Major Quantum Computing Strategy Suffers Serious Setbacks
...Nature in April. Yet despite this problem, even the field’s critics find the science too promising to ignore. “The physics behind the creation of Majoranas is well understood theoretically,” said...
Tadashi Tokieda’s Special Kind of Magic
...the world in a toy. Tadashi sees in toys, — just like children’s toys, little playthings — the whole universe that’s in there, the principles of physics. He is a...
Neutrinos Hint of Matter-Antimatter Rift
An early sign that neutrinos behave differently than antineutrinos suggests an answer to one of the biggest questions in physics. As neutrinos and antineutrinos change flavors they may illuminate the...
Beyond the Second Law
...law of thermodynamics has reigned over physics, chemistry, engineering and biology. Now, an upgrade is underway. Thermodynamics — the study of energy — originated during the 1800s, as steam engines...
Toward a Grand Unified Theory of Snowflakes
Snow crystals come in two main types. The “pope” of snowflake physics has a new theory that explains why. Kenneth Libbrecht is that rare person who, in the middle of...
Mass and Angular Momentum, Left Ambiguous by Einstein, Get Defined
...mathematical physicist Roger Penrose, another pioneer of black hole physics, identified the task of characterizing quasilocal mass — “where one does not need to go ‘all the way to infinity’...
Particle Physicists Puzzle Over a New Duality
A hidden link has been found between two seemingly unrelated particle collision outcomes. It’s the latest example of a mysterious web of mathematical connections between disparate theories of physics. Last...
Physicists Rewrite a Quantum Rule That Clashes With Our Universe
...of Harvard University have collaborated on an effort to replace unitarity in quantum physics with an alternative rule called isometry. Bianca Dittrich, of the Perimeter Institute for Theoretical Physics, struck...
Quantum Machine Appears to Defy Universe’s Push for Disorder
...Lukin said they observed. The system seems to be imbued with some special physics that allows it to retrace its path, Papić said. “It leaves bread crumbs and goes back...
