How do we know that a quantum system really behaves quantum mechanically?

Researchers at the Department of Physics, Stockholm University and colleagues from other universities have developed and implemented a test that can reveal just that. Using entangled photons and a form of so-called non-locality inequalities (CHSH and CGLMP), they have shown that some experimental outcomes can only be explained by higher dimensional quantum systems. The higher the dimension of a quantum system, the more information it can carry - and the more powerful some quantum technologies can become. The result is an important step towards safe and reliable quantum technologies. It means we can build quantum devices where you don't have to rely blindly on the manufacturer or the technology, but where physics itself guarantees that quantum information is actually used.
