Drawing a line between quantum and classical: Bell’s Inequality fails test as boundary
The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.
Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration
The award seeks to build upon recent successes of Sandia’s Magnetized Liner Inertial Fusion (MagLIF) concept. The concept uses a laser to heat fusion fuel contained in a small cylinder as it is compressed by the huge magnetic field of Sandia’s massive Z accelerator.
