graphene could deliver Internet one hundred times faster

 

 

The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times, according to new research by scientists in our Department of Physics.
 

In a paper published in Physical Review Letters, researchers from the Centre for Graphene Science at the Universities of Bath and Exeter have demonstrated for the first time incredibly short optical response rates using graphene, which could pave the way for a revolution in telecommunications.

NearBytes short-range communication technology transmits data as sound

NFC has been hailed as the next big thing for a few years now, but adoption has been a lot slower than anticipated with people required to update their phones to NFC-capable models to take advantage of the technology. Brazilian startup Kinetics has developed a new communication technology called NearBytes that allows data transfer between older smartphones, including all existing Android and iOS smartphones, by using sound

Pitched as an alternative to Near Field Communication (NFC), NearBytes sees the transmitting device encrypt the data and send it as a series of chirps that sound similar to a cricket. The receiving device then captures these sounds and decodes the data. As it relies only on the devices' microphone and speaker, NearBytes doesn't require any special hardware. The only requirement is that the devices be within 10 cm (3.93 inches) of each other

Samsung reveals entry-level 1TB 'SSDs for everyone'

http://www.dvice.com...b-ssds-everyone

Just a handful of years, solid state drives (SSD) were considered "nice to have" storage. While everyone from professionals to gamers to casual users now see how beneficial faster SSD transfers are, there are still a few reasons why they're not "must haves." Price and capacity still continue to deter users from choosing SSDs over traditional platter-based hard drives. The tables are finally starting to turn, though, at least for capacity.

At its SSD Global Summit, Samsung announced its new SSD 840 EVO, the successor to last year's 840 Series SSDs, now with capacities from 120GB up to 1TB. Yes, the era of 750GB SSD and 1TB SSD is finally upon us.

Using a 10-nanometer class manufacturing process, the new 250GB 840 EVO SSDs are two times faster than the previous generation — with write speeds of 520MB/s. A 120GB 840 EVO SSD model isn't far behind with write speeds of 410MB/s — three times faster than the previous 120GB 840 SSD, according to Samsung.

China smartphone owners swell number of internet users

China now has 591 million internet users, according to the latest official figures from the country.

The China Internet Network Information Centre added that 464 million citizens accessed the net via smartphones or other wireless devices.

The headline figure marks a 10% rise on last year and indicates 44% of the country's population uses the web and other net services.

Someone just mention the graphene few posts before - I've just found some more info about it over the web - check it out here: http://www.nano-man....nes.html]Jagged graphene edges can slice into cell membranes[/url] and here: Just an atom thick and 200 times stronger than steel and a near perfect conductor - it seems that graphene is the next future material which will be as common as a steel is on these days

D-Wave 2 Labeled World's First Quantum Computer; Utilizes 512 Qubits

 

http://wccftech.com/...super-computer/

Imagine the history of classical computers throughout a full century; now compress this advancement into 20-30 years. This may be how the quantum computing revolution goes. From UNIVAC to Watson in a generation.

What does it mean "faster than universe"?

 

Perhaps under this scenario, one would think the Universe as a computer or a numerical simulation, so a quantum computer with sufficient qubits can process certain types of problems faster than the Universe can within a certain interval of time or the entire age of the Universe depending on how you look at it.

 

 

 

EDIT: I found this website that discusses Rose's Law. The answer about "faster than the Universe" question is in the sentence I underlined in bold below.

 

http://www.flickr.co...son/8054771535/

 

So, how do we read the graph above? Like Moore’s Law, a straight line describes an exponential. But unlike Moore’s Law, the computational power of the quantum computer should grow exponentially with the number of entangled qubits as well. It’s like Moore’s Law compounded. (D-Wave just put together an animated visual of each processor generation in this video, bringing us to the present day.)

And now, it gets mind bending. If we suspend disbelief for a moment, and use D-Wave’s early data on processing power scaling (more on that below), then the very near future should be the watershed moment, where quantum computers surpass conventional computers and never look back. Moore’s Law cannot catch up. A year later, it outperforms all computers on Earth combined. Double qubits again the following year, and it outperforms the universe. What the???? you may ask... Meaning, it could solve certain problems that could not be solved by any non-quantum computer, even if the entire mass and energy of the universe was at its disposal and molded into the best possible computer.

probably a simulation of the big bang or the universe itself. That's about all I can imagine

3D CMOSS Memristor Circuits

 

 

There is work towards creating 3D CMOs memristor circuits

Maximum Number of Layers
• Each layer has N^2 cells.
• There are r^2– 1 cross points per cell.
• That gives us a total of N^2 * (r^2 – 1) cross points per layer.
• The double decoding scheme allows us to address up to N^4 locations
• Which means that we can (potentially) have up to N^2 /(r^2 – 1) crossbar layers.

If Successful, 3D Hybrids Can Achieve…..
• Unprecedente dmemory density
– Footprint of a nano‐device is 4F nano 2/K, for K vertically integrated crossbar layers
– Potentially up to 10^14 bits on a single 1‐cm^2 chip
• Enormous memory bandwidth
– Potentially up to 10^18 bits/second/cm2
• At manageable power dissipation
• With abundant redundancy for yield/reliability

What difference does it make?

I think it just means if the entire universe was a classical computer, that it would be faster than that. Certainly mind blowing, but it makes sense I think

I've read somewhere that the computational power of a quantum computer doubles for each qbit added. Is that true?
