Absolute zero inside is much cooler than Intel inside
IBM has shown off designs for cooling hardware it says will allow quantum computers to scale.Quantum computers rely on qubits – atoms or circuits put into a state of probability that means they can simultaneously store a value of zero and one – and which computer scientists make using complex circuitry or by suspending an atom with lasers. IBM produces qubits with chips that can only run at temperatures close to absolute zero. Big Blue’s quantum boxes therefore need serious cooling, and the company has to date made its fridges round and large.On Wednesday, the company revealed smaller, rectangular, modular cryogenic cabinets. The image below shows two of them holding some IBM quantum kit.

IBM says the boxes you see above are three times larger than a domestic fridge, are made of solid aluminum panels and framing, and provide “approximately 0.53 square meters of available wiring area and 2.75 cubic meters of vacuum chamber volume.” That’s enough space to hold “larger single processors and denser system configurations.”
