In recent years, Data driven decision making and scientific discovery has become essential for computing in areas such as finance and marketing, Internet of Things, telecommunications, climate, social, health-care, etc. While there have been some remarkable successes in the digital revolution, we might soon reach a point where the current computational tools will no longer be sufficient. There are many scientific challenges in Data Science ranging from data capture and storage to searching, modelling and visualization. The combination of quantum physics and information technology is a computational paradigm which has the potential to produce a new information processing device. Based on the laws of quantum mechanics, such a processing device seeks to carefully exploit quantum effects to resolve problems considered hard for classical machines.
