Benchmarking highly entangled states on a 60-atom analogue quantum simulator. (https://pubmed.ncbi.nlm.nih.gov/38509372/)

These scientists wanted to see how well a special type of computer called a quantum computer can create something called entanglement, which is a very important property in quantum physics. They found that when quantum systems become very complex, regular computers have a hard time keeping up with them.

To test this, the scientists used a simulated quantum system made up of 60 atoms. They created a way to measure how well this simulated quantum system could create entanglement compared to a regular computer. They also developed a way to estimate the amount of entanglement in their experiment.

The scientists found that their simulated quantum system was just as good as the most advanced digital quantum computers at creating entanglement. They also compared the accuracy of different types of regular computer algorithms and found that only their new algorithm could match the performance of the quantum system.

Overall, this study showed that quantum computers are very powerful when it comes to creating entanglement, and regular computers struggle to keep up with them in this aspect.
