ULM – German scientists have announced a discovery that could fundamentally change the future of quantum computers. They have developed a special organic molecule that could enable the production of quantum chips using processes similar to those used in the manufacture of smartphone displays. The research results were published on October 28 in the prestigious scientific journal Nature. The new technology promises simpler and potentially cheaper production of computers, whose capabilities could significantly surpass current computing technology.
Quantum computers are among the most promising technologies of the present day. Scientists expect that in the future, they could help in the development of new drugs, the discovery of advanced materials, or the solution of extremely complex mathematical problems. However, their wider use is currently hindered by high costs, technological complexity, and difficulties in manufacturing sufficiently powerful and reliable processors.
The discovery by the German technology company NVision, based in Ulm, could help overcome one of these obstacles.
Quantum chip similar to a phone display
The basis of the new technology is a specially designed organic molecule that can function as a so-called qubit, which is the basic unit of quantum information.
Unlike a conventional computer bit, which takes on a value of zero or one, a qubit can also be in a superposition of states due to the properties of quantum mechanics. It is precisely this property, in combination with other quantum phenomena, that enables certain calculations that classical computers cannot effectively replicate.
Scientists at NVision have developed a molecule whose quantum state can be individually controlled and detected using microwave radiation and light.
A key advantage is the possibility of using these molecules in thin organic layers applied to photonic chips. Similar technologies for applying organic materials are already used in industry, for example, in the manufacture of OLED displays for smartphones and televisions.
If this process can be translated into industrial practice, it could significantly simplify the production of quantum processors, which today often requires highly specialized equipment and expensive manufacturing processes.
Artificial intelligence also helped in the discovery
The way in which the scientists arrived at their discovery is itself interesting. Researchers used computer modeling and artificial intelligence to test hundreds of possible molecular structures.
During several years of research, they subsequently prepared more than 40 candidate molecules in the laboratory before finding one that met the necessary requirements.
A key role was played by a molecule from the group of so-called carbenes. Its electronic properties allow it to store quantum information and simultaneously connect it to light particles, i.e., photons.
The use of photons is important for the future interconnection of a larger number of quantum units. Instead of a single, extremely complex processor, systems could be created consisting of multiple interconnected quantum chips.
Experiments have shown that scientists can prepare, control, and optically read the quantum state of individual molecules. Under suitable conditions, it was possible to maintain its quantum coherence for up to 2.2 milliseconds.
Although this is a very short time interval, it represents a significant result from the perspective of quantum operations.
The technology originated in cancer research
The research itself has a surprising origin. The company NVision originally focused on developing a technology to improve the capabilities of magnetic resonance imaging in monitoring metabolic processes in the human body.
Researchers have been working with a method that allows for a significant amplification of the magnetic signal of certain molecules, such as specially prepared sugars. These substances can help in imaging the metabolic activity of tumor cells.
The scientists then used their experience in controlling electron spins to explore new possibilities for quantum computing.
The result is a technology that combines knowledge from medical research, organic chemistry, physics, and artificial intelligence.
The first prototypes of chips could be created this year
At the same time, NVision announced a collaboration with the American manufacturer of photonic chips, HyperLight.
Both companies want to integrate the newly developed molecular qubits directly into existing chip structures and verify their practical applications.
The first prototypes of integrated chips are expected in the last quarter of 2026.
However, the company's long-term ambition is not only to supply new materials to electronics manufacturers. NVision wants to develop complete quantum computers, including the processors and systems needed to correct errors in quantum computations.
There is still a long way to go before a true quantum computer
Despite the promising results, this is not yet a complete quantum processor. Previous experiments have demonstrated the functionality of individual molecular qubits in laboratory conditions, at a temperature of approximately minus 269 degrees Celsius.
Scientists now need to verify whether the molecules will retain the necessary properties even after being incorporated into actual chips, and whether it will be possible to reliably connect a larger number of qubits.
Only then will it be possible to assess whether the new manufacturing method will actually bring the expected economic benefits.
Nevertheless, the published research represents a significant step. It shows that quantum computers do not necessarily have to rely solely on complex manufacturing technologies developed specifically for them.
If it is possible to use existing industrial processes, this could significantly accelerate their development in the future and open the way to more accessible quantum systems.
