Researchers have used quantum superposition to help qubits violate a fundamental quantum limit, allowing them to maintain information five times longer. This breakthrough involves a three-qubit system that demonstrates extreme correlations over time. The finding could enhance quantum computing and metrology applications.

Researchers propose using tiny 'Ferris wheels' made from laser light to confine and rotate extremely cold atoms or molecules, potentially testing Einstein's theory of relativity on quantum scales. This method aims to observe time dilation effects in ultracold particles, where quantum properties can be precisely manipulated. The approach builds on earlier work and could reveal unexpected effects in an unexplored setting.
