A team of researchers, including scientists from MIT, “simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole,” reports Dennis Overbye for The New York Times. The development is another “step in the effort to understand the relation between gravity, which shapes the universe, and quantum mechanics, which governs the subatomic realm of particles,” writes Overbye.
Prof. David Kaiser discussed the significance of Alain Aspect, John F. Clauser and Anton Zeilinger’s research conducting experiments concerning quantum entanglement, for which they were honored with the 2022 Nobel Prize in Physics. “Clauser got a lot of pushback from scientists who didn’t think this was even part of science,” said Kaiser. “He had to have a lot of stick-to-itiveness to publish his result.”
Popular Science reporter Rahul Rao writes that researchers from MIT and Harvard have whipped up quantum tornadoes, “the latest demonstration of quantum mechanics—the strange code of laws that governs the universe at its finest, subatomic scales.”
Researchers from MIT and Harvard have directly observed a quantum tornado, reports Elizabeth Gamillo for Smithsonian. “Scientists observed the tornado-like behavior after trapping and spinning a cloud of one million sodium atoms using lasers and electromagnets at 100 rotations per second,” writes Gamillo.
UPI reporter Brooks Hays writes that LIGO researchers have cooled a human-scale object to a near standstill. "One of the questions that we might be able to answer is: 'Why do large objects not naturally appear in quantum states?' There are various conjectures for why that might be; some say that gravity -- which acts strongly on larger objects -- might be responsible," explains Prof. Vivishek Sudhir. "We now have a system where some of these conjectures can be experimentally tested.”
LIGO researchers have nearly frozen the motion of atoms across four mirrors used to detect ripples in space-time, reports Isaac Schultz for Gizmodo. “We could actually use the same capability of LIGO to do this other thing, which is to use LIGO to measure the random jiggling motion of these mirrors—use that information which we have about the motion—and apply a counteracting force, so that you know you would stop the atoms from moving,” says Prof. Vivishek Sudhir.
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.
