Researchers have made an exotic quantum object called an Alice ring, which changes the properties of other quantum objects when they pass through it – or when they are simply viewed through it.
Researchers manipulated thousands of extremely cold atoms to make a ring-like defect that can change the properties of quantum objects that pass through it.
Scientists from Aalto University in Finland and Amherst College in Massachusetts created a bizarre quantum object known as an ‘Alice ring.’ An...
