Eternal Change for No Energy: A Time Crystal Finally Made Real

Quanta Magazine: In a preprint posted online Thursday night, researchers at Google in collaboration with physicists at Stanford, Princeton and other universities say that they have used Google’s quantum computer to demonstrate a genuine “time crystal.” In addition, a separate research…

Fractons, the Weirdest Matter, Could Yield Quantum Clues

Wired: Your desk is made up of individual, distinct atoms, but from far away its surface appears smooth. This simple idea is at the core of all our models of the physical world. We can describe what’s happening overall without…

Google’s Quantum Computer Exponentially Suppresses Errors

IEEE Spectrum: In order to develop a practical quantum computer, scientists will have to design ways to deal with any errors that will inevitably pop up in its performance. Now Google has demonstrated that exponential suppression of such errors is possible,…

Quantum chemical reaction behind birds’ internal compass

Chemistry World: Researchers have discovered a radical-pair reaction in the eyes of migrating robins that could explain how the birds use Earth’s magnetic field to navigate. Covering up to 200miles (320km) per night, some UK robins – not all of which…
