Scientists create quantum entanglement on a silicon chip



A team of scientists has figured out a way for a standard silicon chip to tackle quantum entanglement — a phenomenon in which multiple particles are connected to each other and act in uniform, regardless of how far apart they are. The scientists’ findings were detailed on Monday in a research paper published in Optica, a monthly journal by The Optical Society (OSA).

So far, harnessing the power of quantum entanglement onto silicon chips has proven to be a difficult task because of the large size of the devices used to emit entangled photons; photons are essentially the particles that make up light. Creating silicon chips — which are inexpensive and prevalent compared to specialized entanglement equipment — that can handle quantum entanglement is a big deal in that it can allow for more powerful computer chips and better encryption technology.
