Researchers at the University of the Witwatersrand have found ways to control the spin transport in networks of the smallest electrical conductor known to man. By chemically attaching nano-particles of the rare earth element, gadolinium, to carbon nanotubes, the researchers have found that the electrical conductivity in the nanotubes can be increased by incorporating the […]
Researchers Demonstrate Quantum Teleportation Of Patterns Of Light
Quantum communication over long distances is integral to information security and has been demonstrated in free space and fibre with two-dimensional states, recently over distances exceeding 1200 km between satellites. But using only two states reduces the information capacity of the photons, so the link is secure but slow. To make it secure and fast […]
