Yes, they use superposition of the most "classical" quantum states (coherent states). These are called (Schrödinger) cat states, since his thought experiment was about a quantum superposition of a very classical object (a cat): https://en.wikipedia.org/wiki/Cat_state
It is theorized that CERN is powered by the bodies of dead physicists that turn in their graves every time someone brings up the Schroedinger cat to an audience that doesn't even know complex numbers.
There's also a smaller power section filled with computer scientists that turn when someone says that the quantum computer offers exponential speedups.
Guess why they named their chip Ocelot which is a big cat
The distinction between "big cats" and "small cats" is whether or not they purr. Ocelots and Cheetahs are wild "small cats" which can purr. Lions, tigers, panthers are "big cats" don't purr. There's a taxonomic distinction.
