A new quantum computer has achieved a groundbreaking feat by breaking the 'quantum supremacy' record set by Google's Sycamore machine. The 56-qubit H2-1 quantum computer, developed by the company Quantinuum, outperformed the previous benchmark by a factor of 100. This means that it can produce results without errors 35% of the time, as measured by the XMB score. Additionally, the H2-1 quantum computer consumes 30,000 times less power
