Plate F05 The Dilution Refrigerator

Chips & Information

Lithography machines and dilution refrigerators, and the fibres, satellites and codes that carry information.

  1. Plate 41 How a Phone Knows Where It Is InformationGoing further Thirty-odd satellites, 20,200 km up, keep announcing the time. A phone only listens, and from how late each announcement arrives it works out where it is, to within a few metres. Open
  2. Plate 42 Light in a Glass Thread InformationStart here Shine a light into a stream of water and the light bends with the stream. Today the same trick traps the internet in glass threads as fine as a hair and sends it across the Pacific. Open
  3. Plate 45 A Code That Survives Sand InformationStart here Bury part of a QR code in sand and a phone still reads it. The secret is in its spare bytes, which say nothing at all but can work out what went wrong and how to put it right. Open
  4. Plate F01 EUV Lithography Machine ManufacturingGoing further Light 13.5 nm long prints a chip’s circuits on silicon, four times smaller than the mask. It comes from tin droplets turned to plasma, and travels only by mirrors. Open
  5. Plate F05 The Dilution Refrigerator QuantumGoing further A superconducting quantum computer hangs from a gold-plated “chandelier”. Each stage is colder than the one above; the last is about 10 mK, hundreds of times colder than space. Open
