Yes. The researchers at IBM don't use the number of qubits as a measure of the quality of the computer. They use the quantum volume [0]. I said 50 qubits because I was just parroting the press release. The reason I didn't mention D-Wave's machine is because it is not a universal quantum computer. It is a quantum annealer [1].
Google and IBM want their qubits to be of high quality (high coherence times e.t.c). One of the big obstacles right now is scaling up the number of qubits while making sure that their quality is high.
