Quantum supremacy is no longer utopia! A new quantum computer has surpassed Google’s record, marking a turning point in the world of technology. While Google achieved a feat in 2019 with its quantum computer Sycamore, completing a task in 200 seconds that a classical supercomputer would have taken 10,000 years to complete, a new competitor called Quantinuum has just dethroned that giant.

Amazing take off
In January 2024, Quantum launched a series of experiments using quantum computer H2-1, equipped with 56 qubits. The result is amazing: Error correction performance is 100 times higher than Google. This progress is made possible by the algorithm Random circuit sampling It was documented in a study recently published on the arXiv preprint database.
Unprecedented performance
Quantinuum claims its system achieved a score of ~0.35 on the XEB (Xereo-Linear Entropy) benchmark, a 100x improvement over previous performance. This represents giant step Towards a fault-tolerant quantum computer, where logical qubits are more reliable than the physical qubits they are composed of.
A decisive step forward to correct the error
The error rates of logical circuits have been found to be up to 800 times lower than those of physical circuits, an achievement Quantinuum has not claimed by any other quantum computing company. Error correction is essential for long, complex calculations by protecting quantum information from noise and decoherence.
Historical importance of Google
Despite Quantinuum’s progress, Google’s achievement with Sycamore in 2019 remains historic. Google then demonstrated quantum supremacy, a major milestone in the development of quantum computing. This performance was disputed by IBM, which claimed that the task could have been completed in just 2.5 days by a conventional system.
Quantum vision
Ilyas Khan, founder and chief product officer of Quantinuum, acknowledges the importance of Google's achievement while emphasizing that his company's work bar raiseAccording to him, we are now in an era where traditional supercomputers cannot compete, and where the computational task is scalable and relevant.
The future of quantum technology
With this advance, Quantum is not only pushing the boundaries of technology; it is opening the way to practical applications that were once considered inaccessible to contemporary technology. Quantum computers could soon help solve problems that are still beyond the reach of current supercomputers.
The world's oldest computer is 2,000 years old, shocking historians and redefining our understanding of history
This article explores the emergence of Quantinuum as a new leader in quantum technology, surpassing Google’s previous achievements by an impressive margin. It examines advances in quantum error correction, laying the foundation for the future of large-scale computing, where quantum computers may one day outperform their classical counterparts in many areas.
