Using the smallest possible number of physical qubits to make a logical qubit is an important consideration in improving quantum computers. Honeywell didn't actually perform any computation during its demonstration, but showed that it could initialize the system, correct qubit errors during operations, and read the results afterward. Different aspects of QEC, including Honeywell's logical qubits, should enable more advanced algorithms. Quantum error correction is a method for detecting and fixing qubit errors so calculations can run longer. Seven of the qubits stored data while the remaining three 'ancilla' qubits shepherded the error correction process, which is governed by a conventional computer that steers qubits back on track when a problem is detected. Honeywell demonstrated its technique on its 10-qubit H1 quantum computer.

Quantum computers could crack today's encrypted messages.

Honeywell fires up the H1, its second-generation quantum computer.

Google quantum computer leaves old-school supercomputers in the dust.

Quantum computer makers like their odds for big progress.

That's why quantum computers typically run at extremely low temperatures in vibration-proof housings. The trouble is all qubits can be easily perturbed, and calculations are derailed when they are. Progress in the field, however, has been held back by the nature of qubits, which can be built and controlled in different ways. The prospect of channeling the power of quantum computers to commercial interests has triggered a gold rush as tech giants, such as Google, Intel and IBM, and startups race to develop practical machines. Honeywell's technique marks a significant step in the development of quantum computers, which have the potential to leapfrog ordinary computers in areas like materials science, manufacturing optimization and financial services.

'Big enterprise-level problems require precision and error-corrected logical qubits to scale successfully,' said Tony Uttley, Honeywell Quantum Solutions' president, in a statement.

That's why Honeywell is claiming its full error correction achievement as a first. Google's approach, however, didn't achieve full error correction: its method only could handle one of two error types at a time instead of both simultaneously, and it couldn't fix errors it detected. The results arrived one week after Google published a paper in Nature Communications also showing logical qubits overpowering errors. In a research paper released Wednesday, Honeywell said it had ganged together multiple physical qubits - the storage and processing units of quantum computers - so that they could withstand disturbances from outside forces like vibration and electromagnetic emissions. Honeywell and Google have detailed dueling demonstrations of logical qubits, a technology that can correct errors in potentially powerful but notoriously finicky quantum computers.
