The systems are correlated, even when they are separated by a large distance. The significant potential for applications in encryption, communications and quantum computing spurs research. The difficulty is that when the systems interact with their surroundings, they almost immediately become disentangled.<\/p>\n<p>In the latest study by the Laboratory for Coherent Manipulation of Atoms and Light (LMCAL) at the University of S\u00e3o Paulo\u2019s Physics Institute (IF-USP) in Brazil, the researchers succeeded in developing a light source that produced two entangled light beams. Their work is published in Physical Review Letters.<\/p>\n<p>\u201cThis light source was an optical parametric oscillator, or OPO, which is typically made up of a non-linear optical response crystal between two mirrors forming an optical cavity. When a bright green beam shines on the apparatus, the crystal-mirror dynamics produces two light beams with <a href=\"https:\/\/phys.org\/tags\/quantum+correlations\/\" rel=\"tag\" class=\"\">quantum correlations<\/a>,\u201d said physicist Hans Marin Florez, last author of the article.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists are increasingly studying quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others.
