Physics A method that relies on hitting materials with neutrons can measure how much quantum entanglement hides within them, which could enable new kinds of quantum technology Facebook / Meta Twitter / X icon Linkedin Reddit Email The behaviour of two distinct particles can be linked by quantum entanglement Science Photo Library / Alamy We finally have a way to measure quantum entanglement of solids, which could lead to advances in both quantum technology and fundamental physics. When it comes to quantum entanglement – an inextricable link between quantum particles that keeps their behaviours correlated, even when they are extremely far apart – researchers have limited experimental tools. They can determine if two particles are entangled by using a procedure called the Bell test , for example, and purposely create entanglement between several objects within quantum computers . But finding out whether a piece of some material is full of entangled particles is more challenging.…
