A Quantum of Solace: Resolving a Mathematical Puzzle in Quarks and Gluons in Nuclear Matter — Scientists have taken a si |
. These particles interact via the “strong” force, one of the four fundamental forces of nature. They make up the nuclei at the heart of every. They also make up forms of hot or dense nuclear matter that exhibit exotic properties. Scientists study the properties of hot and cold nuclear matter in relativistic heavy ion collision experiments and will continue to do so using the future Electron-Ion Collider.
Researchers at the Massachusetts Institute of Technology and the University of Washington have now found this implication to be incorrect. The study also carefully analyzed the subtle conditions for when axial gauge can be employed and explained why the two properties are different. Finally, it showed that two distinct methods for measuring how gluons are distributed inside nuclei must yield different results.

Demonstration of Algorithmic Quantum SpeedupDespite the development of increasingly capable quantum computers, an experimental demonstration of a provable algorithmic quantum speedup employing today's non-fault-tolerant devices has remained elusive. Here, we unequivocally demonstrate such a speedup within the oracular model, quantified in terms of the scaling with the problem size of the time-to-solution metric. We implement the single-shot Bernstein-Vazirani algorithm, which solves the problem of identifying a hidden bitstring that changes after every oracle query, using two different 27-qubit IBM Quantum superconducting processors. The speedup is observed on only one of the two processors when the quantum computation is protected by dynamical decoupling but not without it. The quantum speedup reported here does not rely on any additional assumptions or complexity-theoretic conjectures and solves a bona fide computational problem in the setting of a game with an oracle and a verifier.
