A new form of artificial diamond one day could be the foundation for a highly secure, quantum ultra-broadband, according to a recent Science magazine article.
The designer crystal can both store quantum information for a long time and clearly transmit data, something artificial diamonds could not do previously: They could do only one or the other, the July 6 article said. These diamonds could, therefore, eventually become a foundation of a "quantum Internet" that would empower users to send secured messages via connected quantum computers around the globe.
Due to a flaw in synthetic diamonds, they can act as quantum storage: In the "defect," a non-carbon atom and an empty space replace two neighboring carbon atoms and demonstrate spin, a quantum property that can be in an up, down or up and down state. The Science article details the processes involved.
"Each of those states reflects a bit of quantum data, or qubit, that may be 1, 0 or both at once. A diamond transmits qubits by encoding them in light particles, or photons, that travel through fiber-optic cables," the magazine article reports.
These qubit-carrying photons cannot travel far, today, however: Only about 100km through optical fiber, making them poor options for worldwide communications. But, just like traditional telecommunications and cable technologies that advance by meters or miles, this may well be the first step in using these artificial diamonds for a specialized Internet that melds fiber optic cables and quantum computing.
During prepared comments to a conservative group in Maine, Federal Communications Commission Chairman Ajit Pai outlined his concerns with several states' independent moves to reinstate the 2015 laws governing the Internet.
Under a partnership announced today, Deutsche Telekom and United Smart Cities will help metro leaders with smart-city projects, ultimately leading to integrated solutions and a shareable database equipped with analytics tools for deep dives.
The MSO has pivoted from being a traditional cable operator into a connectivity provider, said Comcast Chairman and CEO Brian Roberts during the Goldman Sachs Communacopia Conference in New York this week.
AT&T is closer to deploying AirGig, following successful trials, and now seeks vendor partners to work on technologies that it believes will bring broadband closer to rural customers across power lines.
Fast, reliable broadband is essential to how we live, work and play today – and the upcoming arrival of 5G will only further increase demand and reliance on fiber infrastructure. Already viewed by consumers as intolerable, delays, outages or the regular maintenance difficulties associated with operating a network will become further exacerbated when residential subscribers further rely on connected devices for day-to-day life. Just as providers deploy network automation tools to reduce operational issues, they must take similar care to manage consumer expectations when they roll out fiber or new services. This webinar features leaders who will discuss how to manage marketing and consumer expectations at every stage of the network lifecycle. Marketing professionals, c-level executives and policymakers interested in drumming up fiber envy should attend.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
