Quantum computing is one of the current big things in both physics and computer science circles. But there is a serious divide between what we think might be possible and what we can, in fact, do.

Waveguide has many practical uses in high-powered RF systems, as covered in the last tutorial. Specifically, it is used as a transmission line for higher frequencies ranging from the UHF band up ...
