A surreal collage: a portrait of PsiQuantum co-founder Peter Shadbolt, his face cut away to a window onto a chip-fabrication cleanroom where a worker in a white suit walks down the aisle, inside an arch of orange storm clouds against a night sky of cumulonimbus over a treeline.

The Record So Far

What quantum companies said they would deliver, and when it came.

A torn-paper collage portrait of cryptographer Matthew Green. A gold quantum-computer chandelier hangs from the crown of his head, over the page edges of the Voynich manuscript, a gilded horse weather vane, a Girodet pen sketch and red and blue paper; one of his eyes and his mouth show through, and a purple protein model takes the place of the other eye. Behind him a space shuttle lifts off, and red bars beside him read: We might lose public key cryptography!
