Topological quantum systems are physical systems exhibiting properties that depend on the overall connectivity of their underlying lattice, as opposed to local interactions and their microscopic structure. Predicting the evolution of these systems over time and their long-range quantum correlations is often challenging, as their behavior is not defined by magnetization or other parameters linked to local interactions. /news/2025-08-topological-properties-quantum-liquids-rydberg.html Quantum Â鶹ÒùÔºics Sun, 17 Aug 2025 08:00:02 EDT news674470369 The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and communication systems.

One of the important aspects of classical physics is that nothing, not even information, can travel faster than the speed of light. However, in the 1930s, scientists discovered that very small particles abide by some very different rules. One of the most mind-boggling behaviors exhibited by these particles is quantum entanglement—which Albert Einstein famously called "spooky action at a distance." /news/2025-08-scientists-quantum-entanglement-results-entangled.html Quantum Â鶹ÒùÔºics Mon, 04 Aug 2025 11:30:05 EDT news673525229 Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter!
