Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal Quantum Information. To explain ...

We present a unified geometric and dynamical framework for a physical system consisting of n spin-1/2 particles with all-range Ising interaction. Using the Fubini-Study formalism, we derive the metric ...

What laws govern how chemicals pass through filters? How do droplets of oil move through layers of stone? How do blood cells travel through a living organism? A team of researchers led by the ...
