Experiment obtains entanglement of six light waves with a single laser

Publicado em 09 setembro 2018
Entanglement occurs when groups of particles or waves are created or interact in such a way that the quantum state of each particle or wave cannot be described independently of the others, however far apart they are. Experiments performed at the University of São Paulo’s Physics Institute (IF-USP) in Brazil have succeeded in entangling six light waves generated by a simple laser light source known as an optical parametric oscillator. Articles about these experiments have been published in [...]
