With the rise in technology, the need of ultrafast quantum computer has also increased that can work on huge numbers and calculations at the same time. Quantum technology has long been a scientific dream, but now it is a step closer to becoming a reality after a team of scientists has figured out a way for a standard silicon chip to tackle quantum entanglement. Entanglement — a phenomenon in which multiple particles are connected to each other and act in uniform no matter their distance apart — is the key ingredient that promises to make ultrafast quantum computers and secure communications (encryption) far more powerful than conventional computing devices. The new research, detailed in The Optical Society’s (OSA’s) new high-impact journal Optica, describes how a multinational collaboration of boffins, for the first time, have created a new Micro-Ring Resonator that can generate a continuous supply of entangled photons; photons are essentially the particles that make up light. Full Article
