So allegedly most of what we see here is temperature control.
The qubits are stored in a chip in the bottom. Normal electronic stuff is at the top.
Each (circle) layer is kept at a different specific temperature. The normal electronic signals start at room temperature and cascade to lower and lower temperatures to interact with the qubits. The “reply” then cascades back up.
Most of that is the helium dilution refrigerator. Most electronic quits work at near absolute zero, so all of what you see here is wiring for the quantum computer (all those co-ax cables) and the equipment needed to manipulate the helium mixture to cool things down (you need the right mixture of helium isotopes because they boil at different temperatures so boiling away one isotope allows the remaining isotope to get even colder).
