New Scientist reporter Leah Crane writes that a set of mirrors at LIGO have been cooled to near absolute zero, the largest objects to be brought to this frigid temperature. “The goal of this work is to help explain why we don’t generally see macroscopic objects in quantum states, which some physicists have suggested may be due to the effects of gravity,” writes Crane.
MIT researchers have developed a new atomic clock that can keep time more precisely thanks to the use of entangled atoms, reports Leila Stein for Popular Mechanics. “If all atomic clocks worked the way this one does then their timing, over the entire age of the universe, would be less than 100 milliseconds off,” Stein writes.
Writing for Scientific American, Prof. Carlo Ratti explores the “transformative” potential of quantum sensors. Ratti writes that quantum sensors could enable autonomous vehicles to “‘see’ around corners, underwater navigation systems, early-warning systems for volcanic activity and earthquakes, and portable scanners that monitor a person's brain activity during daily life.”
Gizmodo reporter Ryan Mandelbaum writes that by studying ancient quasars, MIT scientists have uncovered evidence supporting quantum entanglement, the concept that two particles can become linked despite their distance in space and time. “We’ve outsourced randomness to the furthest quarters of the universe, tens of billions of light years away,” says Prof. David Kaiser.
Writing for Motherboard, Daniel Oberhaus highlights how MIT researchers have used light emitted by quasars billions of years ago to confirm the existence of quantum entanglement. Oberhaus explains that the findings suggest entanglement occurs “because if it didn’t exist the universe would somehow have to have ‘known’ 7.8 billion years ago that these MIT scientists would perform these experiments in 2018.”
MIT researchers have used starlight to test Einstein’s “spooky action” theory and have presented a strong demonstration of quantum entanglement, reports Calla Cofield for CBS News. Cofield explains that the researchers “measured about 100,000 pairs of entangled photons…and their results suggested that the particles were truly entangled.”
The Atlantic’s Natalie Wolchover writes that MIT physicists have presented a demonstration of quantum entanglement, addressing a loophole in quantum theory. Prof. Andrew Friedman says his team will continue testing the loophole, explaining, “either we close the loophole more…or we see something that could point toward new physics.”
Prof. Alan Guth speaks with Christina Couch of Science Friday about his career and the cosmos. Of what inspired him to pursue a career in science, Guth recalls conducting experiments with a friend and being “very excited about the idea that we can really calculate things, and they actually do reflect the way the real world works.”
MIT researchers have engineered viruses that take advantage of quantum physics, mimicking the process of photosynthesis, to enhance energy transfer, reports Alexandra Ossola for Popular Science. The work could result in “solar panels that transmit energy with unprecedented efficiency,” writes Ossola.
MIT physicists have cooled molecules to just above absolute zero, reports Macrina Cooper-White for The Huffington Post. “The team hopes to cool molecules to an even lower temperature, study the interactions between them, and learn more about the limits on their lifetime,” Cooper-White explains.
Jesse Emspak of Live Science writes that MIT researchers have successfully cooled molecules to just above absolute zero. The researchers found that when the molecules were cooled to 500 nanokelvins they “were quite stable, and tended not to react with other molecules around them.”
In a piece for PBS, Jennifer Ouellette writes about Professor John Bush’s work with quantum mechanics, in particular his replication of a quantum corral. “Time will tell whether the quantum-like behavior of the walking [droplets] is mere coincidence,” says Bush.
Dan Vergano of National Geographic profiles Professor Alan Guth’s career in physics. "What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that," Guth explains.
Bruce Dorminey writes for Forbes about how scientists are looking to close a quantum physics loophole. “We wanted to come up with a potential test that could close one of the last major remaining quantum physics loopholes that could still allow entangled particle experiments to be interpreted according to classical physics,” explains MIT postdoc Andrew Friedman.
Charles Q. Choi writes about Professor David Kaiser’s research into the last major loophole in quantum physics. “Kaiser and his colleagues have proposed looking for answers from the most remote corners of the known cosmos,” reports Choi.
