MIT researchers have found a way to amplify the signals from particles in quantum relationships to make them easier to read, reports Juandre for Popular Mechanics. “Their method could lead the way to better measurements of many tiny phenomena, from atomic clocks to the search for elusive dark matter,” writes Juandre.
Professor William Oliver, graduate students Bharath Kannan and Tim Menke, Principal Research Scientist Simon Gustavsson, Shereen Shermak MBA ’97, Youngkyu Sung PhD ’22, and former research scientist Jonas Bylander founded Atlantic Quantum, a company that aims to improve the basic hardware behind quantum computing, reports Ariyana Griffin for Forbes. “The focus on Atlantic Quantum is building hardware that improves the ‘coherence’ of quantum computation, which reduces the errors that are the major speed bump for these machines,” writes Griffin.
Fast Company reporter Mark Sullivan spotlights QuEra Computing as one of the 15 startups to watch in 2022. “Research breakthroughs by scientists at the Massachusetts Institute of Technology and Harvard University led to the launch of QuEra Computing, which uses a unique quantum architecture and laser techniques to arrange and direct the tiny qubits or quantum bits, in its 256-qubit system,” writes Sullivan.
MIT researchers are developing innovations aimed at improving Covid-19 diagnostics, including an atomic-level test designed to increase testing accuracy, reports Steven Zeitchik for The Washington Post. Professor James Collins and his team are developing “a mask that uses freeze-dried technology to detect the coronavirus.”
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.”
President L. Rafael Reif speaks with Sabri Ben-Achour of Marketplace about the importance of the Senate passing a new bill that invests in research and development. “We are in a science and technology race for the future,” says Reif. “It is with science and technology that we address things like Covid and the biggest challenges the world has; the health of our economy, our security. That is key to all of the above.”
Symmetry Magazine reporter Sarah Charley writes that a new study co-authored by MIT postdoc Xiaojun Yao examines how quantum computing could advance our understanding of quantum processes. Yao explored how “the properties of a heavy particle could be impacted after it traversed through a quark-gluon plasma,” and after several months of testing was able to “demonstrate that these kinds of calculations are already feasible on today’s quantum computers.”
Researchers from MIT Lincoln Laboratory have developed a new quantum chip with integrated photonics, a “vital step to advance the evolution of trapped-ion quantum computers and quantum sensors,” reports Paul Smith-Goodson for Forbes.
Forbes contributor Elizabeth Fernandez writes that a study co-authored by MIT researchers shows quantum entanglement could give blackjack players a slight edge. Fernandez adds that the research shows how, “entangled systems can show up in our macroscopic, everyday lives.”
Writing for Quanta Magazine, David Freedman spotlights Prof. Pablo Jarillo-Herrero’s discovery that when twisted to a “magic” angle, graphene can act as a semiconductor. Freedman writes that the “discovery has given scientists a relatively simple platform for exploring exotic quantum effects.”
Prof. Pablo Jarillo-Herrero speaks with Gizmodo reporter Ryan Mandelbaum about his work showing that when twisted to the right angle, graphene can serve as an insulator or semiconductor. “This sort of field of ‘twistronics’ is something with great potential in terms of scientific discovery and intellectual interest,” Jarillo-Herrero explains.
Nature reporter Elizabeth Gibney spotlights Prof. Pablo Jarillo-Herrero’s discovery that graphene can act as a superconductor when twisted to a magic angle. “I haven’t seen this much excitement in the graphene field since its initial discovery,” said ChunNing Jeanie Lau, a professor at Ohio State University, of the impact of Jarillo-Herrero’s findings.
Prof. Pablo Jarillo-Herrero’s discovery that when graphene is rotated to a “magic angle” it can act as a high-temperature superconductor has been named the Physics World 2018 Breakthrough of the Year. Physics World reporter Hamish Johnston writes that the “discovery led to the development of ‘twistronics’, which is a new and very promising technique for adjusting the electronic properties of graphene.”
Writing for The New Yorker, Prof. David Kaiser contrasts a new study in Nature, which concludes that “if human will is free, there are physical events… that are intrinsically random, that is, impossible to predict,” with the 19th century writings of Stephen Freeman, who argued that, “human consciousness and our perception of free will must be subject to chains of causation.” The researchers, says Kaiser, “turned Freeman’s formulation on its head.”
