Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in ...

Quantum link: New research has revealed an unexpected connection between the physics of approximate error-correcting codes and quantum gravity. (Courtesy: Shutterstock/Evgenia Fux) In computing, ...

Errors such as noise cause a damping of the signal relative to the ideal case. Finite- rate quantum error correction can recover substantial parts of the lost signal ...

Before the dream of quantum computing is realized, a number of inherent problems must first be solved. One of these is the ability to maintain a stable memory system that overcomes the intrinsic ...

Adam Riess was sure he’d spotted a blatant error in his results. It was 1997, and the young post-doc’s measurements of distant, exploding stars implied that the ...

Quantum computers could outperform classical computers at many tasks, but only if the errors that are an inevitable part of computational tasks are isolated rather than widespread events. Now, ...

EXTRA dimensions. Time travel. Tachyons. These ideas seemed a little more likely in the wake of claims that subatomic particles called neutrinos had moved faster than light – violating a cornerstone ...
