I was interested in it in college probably 10 years ago. Took courses, learned about quantum circuits, bras and kets, bloch spheres (even wrote a 3D java applet to represent one). It seemed like it was going to be a revolution based on Quantum Computing. So compared to the excitement and the hype it hadn't quite happened.
Physics models of quantum phenomena are fantastic and interesting, but there can be a bit of lag between the theoretical developments underpinning the technology and the material science and general technological advances that make such theoretical developments real
anyway, quantum computing seems to be much closer than fusion, like few years away vs. 30. (personally though i'm betting on fusion as we have experimental verification of fusion where is quantum superposition is supposedly confirmed by Bell inequalities experiments and, not having the equipment myself, looking into papers on the experiments i see pretty big holes in them and thus "classical" interpretations of the results)
Yeah, I think one can check the status of quantum computing every 5-10 years, and still keep on being informed. The field has not taken any huge leaps.
