During the Age of Sailing, ships circumnavigated the Earth on journeys of discovery and trade. That era ended in the 1800s, when coal-fired steam engines began…

However, not all questions about quantum systems can be easily answered using quantum algorithms: some questions are equally easy with classical algorithms running on ordinary computers,…

We can decompose this diagonal motion into horizontal and vertical directions, but we will focus on the former here. The horizontal velocity (V1) and bounces off…
