IBM pushes qubit count over 400 with new processor

Today, IBM announced the latest generation of its family of avian-themed quantum processors, the Osprey. With more than three times the qubit count of its previous-generation Eagle processor, Osprey is the first to offer more than 400 qubits, which indicates the company remains on track to release the first 1,000-qubit processor next year.
Despite the high qubit count, there's no need to rush out and re-encrypt all your sensitive data just yet. While the error rates of IBM's qubits have steadily improved, they've still not reached the point where all 433 qubits in Osprey can be used in a single algorithm without a very high probability of an error. For now, IBM is emphasizing that Osprey is an indication that the company can stick to its aggressive road map for quantum computing, and that the work needed to make it useful is in progress.
