Quantum computers are already small — it's the cryogenics that take up all the space

Blogger craigmullins shares a firsthand observation from IBM TechXchange, correcting a common misconception: quantum computers themselves are already pretty small. The bulk of the footprint comes from the cryogenics — dilution refrigerators that cool the superconducting chip to near absolute zero are what make the whole rig look enormous.
A neat piece of on-the-ground trivia.
