Startup IonQ unveiled a quantum computer using an underlying trapped-ion technology similar to Honeywell’s in October that it said had an “expected quantum volume” of 4 million. Quantum volume is a measure of performance that takes into account several different variables. Honeywell also said it had achieved a quantum volume of 1,024, doubling its previous record announced just in March. Honeywell managed to achieve its real-time error correction by yoking together seven of the 10 physical qubits-the parts of a quantum computer that perform calculations-to form a single calculating unit, known as a “logical qubit.” “Big enterprise-level problems require precision and error-corrected logical qubits to scale successfully,” Tony Uttley, president of Honeywell Quantum Solutions, said in a statement. Errors are one of the things that is currently holding back many real-world applications of quantum computing. This is an advance on previous methods, in which such errors could only be spotted and corrected once a calculation had finished running, which made for potentially much slower processing times. Researchers at Honeywell Quantum Solutions, the company’s quantum computing division, demonstrated that it could correct in real time the errors that tend to creep into the calculations of today’s quantum computers, finding and correcting the mistakes as they occur. Honeywell will still own 54% of the new company and have the rights to use its technology, but the corporation will have the ability to raise additional outside financing. In June, the two companies announced the combination and that the merged company would be spun out from Honeywell as a stand-alone corporation.

Today’s announcement was also meant to showcase the promise of the merger of Honeywell’s quantum division, which has focused on quantum hardware, with Cambridge Quantum Computing, which has focused on software for quantum computers. Amazon is also reportedly assembling a team to build its own quantum hardware too. Honeywell’s quantum computer can be accessed through Microsoft’s Azure cloud-computing platform, although Microsoft has also been working on its own quantum computing hardware, which it has yet to perfect. The announcements were intended to show the extent to which Honeywell has emerged as a leader in the nascent quantum computing field, which has otherwise been dominated by big technology companies that are better known to consumers, such as Google and IBM. Industrial giant Honeywell and Cambridge Quantum Computing, a British software company Honeywell recently agreed to combine with its own quantum computing division, have announced a trio of big leaps forward in quantum computing performance.
