Google scientists set the computing world abuzz in October 2019 by announcing its quantum computer had solved a problem in just 200 sec that a classical computer would take years—10000 by Googles estimation—to solve [1]. The achievement, since disputed by scientists at the Intational Business Machines Corporation (IBM) and downplayed by many experts in the field as too esoteric, signaled proof to Google investigators that quantum computers can achieve quantum supremacy and overwhelm-ingly outperform even the worlds most powerful classical comput-ers on certain tasks. In the future, more robust, powerful versions of quantum computers like Googles, which exploit the properties of matter at subatomic scales to significantly improve processing power, could revolutionize computing, encrypting data, and inves-tigating some of the most mysterious aspects of nature.
