Google says it's quantum processor, Sycamore, performed a truly random-number generation in 200 seconds and that same task would take about 10,000 years for a state-of-the-art supercomputer to execute. IBM has pushed back, saying Google hasn't achieved supremacy because "ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity." It sounds like the quantum supremacy war is heating up. On the patent front, IBM had five new patents and two publications in the past two weeks, whereas Google only had two publications.
