Nobel Prize in Physics Is Awarded for Work in Quantum Mechanics

4 months 1 week ago
The New York Times: John Clarke, Michel H. Devoret and John M. Martinis were awarded the Nobel Prize in Physics on Tuesday in Sweden for showing that two properties of quantum mechanics, the physical laws that rule the subatomic realm, could be observed on a system large enough to see with the naked eye. They will share a prize of 11 million Swedish kroner, or around $1.17 million. "There is no advanced technology today that does not rely on quantum mechanics," Olle Eriksson, chairman of the Nobel Committee for Physics, said during the announcement of the award. The laureates' discoveries, he added, paved the way for technologies like the cellphone, cameras and fiber optic cables. It also helped lay the groundwork for current attempts to build a quantum computer, a device that could compute and process information at speeds that would not be possible with classical computer. Martinis worked at Google from 2014 to 2020 to build a quantum computer and led the quantum supremacy experiment in 2019. Devoret is cited in Google's recent breakthrough where its Willow quantum chip solved a problem in five minutes that the world's most advanced supercomputer could never solve. The three laureates conducted experiments with electrical circuits that demonstrated quantum mechanical tunneling and quantized energy levels in systems large enough to hold in the hand. Clarke is a professor at the University of California, Berkeley. Devoret joined his research group in the 1980s and is now at Yale University and UC Santa Barbara. Martinis also joined the group in the 1980s and is currently at UC Santa Barbara and co-founded Qolab, a startup developing utility-scale superconducting quantum computers.

India's Grid Cannot Keep Up With Its Ambitions

4 months 1 week ago
India's electricity grid is struggling to accommodate the nation's economic expansion and isn't adequately equipped to handle future data center demand. Goldman Sachs estimates that power required from utilities needs roughly 7.2% annual growth between fiscal years 2025 and 2035, up from a prior 5.6%. India's data center base sits in the low single gigawatts today, but Bernstein forecasts reach 5 to 6 gigawatts by 2030. AI servers draw five to seven times the power of a legacy server rack, according to HSBC. Solar farms can be built in 12 to 24 months, but they flood the grid when daytime demand is comparatively low and then fade as households and commercial loads climb after 5 PM. On Goldman's full-year models, the system runs a 1 to 4% energy deficit by fiscal years 2034 through 2035. Assessments suggest India may need roughly 140 gigawatts of additional coal capacity by fiscal year 2035 versus 2023 levels. The government's current target is roughly 87 gigawatts by fiscal year 2032. Coal plants can run around the clock and can ramp up production during the evening hours to meet surging demand. Some of this coal is bridge capacity to stabilize a faster greening grid, but the scale required exceeds what policymakers have publicly acknowledged or what most analysts expected even two years ago.
