The amount of cooling they need for a simple quantum CPU with 104 qubits. Can you even do anything with it that is useful, you can’t even brake encryption because you don’t have enough processing power.
The science is advancing, but then as always is the question of, how you scale it to be economical viable, which is a hard problem by it self to solve.
Don’t think the market is interested in tech that they can’t hype, or have a natural hype cycle.

I would be surprised. Quantum computers haven’t even been proven to be theoretically useful.
