Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction

In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...

Before North and South America were connected, their mammals found a way to intermingle

Until the Panamanian isthmus formed about 2.8 million years ago, North and South America were isolated continents with unique groups of animals. A riot of marsupials—mammals with brood pouches—and sloths in the south contrasted ...
