Quantum Computing @ Grace Hopper Conference 2019 GHC19

I had recently attended the Grace Hopper 2019 conference in Orlando, and had the opportunity to speak with researchers from IBMQ and Qiskit about the current state of quantum computing. Although, I did not get a chance to obtain a ticket to IBMQ's Universal Studios event at The Wizarding World of Harry Potter (the line was extremely long!), I still wanted to share some of the topics surrounding the emerging tech of quantum computing.

I spoke with Cihan Kurter, Research Scientist at IBM Watson, after her presentation titled, "Near-Term Applications of Quantum Computers", and asked, how exactly does the mysterious IBMQ qubit work?

How does a qubit work?

Gary is an avid hiker. He tracks his hikes meticulously, paying close attention to small details like topography. During his last hike he took exactly steps. For every step he took, he noted if it was an uphill, , or a downhill, step. Gary's hikes start and end at sea level and each step up or down represents a unit change in altitude. We define the following terms:

A mountain is a sequence of consecutive steps above sea level, starting with a step up from sea level and ending with a step down to sea level. A valley is a sequence of consecutive steps below sea level, starting with a step down from sea level and ending with a step up to sea level. Given Gary's sequence of up and down steps during his last hike, find and print the number of valleys he walked through.

For example, if Gary's path is DDUUUUDD, he first enters a valley 2 units deep. Then he climbs out an up onto a mountain 2 units high. Finally, he returns to sea level and ends his hike.
