Quantum computers hold the promise of performing certain tasks that are intractable even on the world’s most powerful supercomputers. In the future, scientists anticipate using quantum computing to em...
New approach may help clear hurdle to large-scale quantum computing（图）
量子计算 量子处理器 穿梭纠缠 可编程量子机器
2023/6/21
Building a plane while flying it isn’t typically a goal for most, but for a team of Harvard-led physicists that general idea might be a key to finally building large-scale quantum computers.
Physicists bring human-scale object to near standstill, reaching a quantum state（图）
量子态 引力 原子尺度
2023/6/19
To the human eye, most stationary objects appear to be just that — still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, wha...

Scientists Report Large-Scale Surface Melting Event in Antarctica during 2015-16 El Nino
Scientists Large-Scale Surface Melting Event Antarctica 2015-16 El Nino
2017/7/21
The West Antarctic Ice Sheet, a landbound mass of ice larger than Mexico, experienced substantial surface melt through the austral summer of 2015-2016 during one of the largest El Niño events of ...
Changes in precipitation patterns influence natural selection at global scale
precipitation patterns natural selection global scale
2017/3/14
What matters more for the evolution of plants and animals, precipitation or temperature? Scientists have found a surprising answer: rain and snow may play a more important role than how hot or cold it...

Barrier-island migration drives large-scale marsh loss
2017/2/16
If you’ve visited the Outer Banks or other barrier islands, you’ve likely experienced their split personalities—places where high waves can pound the sandy ocean shore while herons stalk placid saltma...
Spintronics advance brings wafer-scale quantum devices closer to reality
Spintronics advance wafer-scale quantum devices
2015/7/13
An electronics technology that uses the “spin”—or magnetization—of atomic nuclei to store and process information promises huge gains in performance over today’s electron-based devices. But getting th...
Scientists Are First to See Elements Transform at Atomic Scale
Scientists Elements Transform Atomic Scale
2015/6/18
Chemists at Tufts University’s School of Arts and Sciences, collaborating with PerkinElmer and UCL (University College London), have witnessed atoms of one chemical element morph into another for the ...
Formation and large-scale confinement of jets emitted by young stars finally elucidated
young stars plane scientists
2014/10/30
An international team of scientists has succeeded in explaining the formation and propagation over astronomical distances of jetsof matter emitted by young stars—one of the most fascinating mysteries ...
MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram — one millionth of a trillionth of a gram. Weighing these tiny particles, including both syn...
'Killer' Southeast Drought Low on Scale, Says Study--Others Were Far Worse; Population, Planning Are the Real Problems（图）
'Killer' Southeast Drought Population Planning the Real Problems
2009/12/10
A 2005-2007 dry spell in the southeastern United States destroyed billions of dollars of crops, drained municipal reservoirs and sparked legal wars among a half-dozen states—but the havoc came not fro...
Physicists have drawn up ambitious plans to detect very low-frequency gravitational waves – ripples in the fabric of space–time that general relativity predicts ought to pervade the universe. But rath...
