Cryptographers Discover a New Foundation for Quantum Secrecy
...to information security in the 1980s, a few researchers discovered that computational hardness wasn’t the only way to safeguard secrets. Quantum theory, originally developed to understand the physics of atoms,...
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...
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...
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...
The Physicist Working to Build Science-Literate AI
By training machine learning models with examples of basic science, Miles Cranmer hopes to push the pace of scientific discovery forward. Physics dazzled Miles Cranmer from an early age. His...
Solution: ‘Natural Law and Elegant Math’
...our object will continue to have a finite velocity and will therefore cover the distance in finite time. Hence, by the idealized laws of physics, the object will never stop,...
What’s the Magic Behind Graphene’s ‘Magic’ Angle?
...be fair, Jarillo-Herrero’s long, lonely hunt for interesting bilayer graphene physics at a 1.1-degree twist was inspired by a prediction of sorts: a guess, in a 2011 paper by Allan...
