Bill Gates and MIT unveil quantum dot technology to mark children’s skin so they can be scanned for vaccine compliance and anything else to be determined later. The MIT researchers have been funded by the Bill and Melinda Gates Foundation and the National Cancer Institute. This new technology uses nano-crystal dyes called quantum microdots. These patterns of dye contain data that can for now mark that a vaccine has been received into the person’s body.This pattern of dye is embedded under the skin as a vaccine is injected into the human recipient. Therefore, these dots can be injected into the...

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within graphene, a single layer of tightly packed carbon atoms. This tiered "wedding cake," which appears in images that show the energy level structure of the electrons, experimentally confirms how electrons interact in a tightly confined space according to long-untested rules of quantum mechanics. The findings could also have practical applications in quantum computing. Graphene is a highly promising material for new electronic devices because of...
