From Science Alert:
Some computations are so hardcore that it takes a facility of extraordinary power to even think about running them.
These are the supercomputers – massive facilities humming with the corpulence of their GPUs and CPUs, crunching applications that would take a desktop computer hundreds to thousands of years. A commercially accessible quantum computer has just accomplished a feat that suggests this newer technology could one day leave supercomputers in the dust. In just 19 seconds, IBM’s Nighthawk r2 processor generated a million samples – a task estimated to take a supercomputer around 110 years.
