Quantum systems are inherently fragile as any interactions with the outside world can change their state. That makes creating things like quantum memories rather challenging, since it can be hard to know if it actually preserves the information you put into it. To get around this, researchers have been looking into ways...
Entanglement is one of the most intriguing features of quantum mechanics. It describes non-local correlations between quantum objects, and is at the heart of quantum information sciences. Entanglement is now being studied in diverse fields ranging from condensed matter to quantum gravity. However, measuring entanglement remains a challenge. This is especially so in systems of interacting delocalized particles, for which a direct experimental measurement...
A property called entanglement entropy helps to describe the quantum states of interacting particles, and it has at last been measured. The findings open the door to a deeper understanding of quantum systems. See Article p.77
