Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, but time keeps moving. That assumption sits so deep in modern science that it ...

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...
