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.
On Jan. 23, Broadband World News hosts a Calix-sponsored webinar that explores several ways CSPs can enhance customer experience and find new business opportunities to avoid devolving into a speed race where nobody wins, not even the customer.
As the pool of savvy, fiber-rich operators across the US rural and regional landscape wanes, the financial community will grow even more interested in acquiring or investing in them, a CoBank report says.
It wasn't long ago that TV was ranked by subscribers as the most important service in the bundle provided by their communications service provider (CSP). Recent research indicates that for nearly three quarters of subscribers, broadband is now the most important service. Broadcast TV is the most important service to only 15% of North American consumers, replaced by OTT video streaming platforms like Netflix, Amazon Prime and Disney+. In addition, many different competitors are moving aggressively to stake a claim in consumers' homes.
In 2020, CSPs need to fight back by transforming their business models, which are becoming more reliant on a single source of revenue: fixed broadband services.
This webinar will focus on helping CSPs transform their business models by placing a firm focus on delivering a sensational subscriber experience and by offering compelling new services that generate value for subscribers. These actions will reinforce the CSP's strategic position in the home network and position themselves for growth in the next decade.
Key topics include:
Being the first to market with WiFi 6 technology, in response to consumer purchases of new devices over the holidays;
Having the insights needed to proactively resolve issues, often before your subscribers even know that there are issues;
Providing help desk agents with the visibility they need to resolve common subscriber issues more quickly;
Delivering a mobile app, in response to consumer demands for the ability to do some things themselves, rather than having to call technical support; and
Addressing consumer concerns around device security, privacy and control with enhanced security and parental controls.
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.
