Quantum physics fundamentally redefines our understanding of nature by describing the behaviour of matter and energy at the smallest scales. Unlike classical theories, quantum mechanics reveals that ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...

Key result A six-year-long research effort has seen researchers in Canada build a chip-scale device that can generate multiphoton entangled states. (Courtesy: Ultrafast Optical Processing Group) ...
