Scientists have developed a new method to track how quickly information disappears in quantum computers. This breakthrough could lead to more stable and reliable machines.

Quantum computers are still far from being dependable due to their biggest weakness - instability. Information processed by these computers can break down quickly, making it difficult to improve performance and reliability. Researchers have been working to solve this problem, including a team in Norway led by Professor Jeroen Danon at the Norwegian University of Science and Technology (NTNU) Department of Physics.

The challenge has been figuring out exactly how fast information disappears. Without knowing this, scientists couldn't improve the performance and reliability of quantum systems. The time it takes for information to disappear varies randomly over time, making it difficult to measure.

Danon and his colleagues have developed a new measurement method that enables them to track the time it takes to lose information with unparalleled speed and accuracy - more than 100 times faster than before. This allows researchers to track how information fades as it happens and reveals subtle, rapid changes that were previously impossible to detect.

This breakthrough could reshape how scientists test and fine-tune quantum processors. By better understanding the tiny processes that limit performance, researchers can work toward more stable and reliable machines. That progress brings quantum computing one step closer to reaching its full potential.
