Quantum Physics Postdoc here. Although technically correct this is also somewhat misleading. You need the band structure of solids, which is due to quantization and Pauli exclusion principle. The same quantum mechanics that explains why we did those strange electron energy levels for atoms in highschool. The majority of quantum mechanics, however, is not required: coherence, spin, entanglement, superposition. In the field we describe semiconductors as quantum 1.0, and devices that use entanglement and superposition (i.e. a quantum computer) as quantum 2.0, and smear everything else in-between. This
Oh my sweet summer child, a 100x yes, if only it were possible.
But more seriously, if you’re doing EE, the world of quantum is your oyster. Specialize in RF/MW design and implementation, we use it for qubit control, and you’ll be highly valuable.
Good question. It would be application specific. I think evanescencnt wave coupling in EM radiation is considered " very classical" (whatever that actually means). But utilizing wave particle duality for tunneling devices is past quantum 1.0 (1.5 maybe?). However, superconductivity tunneling in Josephson junctions in a SQUID is closer to quantum 1.0, but 2.0 if used to generate entangled states for superconducting qbits for quantum computing.

Can we trade?
Great write-up btw.

This what?
Oh no! The [clever quantum mechanics joke] got him!
[radioactive decay triggered the poison gas?]
[Quantum hype train?]
[Imposter syndrome?]
Interesting. Does tunneling fall under 1.0 or 2.0? Isn’t it considered a property of classical electrical engineering?

Clear as mud right?
It is now that I’ve looked up the different types of tunneling you mentioned. I didn’t know there were multiple types of tunneling before now.
Thanks for the informative reply and prompting me to do some reading!
