2025 Nobel Prize in Physics also went to findings from quantum mechanics. John Clarke, Michel H. Devoret, and John M. Martinis were honored for demonstrating macroscopic quantum tunneling and quantized energy levels in an electrical circuit. What made this special: a system made up of a very large number of particles displayed shared quantum mechanical behavior. [3]
It's not quite as simple as observing this effect on your kitchen table, though. The experiments used superconducting circuits and carefully controlled conditions. Still, they impressively show that quantum physics is not limited to individual particles. [3]
But here at METAVITAL, we're interested above all in what this physics has to do with medicine, biological processes, and our systems. So let's take a closer look.
Quantum Physics in Medicine
It's clear that modern medical equipment would look quite different without the insights of quantum physics. Just think of X-ray machines, MRI scanners, or lasers. Each of these relies on a different physical principle; "quantum physics" is not a single, unified mechanism behind all these devices.
Magnetic resonance imaging is a particularly vivid example. Magnetic fields and radio waves influence the hydrogen nuclei in the body. The signals captured afterward can be processed into images. The measurement is thus closely tied to a well-defined physical quantity and a verifiable procedure. [4]
And at METAVITAL
With METAVITAL systems, this connection isn't immediately obvious. Even notebooks, electronics, and sensors rely on components whose properties can only be fully understood through quantum physics. The same applies to many other electronic devices. The decisive point for METAVITAL, however, is the MNLS method itself.
METAVITAL describes MNLS as "Multidimensional Non-Linear Spectrography." In the company's explanatory model, biological signal patterns and their comparison with stored reference patterns, known as etalons, are central. The software is intended to derive indications of regulatory processes from these. This is how the manufacturer presents the method. [5]
A careful distinction is worthwhile here: the physical principles behind electronic components do not, by themselves, show whether a particular method can reliably detect diseases. That requires studies on the specific system, traceable measurement data, and comparisons with recognized diagnostic procedures.
METAVITAL itself classifies the MNLS method as complementary and alternative medicine and points out that the effects described are not scientifically recognized. The method does not replace medical diagnosis or treatment. [5]
What Biophotons Are
The Body's Faint Light
In connection with MNLS, biophotons are frequently mentioned. At first, this may sound unusual. In research, the term refers to light quanta of biological origin, in particular the ultraweak photon emission of living systems. The human body also emits such light – so faint that our eyes cannot perceive it. [6]
In 2009, Kobayashi and colleagues were able to capture this emission using a highly sensitive, cooled camera. Five healthy young men were examined; the measured light emission changed over the course of the day. As an explanation, the authors discussed metabolic processes in which excited molecules form and release light. The images differed from thermal images. [6]
This is an interesting finding. However, it does not yet mean that every organ has a clearly identifiable light signature or that a disease can be directly read from it. The study examined neither an MNLS device nor its diagnostic reliability. [6]
Wave and Particle
Well – here we find ourselves in the realm of quantum mechanics. Depending on the experiment, light displays properties that we describe either as waves or as individual light quanta. Physicists speak of wave-particle duality. These are different ways of approaching the same phenomenon, not two independent types of radiation.
The word "biophoton" likewise does not denote a special particle with its own laws of nature. It refers to the biological origin of the light. For detecting it, perfectly ordinary questions of measurement technology remain decisive: How sensitive is the detector? How is stray light excluded? And how well can signal and noise be separated?
Information Needs a Carrier
According to the METAVITAL model, information is at the center of the MNLS method. This can be understood as a question: what conclusions can a recorded pattern allow about the biological process? "Information" here does not mean "without energy." Every photon has energy, the magnitude of which depends on its frequency. [5, 7]
Measuring and Understanding
Measuring a signal and understanding its meaning are two different tasks.
Measuring a signal and understanding its meaning are two different tasks. Even a highly sensitive sensor does not, on its own, answer the question of where a signal comes from or what biological cause it has. For that, measurement methods, analysis, and interpretation must all fit together.
A comparison helps: a microphone can pick up a faint noise. Whether it comes from a particular engine and indicates a fault only becomes clear through further knowledge and testing. A similarly careful approach is needed when conclusions about the body are to be drawn from weak biological signals.
Staying Open and Looking Closely
The idea of viewing biological processes from the perspective of information and interaction is fascinating. On its own, however, this does not establish any connection to string theory. Similarities with holistic concepts are, for now, merely conceptual parallels and not physical proof of a method’s validity.
So what does METAVITAL have to do with a hundred years of quantum mechanics? One direct connection lies in the electronic technology used. Another lies in the questions surrounding light, biological signals, and their interpretation. How far these can justify concrete medical applications must be examined for each specific method. That is precisely why it is worth staying curious and asking precise questions.
