Swiss scientists have succeeded in creating a perfect sequence of random numbers
Researchers from the Swiss Federal Institute of Technology in Zurich have announced that they have achieved a significant result that was considered impossible for many years. This was reported by Zamin.uz.
Scientists have succeeded in creating a sequence of perfectly random numbers that can be mathematically proven. While this may seem like a simple task at first glance, in practice, even random numbers obtained using the highest quality dice, coins, and modern computer programs possess a certain degree of uncertainty or repeating patterns.
A group led by physicists Renato Renner and Andreas Vallraff proposed a method of randomness amplification to solve this problem. During the experiment, two superconducting quantum bits, cooled to nearly absolute zero and connected by a special thirty-meter communication line, were used.
These quantum bits are in a state of mutual entanglement, where the measurement result of one object is immediately linked to the second. This state ensures that the system is free from external influences.
The core of the research consists of an improved method of the Bell test. This experiment allows for the verification that the results obtained are determined not by hidden factors, but by the actual quantum nature of the system.
Although the researchers intentionally used imperfect tools to choose the measurement method, a special calculation algorithm processed the obtained data and extracted mathematically ideal randomness from them. The scientists noted that it is now possible not only to generate random numbers but also to fully confirm their randomness from a physical point of view.
This is not merely a statistical approximation, but a result that will absolutely not lose its randomness property regardless of what analysis methods or powerful computing machines are developed in the future. The practical significance of this discovery is incomparable.
Modern data encryption systems, digital signatures, cryptocurrencies, and blockchain technologies rely precisely on the quality of random numbers. If there is even a hint of predictability in the source of randomness, it puts the entire security system at risk.
The authors compare their development to atomic clocks. If atomic clocks are the world standard for time measurement, quantum generators will serve as the standard for reliability and randomness for the future digital infrastructure.
