## Description

Quantum Computing is rapidly moving from theoretical possibility to reality, and is likely to soon majorly affect software development and society. Ignoring it is no longer a sensible option.

In this talk, we’ll explain the basics of quantum mechanics, and how its core principles - superposition, entanglement, and quantum gates - are leveraged by quantum computers. We’ll see which complex problems (like simulation, optimization, and potentially disrupting cybersecurity) they are uniquely suited to solve, because they aren't a magic bullet for every task.

How are big tech players and startups investing in the space? What real-world applications already exist, when will it hit the mainstream, and does China really do quantum encryption in space? Lastly, how can we prepare for a quantum-enabled future?
