Quantinuum announced yesterday that the number of fully connected qubits of its flagship product, the System Model H2 quantum computer, has increased from 32 to 56. It also released a research result achieved through collaboration with partners including JPMorgan Chase. They used the H2-1 quantum processor to solve the problem of random circuit sampling and measured the quality of their results through a suite of benchmark tests. They found that the system scored approximately 0.35 on the linear cross-entropy benchmark (XEB) test, while the XEB score of the system that Google previously used to achieve quantum supremacy was about 0.002.
