Plans for an ultra-advanced quantum Internet received a major boost with an early May reveal by MIT Technology Review that Los Alamos National Labs has been working on the technology for more than two years.
Quantum computing makes use of quantum elements and their peculiar properties to give computers new abilities, preferably abilities that will lead to a more efficient and safer digital age.
The Los Alamos project, which has been going on for two-and-a-half years, has focused on quantum encryption that automatically makes messages secure, showing any type of tampering by examining telltale changes on the quantum level. Previous efforts in quantum security have only affected “point-to-point connections” across a single line, so the safety measures could not be applied to any routed data — making quantum Internet computing impossible.
The Los Alamos project tackled the issue by creating a central hub that sends and receives quantum messages through multiple lines, as needed. Messages sent to the hub use quantum encryption that senses any type of snooping, while messages in the hub are decrypted and then encrypted once again when data is sent out. Multiple nodes located along the lines help transmit quantum messages to the hub, making the technology more efficient and flexible.
For now, the Los Alamos project is still in development, with continued work to make the devices smaller and more manageable. Similar projects around the world are also tackling quantum routers and other systems, all somewhat in competition with each other. This competition may one day lead to a new approach to the Internet, where communications are entirely secure and safe from any current type of data theft.
The move toward quantum encryption promises plenty of new business for tech industries. The Los Alamos version, for example, can be used as a “security retrofit” for fiber optic lines. This requires both a fiber optic installation — an upgrade that much of the American infrastructure lacks — and the application of new technology that requires technicians with a set of new, advanced skills. While the University of Tokyo offers multiple courses on quantum nanodevices, quantum semiconductors, and integrated quantum electronics, corporations in Canada are offering major investments in quantum electronics startup businesses.
The result will be all-new fields in tech industries, universities and investment organizations, all inspired by quantum potential. First in line will be quantum Internet technology that makes data safer than ever, ushering in major changes for IT security departments across the world.
