The media claims less that a 100 qubits is really good for quantum computers:
Prototype quantum computers made of a few dozen qubits have materialized in the last couple of years, led by Google’s 54-qubit Sycamore machine.
IBM has built the largest quantum computer yet. Dubbed Osprey, it has 433 qubits, or quantum bits, which is more than triple the size of the company’s previously record-breaking 127-qubit computer and more than eight times larger than Google’s 53-qubit computer Sycamore.
Just as you know the media gets almost everything wrong about guns, they don’t know quantum computing either. This is what one company is saying publicly:
Photonic is producing 2cm square silicon chips capable of holding a million+ qubits.
I won’t tell you how long ago I knew this, what they are saying now, and what hints have been dropped about the future other than what I said yesterday. But the business model will be, basically, a “mainframe which you can rent time on.” The computer languages already exist to write quantum programs.
I recently asked another source with in depth knowledge of the state of the art in quantum computing, “I know about decryption, but what are going to be the other ‘killer apps’ for quantum computing?” The answer was, “Solutions to logistics problems, weather and climate modeling, and anything with really large numbers of variables.”
