Is there a connection between Quantum AI and Elon Musk?
No, there is no connection.
There is also no way of making an AI on a quantum computer as there are not enough qubits in the current systems to even think about AI.
The idea of Quantum AI is just a way of climbing the Google search results pages by sensation and getting to the top on Google Search.
Other scams like Bitcoin Loophole are also on the rise, so be careful whenever you are online and do not pay any attention to ads that claim they can make you rich or teach you to trade in minutes.
