It's possible human thought leverages quantum processes. That doesn't mean it's likely.
DDG’s bot’s summary of the linked article and one other:
“The computational power of the human brain is often estimated in floating-point operations per second (FLOPS), with estimates ranging from 10^12 to 10^28 FLOPS, depending on the level of detail considered. In comparison, modern supercomputers can perform up to several hundred petaflops, but the brain is believed to operate at a similar or even higher efficiency due to its unique structure and processing capabilities.”
Neither the article nor the paper discuss consciousness, only biological computing capacity considering quantum states.

Today's classical computing accomplishments are impressive, but nowhere near what a human can do. Perhaps someday soon a single AI could (in the words of Heinlein) "change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly" but that day is not yet here. If we struggle to build such a device, we might consider that our computers are too limited.
