Honeywell and Google gave a detailed duel demonstration of logical cubits. This is a technology that can fix potentially powerful but notorious nasty errors. Quantum computer..
and Research treatise Honeywell, released Wednesday, said it combined multiple physical qubits (quantum computer storage and processing units) to withstand disturbances from external forces such as vibrations and electromagnetic radiation.

Results arrived a week later Google publishes a treatise Nature Communications also shows the logical cubits that overwhelm the error. However, Google’s approach did not achieve complete error correction. That method could only handle one of the two error types at a time, rather than both at the same time. Could not fix the error detected.. That’s why Honeywell first claims the results of complete error correction.
“Scaling large enterprise-level problems successfully requires precision and error-corrected logical qubits.” Tony Atley said, President of Honeywell Quantum Solutions, in a statement.
Honeywell’s technology represents an important step in the development of quantum computers that have the potential to make a leap forward in ordinary computers in areas such as materials science, manufacturing optimization, and financial services. As tech giants and start-ups such as Google, Intel and IBM compete for the development of practical machines, the prospect of turning the power of quantum computers into commercial profits has sparked the gold rush.
However, progress in this area has been hampered by the nature of qubits, which can be constructed and controlled in a variety of ways. The problem is that all qubits can easily be perturbed, which derails the calculation. As a result, quantum computers typically operate at very low temperatures inside anti-vibration housings.
Honeywell uses that technology 10 qubit H1 quantum computer.. Seven of the qubits stored the data and the remaining three “auxiliary” qubits managed the error correction process. The error correction process is controlled by a traditional computer that puts the cubit back into orbit when a problem is detected.
Realization of quantum error correction
Quantum error correction is a method of detecting and correcting qubit errors so that calculations can be performed longer. Various aspects of QEC, including Honeywell’s logical qubits, should allow for more sophisticated algorithms.
Honeywell didn’t actually perform the calculations during the demonstration, but showed that it could initialize the system, fix qubit errors during operation, and read the results later.
Creating logical qubits with as few physical qubits as possible is an important consideration in improving quantum computers. Today’s machines have only a few tens of qubits at most, and many expect quantum computers to need thousands of logical qubits to really be useful. Google said in May that it expects to need about 1,000 physical qubits for each logical qubit. Providing a practical quantum computer by 2029..
All other quantum computing companies are also trying to improve qubit operations. The work involves not only error correction, but also making the qubits less prone to error in the first place, increasing the time it takes for multiple qubits to be entangled and performing calculations, and after the calculation is complete. It also includes correcting errors. Even Amazon Quantum computing service called bracket However, it has not announced its own quantum computer. Working on error correction ideas..
New honeywell quantum computer on the way
Honeywell manufactures quantum computers such as H0 and H1 that use ytterbium charged atoms as qubits that can be manipulated by a laser beam. In an interview in June, Uttley said the prototype “H2 generation is up and running” and the H3 is under active development.
Honeywell’s Quantum Computing Unit Cambridge Quantum Computing, Its expertise is a matter of algorithms and other quantum software.
Ilyas Kahn, CEO of Cambridge Quantum Computing, who will take over the merged company, said in June that if regulatory hurdles were cleared and deals were closed, deeper collaboration would be possible and progress would be dramatic. He said it should accelerate.
Also on Wednesday, Honeywell and CQC announced a new quantum computing algorithm that solves optimization problems with fewer qubits.
