Microsoft may have finally made quantum computing useful

The dream of quantum computing has always been an interesting one: What if we could create a machine that works at the quantum level that can handle the most complex calculations faster than the smallest computer and classical physics? But even he saw IBM, Google and others announcing iterative quantum computing hardwarethey it is not used for any purpose. It can change and announced today from Microsoft and Quantinuumwho claim to have created the most flawless computer system to date.

While classical and electronic computers rely on binary bits as their unit of information (they can be on or off), quantum computers work with qubits, which can be in two states at once. The problem with qubits is that they can make mistakes, which is the main reason for today’s (so-called Noisy Intermediate Scale Quantum) computers. [NISQ] computers) are only used for research and testing purposes.

Microsoft’s solution was to split the physical qubits into virtual qubits, which allow them to use error detection and control without destroying them, and run on all Quantinuum devices. The result was an error that was 800 times greater than relying on physical qubits alone. Microsoft says it managed to run more than 14,000 tests without any errors.

According to Jason Zander, EVP of Microsoft’s Strategic Missions and Technologies division, this achievement could lead us to “Level 2 Resilient” quantum computing, which would be reliable for use.

“Current work in quantum computing is increasing the fidelity of qubits and enabling fault-tolerant computing so that we can use quantum mechanics to unlock solutions to previously unsolvable problems,” Zander wrote in a post today. “In short, we need to switch to reliable devices – made by combining several physical qubits together in a logical way to protect against noise and keep a long time (ie, stable). … the ability to use errors built into the machine, we can get better results than any single part can give us .”

Microsoft Quantum Computing


Researchers will be able to get a taste of Microsoft’s supercomputer through Azure Quantum Elements in the coming months, where it will be available as a private preview. The goal is to push to Level 3 quantum supercomputing, which in theory will be able to solve complex problems such as climate change and exotic medicine research. It’s unclear how long it will take to get there, but for now, we’re moving one step closer to quantum computing.
