A new quantum computer breaks Google's quantum supremacy record by 100-fold
A new 56-qubit H2-1 computer has dislodged Google's Sycamore quantum computer from its 'quantum supremacy' record by 100-fold.
Last month, a company called Quantinuum said it reached an error correction performance threshold that many believed was years away. Google's Sycamore quantum computer features 53 qubits and was first introduced in 2019 when it completed a specific task in 200 seconds, registerin g an XEB result of approximately 0.002. "When, in late 2019, Google released details of their 'quantum supremacy' experiment, Sundar Pichai their CEO published a blog that has withstood the test of time with respect to the importance of the milestone that was then reached," he said.
