How will businesses use quantum technology in the future? What problems will a quantum computer solve? How long will it take before these devices become commercially relevant? With the first generation of quantum computers on the horizon, understanding their impact is more relevant than ever. Luckily, you don’t need a physics degree to understand the functionality of these computers – just like you don’t need to know how a transistor works to excel in conventional IT. This book is the perfect introduction to the opportunities and threats of quantum technologies. It equips you with the necessary knowledge to join cutting-edge discussions and make strategic decisions.
