AMHERST, Mass.—A computer science professor at Amherst College who recently devised and conducted experiments to test the speed of a quantum computing system against conventional computing methods will soon be presenting a paper with her verdict: quantum computing is, “in some cases, really, really fast.”
“Ours is the first paper to my knowledge that compares the quantum approach to conventional methods using the same set of problems,” says Catherine McGeoch, the Beitzel Professor in Technology and Society (Computer Science) at Amherst. “I’m not claiming that this is the last word, but it’s a first word, a start in trying to sort out what it can do and can’t do.”
The quantum computer system she was testing, produced by D-Wave just outside Vancouver, BC, has a thumbnail-sized chip that is stored in a dilution refrigerator within a shielded cabinet at near absolute zero, or .02 degrees Kelvin in order to perform its calculations. Whereas conventional computing is binary, 1s and 0s get mashed up in quantum computing, and within that super-cooled (and non-observable) state of flux, a lightning-quick logic takes place, capable of solving problems thousands of times faster than conventional computing methods can, according to her findings.
