DIY gravitational waves with ‘BlackHoles@Home’
Posted by Quinn Sena in categories: computing, cosmology, physics
Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help.
West Virginia University assistant professor Zachariah Etienne is leading what will soon become a global volunteer computing effort. The public will be invited to lend their own computers to help the scientific community unlock the secrets contained in gravitational waves observed when black holes smash together.
LIGO’s first detection of gravitational waves from colliding black holes in 2015 opened a new window on the universe, enabling scientists to observe cosmic events spanning billions of years and to better understand the makeup of the Universe. For many scientists, the discovery also fueled expansion of efforts to more thoroughly test the theories that help explain how the universe works—with a particular focus on inferring as much information as possible about the black holes prior to their collision.

The Army’s Next Infantry Guns Will Have Computerized Fire Control for Unreal Accuracy
Posted by Derick Lee in category: computing
The U.S. Army’s next assault rifle and machine gun will have built-in computers to give soldiers unparalleled firing accuracy. The so-called Next Generation Squad Weapons will feature a digital fire control system borrowing many features from today’s main battle tanks, allowing shooters to engage targets faster and with greater precision than their opponents can muster.
Next generation infantry weapons will incorporate computer technology previously only available on tanks.

Team makes artificial atoms that work at room temp
Posted by Quinn Sena in categories: computing, particle physics, quantum physics
Ultra-secure online communications, completely indecipherable if intercepted, is one step closer with the help of a recently published discovery by University of Oregon physicist Ben Alemán.
Alemán, a member of the UO’s Center for Optical, Molecular, and Quantum Science, has made artificial atoms that work in ambient conditions. The research, published in the journal Nano Letters, could be a big step in efforts to develop secure quantum communication networks and all-optical quantum computing.
“The big breakthrough is that we’ve discovered a simple, scalable way to nanofabricate artificial atoms onto a microchip, and that the artificial atoms work in air and at room temperature,” said Alemán, also a member of the UO’s Materials Science Institute.

Scientists Say New Quantum Material Could “‘Download’ Your Brain”
Posted by Quinn Sena in categories: computing, health, neuroscience, quantum physics
Scientists say they’ve developed a new “quantum material” that could one day transfer information directly from human brains to a computer.
The research is in early stages, but it invokes ideas like uploading brains to the cloud or hooking people up to a computer to track deep health metrics — concepts that until now existed solely in science fiction.

New algorithm optimizes quantum computing problem-solving
Posted by Quinn Sena in categories: business, computing, information science, particle physics, quantum physics
Tohoku University researchers have developed an algorithm that enhances the ability of a Canadian-designed quantum computer to more efficiently find the best solution for complicated problems, according to a study published in the journal Scientific Reports.
Quantum computing takes advantage of the ability of subatomic particles to exist in more than one state at the same time. It is expected to take modern-day computing to the next level by enabling the processing of more information in less time.
The D-Wave quantum annealer, developed by a Canadian company that claims it sells the world’s first commercially available quantum computers, employs the concepts of quantum physics to solve ‘combinatorial optimization problems.’ A typical example of this sort of problem asks the question: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city and returns to the original city?” Businesses and industries face a large range of similarly complex problems in which they want to find the optimal solution among many possible ones using the least amount of resources.

Scientists build a machine to generate quantum superposition of possible futures
Posted by Genevieve Klien in categories: computing, information science, particle physics, quantum physics
In the 2018 movie Avengers: Infinity War, a scene featured Dr. Strange looking into 14 million possible futures to search for a single timeline in which the heroes would be victorious. Perhaps he would have had an easier time with help from a quantum computer. A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) and Griffith University in Australia have constructed a prototype quantum device that can generate all possible futures in a simultaneous quantum superposition.
“When we think about the future, we are confronted by a vast array of possibilities,” explains Assistant Professor Mile Gu of NTU Singapore, who led development of the quantum algorithm that underpins the prototype “These possibilities grow exponentially as we go deeper into the future. For instance, even if we have only two possibilities to choose from each minute, in less than half an hour there are 14 million possible futures. In less than a day, the number exceeds the number of atoms in the universe.” What he and his research group realised, however, was that a quantum computer can examine all possible futures by placing them in a quantum superposition – similar to Schrödinger’s famous cat, which is simultaneously alive and dead.
To realise this scheme, they joined forces with the experimental group led by Professor Geoff Pryde at Griffith University. Together, the team implemented a specially devised photonic quantum information processor in which the potential future outcomes of a decision process are represented by the locations of photons – quantum particles of light. They then demonstrated that the state of the quantum device was a superposition of multiple potential futures, weighted by their probability of occurrence.
