Quantinuum Injects Topology Into Ion-Chain Quantum Entanglement to Solve Quantum Computing Error Correction
Quantinuum, a trapped ion specialist quantum computing company formed by merging Honeywell’s quantum computing unit and a Cambridge-based quantum start-up, says it is “a reliable path to fault-tolerant quantum computing.” It claims to have unleashed what it calls (opens in new tab)The statement, which overshadows other fault-tolerance pursuits and promises a smoother path to the quantum future, is backed up by the company’s latest research on quantum systems.
Published yesterday in preprint formthis study describes a new approach that links the Italian aristocratic Borromeo family and its coat of arms to the “distant and macabre behavior” of quantum entanglement.
The Borromean rings in the Borromean coat of arms are an interesting visual representation of quantum entanglement. A strange phenomenon in which groups of particles remain linked in such a way that they are all part of the same system, despite having no physical component at all. connection or proximity. And just like in quantum systems, removing one of the rings means removing the connection between them all. This corresponds to the phenomenon of quantum decoherence.
Quantinuum’s work focused on trying to connect entangled qubits based on non-Abelian anyons (non-Abellion is its shortened version). Proximity of particles (helps increase coherence time) while adding resilience to events that trigger decoherence. Overall, the team demonstrated quantum entanglement across 32 ion-based qubits.
Ashvin Vishwanath, a theoretical physicist at Harvard University in Cambridge, Massachusetts, and co-author of the paper, said: “It’s a really amazing state of matter, and it’s not very clearly perceived in other setups.”
It’s important to note both proponents and critics of new research, especially regarding quantum computing, the ChatGPT-level hype machine.
Comments on the paper published by Quantinuum NatureStephen Simon, a theoretical physicist at the University of Oxford, England, said, “There is immense mathematical beauty in physical systems of this type, and it is incredible to see them realized for the first time after so long.” No,’ he said.
Michael Manfra, an experimental physicist at Purdue University in West Lafayette, said: Nature The Quantinum Machine did not truly create Non-Abellion. Rather, we simulated their properties (and only some of them). Quantinuum agrees, but the particles behave to meet the definition of nonabelion, and he also argues that the checkmark for a tolerant quantum computing system is there.
So while “trusted trails” may need to be explored a bit more, it’s clear that the Quantinuum result is an achievement in itself.
Interestingly, Quantinuum’s research and claims of a path found for scaling true quantum computing collide with Microsoft’s. The company is also pursuing topological qubits in quantum computing research that treats quantum systems differently than Quantinuum’s early ion-chain qubits and IBM’s superconductivity. For example qubits.
However, while Quantinuum’s approach simulates the topological behavior of non-abelian qubits to exploit the “Borromian ring” effect for robustness, Microsoft is pursuing qubits composed of physical anyions themselves. increase.
Overall, there are still doubts as to whether “a credible path to fault-tolerant quantum computing” has been unleashed in yesterday’s preprint publication. But we have taken a step forward. Quantinuum is now trying to find out exactly where it ends.
