This development represents a crucial step in the evolution of quantum computing.
A new era for quantum computing
Quantinuum has reached a milestone with its H2-1 quantum computer, which outperforms existing machines. With 56 qubits, the device demonstrates unprecedented computing power. The quantum bits allow the computer to perform complex calculations in seconds, a task that would take a typical supercomputer thousands of years.

The results of their experiments, published June 4 on arXiv, show that H2-1 produces error-free results at a record level. However, these results have not yet been evaluated by experts, leaving a margin of uncertainty about their ultimate validity.
The Race for Quantum Supremacy
Quantum supremacy is an ambitious goal that requires quantum computers with millions of qubits. Currently, the largest machines have about 1,000 qubits, and Quantinuum is focusing on the reliability of its qubits rather than their number, a strategic choice to improve overall performance.

The XEB benchmark used to test H2-1 revealed a score of 0.35, much higher than the 0.002 achieved by Google’s Sycamore computer in 2019. This result means that H2-1 can produce error-free results 35% of the time, a major advance in the field.
Implications for the future
“Our goal is to develop universal and reliable quantum computers,” said Ilyas Khan, product manager at Quantinuum. “The results obtained by H2-1 indicate that these benefits can be achieved sooner than expected, paving the way for major innovations.”
The app that suggests the right meal
Quantum computers could revolutionize many fields, from cryptography to simulating complex molecules in medicine. The increased reliability of quantum bits is an important step toward these practical applications.
