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.
In a flurry of activity throughout the week, Donald (DJ) LaVoy, Deputy Under Secretary for Rural Development at the US Department of Agriculture, and his team spent about $145.8 million in the non-urban or suburban areas of seven states.
Calix reported revenue of $120.19 million – up 4% – in Q4 2019, putting a bounce in the step of company president and CEO Carl Russo and a shine to Calix's ongoing transition from hardware vendor to a provider of platforms enabled by cloud, APIs and subscriber experience.
Looking to curtail e-waste and improve the bottom line, BT will require customers to return routers and set-top boxes, although subscribers will not have to pay a fee when they receive regular broadband equipment.
Deploying DOCSIS 3.1 across its entire footprint gave Rogers Communications the ability to offer speeds of up to 1 Gbit/s,
contributing to a broadband segement that generated about 60% of the Canadian operator's $3.05 billion (US) in Q4 cable earnings.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
