What Is Quantum Teleportation?
...thinking about other fundamental questions, including in condensed matter physics, where we’re trying to understand highly entangled states of quantum matter, and in gravitational physics. This story goes back a...
Machine Learning Gets a Quantum Speedup
Two teams have shown how quantum approaches can solve problems faster than classical computers, bringing physics and computer science closer together. For Valeria Saggio to boot up the computer in...
A Digital Copy of the Universe, Encrypted
...cues from the LHC on data handling, Jones said. Big Data in Physics Some past, present and future large-scale physics experiments and the number of petabytes (1015 bytes) of data...
Can Information Escape a Black Hole?
...with it is, it violates a principle of physics. The principle of physics is “nothing ever gets completely lost.” You say, well, that’s crazy. If I take a piece of...
An Italian Cosmologist Who Wanders in Dante’s Dark Wood
...about cosmology at all when I started physics, and even then I wasn’t very convinced about physics in itself. But physics offered me a good opportunity to combine several different...
Quantum Theory Rebuilt From Simple Physical Principles
...studied detached from its application to physics,” Chiribella said. This approach doesn’t address any underlying physics at all, but just considers how outputs are related to inputs: what we can...
What Is the Nature of Time?
...in the past? And how might quantum physics redefine it in the future? Frank is the Herman Feshbach Professor of Physics at M.I.T., a distinguished professor at Arizona State University,...
A New Map of the Universe, Painted With Cosmic Neutrinos
Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics. Of the 100 trillion neutrinos that pass...
Peering Into the Early Universe
...fields of astronomy, physics and cosmology. In addition to the planned experiments, scientists hope to be surprised by unforeseen, paradigm-shifting observations, the way a previous generation of four-meter telescopes discovered...
