Stable quantum-correlated many-body states through engineered dissipation. (https://pubmed.ncbi.nlm.nih.gov/38513021/)
These scientists used a special kind of system made up of tiny particles called qubits to study how things behave at a very small scale. They wanted to see if they could make these particles work together in a way that could help us understand things like high-temperature superconductivity or quantum magnetism.
To do this, the scientists used up to 49 superconducting qubits and connected them to other qubits that could help control how the system behaves. They found that by doing this, they could create states where the qubits had very low energy, kind of like when you're very calm and relaxed.
When they looked at the qubits in one dimension (like a straight line), they saw that they were connected in a special way that allowed them to share information over long distances. They also found that the qubits were in a very stable state at a critical point, kind of like when something is perfectly balanced.
Then, they looked at the qubits in two dimensions (like on a flat surface) and saw that they could share information even if they weren't right next to each other. This was like having a secret code that could be passed along in a special way.
Finally, the scientists connected the system to other qubits that acted like different types of reservoirs, which helped them understand how things move around in the system. By doing all of this, they showed that they could use this method to create special states where the qubits were all connected and working together, even if there was some noise or interference.
Overall, this study showed that by using these special systems and methods, scientists can make tiny particles work together in a very organized and controlled way, which can help us learn more about how things work at a very small scale.
