A Tricky Path to Quantum-Safe Encryption
...years. By exploiting the probabilistic rules of quantum physics, the devices could decrypt most of the world’s “secure” data, from NSA secrets to bank records to email passwords. Aware of...
‘Outsiders’ Crack 50-Year-Old Math Problem
...different to Kalai. It seemed connected to the famous Kadison-Singer problem, a question about the foundations of quantum physics that had remained unsolved for almost 50 years. Over the decades,...
Gravitational Waves Discovered at Long Last
...make waves in space-time. Rainer Weiss, a professor of physics at the Massachusetts Institute of Technology, around 1970. Still, Einstein and his colleagues continued to waffle. Some physicists argued that...
LIGO Reports Second Black-Hole Merger
...professor of physics at Syracuse University, told Quanta that the two observations to date “tell us the black holes exist over a broad range of masses, from about seven to...
Colliding Black Holes Tell New Story of Stars
...universe, akin, some said, to when Galileo first pointed a telescope at the sky. Already, the new gravitational-wave data has shaken up the field of astrophysics. In response, three dozen...
Tiny Tests Seek the Universe’s Big Mysteries
...of exotic physics that could be visible at scales just below the thickness of a dollar bill — provided you build a clever-enough experiment, one small enough to fit on...
Priya Natarajan on Black Holes and Mapping the Universe
...you know, like, a very sort of strong sense of being grounded in physics and foundations of physics and mathematics. And, so, I often come up with a diagram, like,...
‘Next-Level’ Chaos Traces the True Limit of Predictability
...mathematics and computer science. But he never forgot the pinball machine, and how computer science put limits on the machine’s physics. He wondered whether undecidability touched any physics problems that...
Quantum Complexity Shows How to Escape Hawking’s Black Hole Paradox
...foundations of most modern theories, including the celebrated Standard Model of particle physics. Physicists expect semiclassical physics to falter when gravity grows intense, as it does at the still-inscrutable center...
