have fallen victim to a fraudulent transaction . Algorithms used in the payment card industry mean this is , fortunately , a rare occurrence . But , as Richard Hopkins – Distinguished Engineer at IBM and Fellow of the Royal Academy of Engineering – explained to Technology Magazine earlier this year , even small improvements to those algorithms will have a sizable impact , with evidence already demonstrating that quantum computers can help to resolve these common problems .
“ We ’ ve recently published a paper where we took information about real debit and credit card details and transactions , and passed them through a quantum algorithm and two conventional algorithms ,” Hopkins says .
“ Even with today ’ s quantum hardware , provided we let the quantum computer select the parameters to predict the fraud , then we would get the same level of accuracy out of an intermediate-scale quantum computer ,” he explains . “ That , in itself , is not bad going , but it doesn ’ t get you to that quantum advantage .”
However , as Hopkins describes , the quantum algorithm was able to make qualitatively different judgements and , as a result , come to different conclusions .
