Research team expands quantum network with successful long-distance entanglement experiment
Posted by Genevieve Klien in categories: computing, particle physics, quantum physics
Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University, and DOE’s Energy Sciences Network (ESnet) are collaborating on an experiment that puts U.S. quantum networking research on the international map. Researchers have built a quantum network testbed that connects several buildings on the Brookhaven Lab campus using unique portable quantum entanglement sources and an existing DOE ESnet communications fiber network—a significant step in building a large-scale quantum network that can transmit information over long distances.
“In quantum mechanics, the physical properties of entangled particles remain associated, even when separated by vast distances. Thus, when measurements are performed on one side, it also affects the other,” said Kerstin Kleese van Dam, director of Brookhaven Lab’s Computational Science Initiative (CSI). “To date, this work has been successfully demonstrated with entangled photons separated by approximately 11 miles. This is one of the largest quantum entanglement distribution networks in the world, and the longest-distance entanglement experiment in the United States.”
This quantum networking testbed project includes staff from CSI and Brookhaven’s Instrumentation Division and Physics Department, as well as faculty and students from Stony Brook University. The project also is part of the Northeast Quantum Systems Center. One distinct aspect of the team’s work that sets it apart from other quantum networks being run in China and Europe—both long-committed to quantum information science pursuits—is that the entanglement sources are portable and can be easily mounted in standard data center computer server racks that are connected to regular fiber distribution panels.

This Neural Implant Accesses Your Brain Through the Jugular Vein
Posted by Quinn Sena in categories: biotech/medical, computing, neuroscience, security
A permanent neural implant that reads brain activity and churns out text could prove to be a valuable medical tool, but it also could provide doctors with an unprecedented 24/7 stream of neural data.
Oxley recognizes that an endless feed of brain activity could be invaluable to medical researchers, but he doesn’t have plans to tap into that yet.
“[The Stentrode is] going to show us information that we hadn’t had before. Whether that helps us understand other things is not what we’re trying to do here,” he said, clarifying that Synchron’s primary goal is to get the new brain-computer interface working so that it can help paralyzed patients. “This is a novel data set, but this raises questions around privacy and security. That’s the patient’s data, and we can’t be mining that.”

This is the first computer-generated genome
Posted by Genevieve Klien in categories: biotech/medical, computing
Scientists report the world’s first fully computer-generated genome of a living organism.
To do so, they used a new method that greatly simplifies the production of large DNA molecules containing many hundreds of genes. They report their work in PNAS.
All the genome sequences of organisms known throughout the world are stored in a database belonging to the National Center for Biotechnology Information in the United States. Now, the database has an additional entry: Caulobacter ethensis-2.0.

Quantum Computers Could Go Mainstream Sooner than We Think
Posted by Genevieve Klien in categories: computing, quantum physics
Computers were once considered high-end technology, only accessible to scientists and trained professionals. But there was a seismic shift in the history of computing during the second half of the 1970s. It wasn’t just that machines became much smaller and more powerful—though, of course, they did. It was the shift in who would use computers and where: they became available to everyone to use in their own home.
Today, quantum computing is in its infancy. Quantum computation incorporates some of the most mind-bending concepts from 20th-century physics. In the US, Google, IBM, and NASA are experimenting and building the first quantum computers. China is also investing heavily in quantum technology.
As the author of Quantum Computing for Everyone, published in March, I believe that there will be an analogous shift toward quantum computing, where enthusiasts will be able to play with quantum computers from their homes. This shift will occur much sooner than most people realize.

Russia Says “Super Soldiers” Can Crash Computers With Telepathy
Posted by Quinn Sena in categories: computing, military, neuroscience
According to a report in the official magazine of its Defense Ministry, Russian “supersoldiers” are able to use “parapsychology” techniques to crash enemy computers, access the minds of foreign soldiers, and read documents inside locked safes — abilities they gained, according to the article, from telepathic dolphins they can now communicate with.
The report is almost certainly nonsense. But it does raise questions about the ambitions — and perhaps dysfunctions — of Russia’s military.

Scientists Found an Edible Mushroom That Eats Plastic, and It Could Clean Our Landfills
Posted by Quinn Sena in categories: biotech/medical, computing, food, transportation
Whether we like it or not, our society has become completely reliant on plastic. From food preservation to water transportation, computer technology to healthcare and medicine, plastic can be found in nearly every facet of the human experience.
But as we well know, plastic is a double-edged sword, with massive amounts of plastic waste not only piling up in landfills, but floating in the most remote depths of our oceans and water supplies. And despite our knowledge of plastic’s harmful effects on the environment, we’ve become so reliant on plastic that there seems to be no end in sight. In fact, plastic production is growing on a yearly basis–and posing a potentially mortal threat to us all.
