Prof. Peter Shor speaks with Katia Moskvitch and her nine-year-old son Kai of The Quantum Kid about how quantum technologies could be applied to developing climate change and sustainability solutions. Shor explains that quantum computers can be used for “simulating quantum mechanics, which would really help immensely in designing new materials, and new materials could be very useful for solving the climate crisis.”
Prof. Emeritus Daniel Kleppner, “an experimental physicist who helped to develop an atomic clock that became an essential part of global positioning systems (GPS),” has died at the age of 92, reports Dylan Loeb McClain for The New York Times. In addition to his work in atomic clocks, Kleppner also “helped to discover a rare fundamental state of matter predicted by Albert Einstein and his fellow theoretical physicist Satyendra Nath Bose,” writes McClain.
Prof. Emeritus Daniel Kleppner, a “highly honored physicist who developed technologies that helped pave the way for the Global Positioning System and whose foundational atomic discoveries helped open up the field of quantum computing,” has died at age 92, reports Anusha Mathur for The Washington Post. Prof. Wolfgang Ketterle explains that Kleppner’s research laid the groundwork for what “in the last 15 years has been developed into a new platform, a new approach for quantum computation. That has led to multimillion-dollar funding in multiple start-up companies in Europe and the U.S.”
Jia Haojun PhD '24, graduate student Gao Wenhao and postdoctoral associate James Utama Surjadi have been named to the Forbes 30 and Under 30 Asia: Healthcare & Science list, writes Yue Wang for Forbes. The list honors those “who are using cutting-edge technology to innovative and improve their industry.”
MIT researchers have developed a superconducting circuit that can increase the speed of quantum processing, reports Aamir Khollam for Interesting Engineering. “This device is a superconducting circuit designed to produce extremely strong nonlinear interactions between particles of light (photons) and matter (qubits),” explains Khollam. “This breakthrough could make operations up to 10 times faster, bringing fault-tolerant, real-world quantum computing a major step closer.”
Researchers at MIT believe they have demonstrated the strongest non-linear light-matter coupling in a quantum system, reports Bill Bell for Quantum Campus. “Their novel superconducting circuit architecture showed coupling about an order of magnitude stronger than prior demonstrations,” writes Bill. “It could significantly improve the measurements and error corrections needed to increase the accuracy and reliability of quantum computers.”
MIT researchers have made a key advance in the creating a practical quantum computer by demonstrating “remote entanglement—an essential step in building distributed quantum networks—by sending photons between two quantum processors,” reports Military & Aerospace Electronics. “This breakthrough lays the groundwork for large-scale quantum computing networks and could extend to other quantum computing platforms and the quantum internet.”
Rachel Feltman of Scientific American’s “Science Quickly” podcast visits MIT.nano to learn more about MIT’s “clean laboratory facility that is critical to nanoscale research, from microelectronics to medical nanotechnology.” Prof. Vladimir Bulović, director of MIT.nano, explains: “Maybe a fifth of all of M.I.T.’s research depends on this facility…from microelectronics to nanotechnology for medicine to different ways of rethinking what will [the] next quantum computation look like. Any of these are really important elements of what we need to discover, but we need all of them to be explored at the nanoscale to get that ultimate performance.”
Prof. Seth Lloyd speaks with Fast Company reporter Sam Becker about quantum computing firm D-Wave and their recent work successfully simulating “the properties of magnetic materials.” Lloyd explains: “The D-Wave result shows the promise of quantum annealers for exploring exotic quantum effects in a wide variety of systems.”
Nature reporter Elizabeth Gibney spotlights QuEra, an MIT spinout that uses atoms and lasers to encode quantum bits or “qubits.” Gibney notes that in the QuEra system, “physicists trap an array of rubidium atoms using laser light and store quantum information in the energy levels of their electrons.”
MIT physicists have measured kinetic inductance for two layers of stacked and twisted graphene and found that the superconducting current is much “stiffer,” meaning it resists change more than predicted by any conventional theory of superconductivity, reports Karmela Padavic-Callaghan for New Scientist. The findings could do more than “shed light on why graphene superconducts – they could also reveal key properties required for room-temperature superconductors.”
MIT engineers have developed “two new control techniques that have enabled them to achieve a world-record single-qubit fidelity of 99.998 percent using a superconducting qubit called fluxonium,” reports Aman Tripathi for Interesting Engineering. “This breakthrough marks a significant step towards the realization of practical quantum computing,” Tripathi notes.
Physics World has selected two research advances by MIT physicists for its Top 10 Breakthroughs of the Year for 2024, reports Hamish Johnston for Physics World. Graduate student Andrew Denniston and his colleagues were honored for their work “being the first to unify two distinct descriptions of atomic nuclei,” which Johnston describes as a “major step forward in our understanding of nuclear structure and strong interactions.” MIT researchers were also featured for their work demonstrating quantum error correction on an atomic processor with 48 logical qubits, making it “far more likely that quantum computers will become practical problem-solving machines.”
Prof. Seth Lloyd speaks with NPR Morning Edition host Adam Bearne about recent advancements in quantum chips and the future of quantum computing. "Quantum computers, their ability to do multiple tasks at once, allows them to explore a much larger range of possibilities than is available to classical computers, which can really only do one thing at a time," says Lloyd.
A team of MIT researchers discovered a hard limit for the “spooky” phenomenon known as quantum entanglement, reports Ben Brubaker for Quanta Magazine. The researchers found that quantum entanglement does not weaken as temperatures increase, but rather it vanishes above specific temperatures, a behavior dubbed the “sudden death” of entanglement. “It’s a very, very strong statement,” says Prof. Soonwon Choi of the findings. “I was very impressed.”
