Theorists at the Max Planck Institute of Quantum Optics have made a significant stride in the field of quantum computing. Their research addresses a long-standing question: can quantum computers really outperform classical computers in solving complex problems, despite the presence of errors?
In a new study focusing on analogue quantum simulators – specialised quantum devices used to mimic physical systems – the researchers could show precisely that: quantum simulators can remain stable and provide accurate results, even when subjected to errors.
This finding is groundbreaking as it suggests that practical quantum advantage, where quantum computers outscore classical ones, may be within reach sooner than previously thought.
The work was recently published in Nature Communications.
