A wormhole is a tunnel through space, connecting distant regions of the Universe. Its shadow against a bright gas background was long thought to be as round as that of a black hole. But for a rotating wormhole (one you could actually traverse), the shape of the shadow might be surprising: the edge becomes jagged, like a gear.

A quantum processor is like a busy intersection: the more cars, the harder it is for them to navigate without collisions. In the quantum world, qubits play the role of cars — elementary carriers of information that, unlike classical bits, can be both 0 and 1 simultaneously.
