IBM has 1000 qubits on their roadmap by 2023 [1]. I'm interested to see how that goes, and what we can learn from it about scaling up these systems into the thousands of qubits.
Edit: for anyone interested in learning more about quantum computation, I have a list of resources on my website [2].
Since I didn't see it mentioned, I assume those are 1000 noisy qubits, so they'll require error correction. I wonder how many ideal qubits they are equivalent to.
