MIT researchers have developed a security protocol that utilizes quantum properties to ensure the security of data in cloud servers, reports Andrew Corselli for Tech Briefs. “Our protocol uses the quantum properties of light to secure the communication between a client (who owns confidential data) and a server (that holds a confidential deep learning model),” explains postdoc Sri Krishna Vadlamani.
Science reporter Jennifer Sills asked scientists to answer the question: “Imagine that you meet all of your research goals. Describe the impact of your research from the perspective of a person, animal, plant, place, object, or entity that has benefited from your success.” Xiangkun (Elvis) Cao, a Schmidt Science Fellow in the MIT Department of Chemical Engineering, shares his response from a photon’s perspective. “I am a photon,” writes Cao. “I started my journey entangled with my significant other at the beginning of the Universe. In the past, humans couldn’t understand me, but then physicists created a quantum computer. At last, I have been reunited with my life partner!”
MIT researchers devised a new way to arrange LED pixels to create screens with a much higher resolution than is currently possible, reports The Economist. The new technique, which involves stacking micro LEDS, could also be used to make “VR images that appear far more lifelike than today’s.”
Research scientist Ryan Hamerly and his team are working to harness “the low power consumption of hybrid optical devices for smart speakers, lightweight drones and even self-driving cars,” reports The Economist.
Researchers at MIT have “created a stretchable color-changing material based on how nature often reflects color,” reports Nicole Estaphan for WCVB’s Chronicle. “As you stretch it, these embedded nanostructures change size,” explains graduate student Benjamin Miller, “which in turn changes the color of light that comes back. We are making an elastic, squishy version of the sort of thing you find in nature.”
MIT researchers have developed “a programmable wireless device that can control light orders of magnitude more quickly than commercial devices,” reports Susannah Sudborough for Boston.com. “The device, which is called a spatial light modulator (SLM), will have impactful practical uses beyond creating holograms,” writes Sudborough.
Alexander Sludds, a graduate student in MIT’s Research Lab for Electronics, joins Megan Cantwell on the Science magazine podcast to discuss his team’s new method for processing data on edge devices, which are devices that connect two networks together.
Popular Science reporter Charlotte Hu writes that MIT researchers have developed an “electronics chip design that allows for sensors and processors to be easily swapped out or added on, like bricks of LEGO.” Hu writes that “a reconfigurable, modular chip like this could be useful for upgrading smartphones, computers, or other devices without producing as much waste.”
MIT engineers have developed a wireless, reconfigurable chip that could easily be snapped onto existing devices like a LEGO brick, reports Miriam Fauzia for The Daily Beast. “Having the flexibility to customize and upgrade an old device is a modder’s dream,” writes Fauzia, “but the chip may also help reduce electronic waste, which is estimated at 50 million tons a year worldwide.”
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.
A number of MIT researchers were named as top ten finalists for the Physics World 2021 Breakthrough of the Year. Prof. Wolfgang Ketterle and his colleagues were honored for their work in “independently observing Pauli blocking in ultracold gases of fermionic atoms” and astronomers with the Event Horizon Telescope Collaboration were honored for “creating the first image showing the polarization of light in the region surrounding a supermassive black hole.”
Edgar Herwick of GBH News visits the lab of Prof. Mathias Kolle to explore the science behind what causes rainbows to arc across the sky. “The sun has to be behind you. Then water in the atmosphere in front of you. And that's usually when it rains, you get that condition,” says Kolle. “Then what you also want to do is you want to look at the right spot.”
Scientists from MIT have observed a quantum effect that blocks ultracold atoms from scattering light, reports Emily Conover for Science News. To observe the effect, the researchers “beamed light through a cloud of lithium atoms, measuring the amount of light it scattered,” writes Conover. “Then, the team decreased the temperature to make the atoms fill up the lowest energy states, suppressing the scattering of light.”
A new study by MIT scientists has uncovered evidence of Pauli blocking, confirming that as atoms are chilled and squeezed to extremes their ability to scatter light is suppressed, reports Leah Crane for New Scientist. “This is a very basic phenomenon, but it’s sort of a devil to see,” explains former MIT postdoc Yair Margalit. “You need these extreme conditions to be able to see it – high densities and ultra-low temperatures – and it is difficult to get both of these at once.”
