(PhysOrg.com) -- Today, fiber optics technology transports information in the form of classical data to homes and businesses. But researchers are currently working on ways to combine quantum data with the classical data in fiber optics networks in order to increase security. In a new study, scientists have shown how quantum and classical data can be interlaced in a real-world fiber optics network, taking a step toward distributing quantum information to the home, and with it a quantum internet.

Nuclear magnetic resonance (NMR) is a powerful tool for chemical analysis and, in the form of magnetic resonance imaging (MRI), an indispensable technique for medical diagnosis. But its uses have been limited by the need for strong magnetic fields and big, expensive, superconducting magnets. Now Berkeley Lab scientists and their colleagues have demonstrated that they can do NMR in a zero magnetic field without using any magnets at all.
