What is it actually like to visit a quantum computing facility? Anyone been to IBM, Google, or IonQ labs?

With quantum computing increasingly in the news, IBM opening their Chicago hub, IonQ opening 22,000 sq ft in Boulder, and the Anderon foundry in Albany being announced, I am curious about the physical reality of these places.

Has anyone here visited a quantum computing facility, attended an open day, or worked in one? What is the actual physical environment like? The dilution refrigerators, the laser systems, the control electronics? It seems like these machines must be extraordinary to see in person

Visited the IBM Q Network lab at Oxford a few years ago. The dilution refrigerator looks like a chandelier made of concentric rings descending to the chip at the bottom. The whole thing is suspended on vibration isolation. The room is extremely quiet

The control electronics are what surprised me most. For every qubit there are multiple coaxial cables carrying microwave pulses and measurement signals. A 100-qubit system has more cable than the machine itself

Trapped-ion facilities are different. The vacuum chamber where the ions live is smaller than you expect. The laser systems are what dominate the room. Dozens of laser beams precisely aligned through optical fibre and free space

The cryostat operating temperature of 10-20 millikelvin is colder than outer space. The universe has a background temperature of 2.7 Kelvin. These machines operate 200 times colder than that

IBM has done quantum experience tours where researchers can visit their facilities. Worth checking whether they are running again in 2026 post the Anderon foundry announcement

The most striking thing for me was the silence. Quantum hardware is sensitive to vibration and electromagnetic interference so the facilities are designed to be as quiet and isolated as possible. It feels like a physics lab crossed with a data centre crossed with a clean room
