Scientists Managed to Transmit as Much Data as the Entire Internet’s Bandwidth

Posted by in categories: computing, internet

The world wide web is not enough, because scientists have managed to transmit data at a staggering 1.84 petabits per second — nearly twice the amount of global internet traffic in the same interval.

That blows the previous record for data transmission using a single light source and optical chip of one petabit per second out the water. And to put that ridiculous amount into perspective, a petabit is equal to one million gigabits. A single gigabit, or 1,000 megabits, is about the fastest download speed money can buy for most households.

To achieve the astonishing feat, researchers from the Technical University of Denmark (DTU) and Chalmers University of Technology used a custom optical chip that can make use of a single infrared light by splitting it into hundreds of different frequencies that are evenly spaced apart. Collectively, they’re known as a frequency comb. Each frequency on the comb can discretely hold data by modulating the wave properties of light, allowing scientists to transmit far more bits than conventional methods.

Researchers create first quasiparticle Bose-Einstein condensate

Posted by in categories: computing, particle physics, quantum physics

Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle properties like charge and spin. For decades, it was unknown whether they could undergo Bose-Einstein condensation in the same way as real particles, and it now appears that they can. The finding is set to have a significant impact on the development of quantum technologies including quantum computing.

A paper describing the process of creation of the substance, achieved at temperatures a hair’s breadth from absolute zero, was published in the journal Nature Communications.

Bose-Einstein condensates are sometimes described as the fifth state of matter, alongside solids, liquids, gases and plasmas. Theoretically predicted in the early 20th century, Bose-Einstein condensates, or BECs, were only created in a lab as recently as 1995. They are also perhaps the oddest state of matter, with a great deal about them remaining unknown to science.

Scientists Fed the Fibonacci Sequence Into a Quantum Computer and Something Strange Happened

Creating fast, reliable 3D scans of flora and fauna

Posted by in categories: biotech/medical, computing

Reporting in Research Ideas and Outcomes, a Kyushu University researcher has developed a new technique for scanning various plants and animals and reconstructing them into highly detailed 3D models. To date, over 1,400 models have been made available online for public use.

Open any textbook or nature magazine and you will find stunning high-resolution pictures of the diverse flora and fauna that encompass our world. From the botanical illustrations in Dioscorides’ De materia medica (50−70 CE) to Robert Hooke’s sketches of the microscopic world in Micrographia (1665), scientists and artists alike have worked meticulously to draw the true majesty of nature.

A single chip has managed to transfer the entire internet’s traffic in a single second

Posted by in categories: computing, internet

A single chip has managed to transfer over a petabit-per-second according to research by a team of scientists from universities in Denmark, Sweden, and Japan. That’s over one million gigabits of data per second over a fibre optic cable, or basically the entire internet’s worth of traffic.

The researchers—A. A. Jørgensen, D. Kong, L. K. Oxenløwe—and their team successfully showed a data transmission of 1.84 petabits over a 7.9km fibre cable using just a single chip. That’s not quite as fast as some other alternatives with larger, bulkier systems, which have reached up to 10.66 petabits, but the key here is scale: the proposed system is very compact.

Decoder uses fMRI brain scans to reconstruct human thoughts

Posted by in categories: biotech/medical, computing, information science, neuroscience

Researchers at the University of Texas at Austin have developed a decoder that uses information from fMRI scans to reconstruct human thoughts. Jerry Tang, Amanda LeBel, Shailee Jain and Alexander Huth have published a paper describing their work on the preprint server bioRxiv.

Prior efforts to create technology that can monitor and decode them to reconstruct a person’s thoughts have all consisted of probes placed in the brains of willing patients. And while such technology has proven useful for research efforts, it is not practical for use in other applications such as helping people who have lost the ability to speak. In this new effort, the researchers have expanded on work from prior studies by applying findings about reading and interpreting brain waves to data obtained from fMRI scans.

Recognizing that attempting to reconstruct brainwaves into individual words using fMRI was impractical, the researchers designed a decoding device that sought to gain an overall understanding of what was going on in the mind rather than a word-for-word decoding. The decoder they built was a that accepted fMRI data and returned paragraphs describing general thoughts. To train their algorithm, the researchers asked two men and one woman to lie in an fMRI machine while they listened to podcasts and recordings of people telling stories.

Dynamical topological phase realized in a trapped-ion quantum simulator

Posted by in categories: computing, quantum physics

Basically the fibonacci sequence stabilized the quantum computers internal processes better essentially. This may fall into the theory of everything that supersymmetry and the fibonacci sequence can get us closer to a theory of everything even in quantum computers.


A dynamical topological phase with edge qubits that are dynamically protected from control errors, cross-talk and stray fields, is demonstrated in a quasiperiodically driven array of ten 171Yb+ hyperfine qubits in a model trapped-ion quantum processor.

A Single Laser Transmitted a Second’s Worth of Internet Traffic in Record Time

Posted by in categories: computing, internet

Scientists continue to blow through data transmission records, with the fastest transmission of information between a laser and a single optical chip system now set at 1.8 petabits per second. That’s well in excess of the amount of traffic passing across the entire internet each second.

Here’s another comparison: the average broadband download speed in the US is 167 megabits per second. You need 1,000 megabits to get to a gigabit, and then 1 million gigabits to get up to 1 petabit.

No matter how you present it, 1.8 petabits is a serious amount of data to transmit in a second.
