Quantum
The University of Delft has a great introduction to Quantum Computing at Qutech Academy. (Buckle up if you want to follow, get your linear algebra skills dusted of and some physics.) Quantum computing is slowly becoming a reality. Today, It is somewhere between research and reality. Like the state of classical computing in the 1950s / 1960s, the difference is that today, we are better able to assess the potential of such technology than we could imagine what computing would mean in the 1950s.
And it will be big. It’s more impactful and real than the current AI hype.
I dug into the Qutech Academy after attending the Qiskit Summer School by IBM, which was somewhat over my head. But it’s an extremely interesting space well worth digging into.
