  • Cold turkey worked for me. Took me 4 attempts. I wasn’t hard on myself for failure, I noted what happened (emotional trauma, stress, alcohol) and prepared myself for the next attempt.

    I wanted to quit, so when I relapsed it’s not because I wanted to smoke but because those little cancer stick bastards were trying hardest to kill me. But if they were going to be tough, I could be tougher. I found it easier when I could see the cigs as my enemy.


  • 10 years ago I learnt that southern New Zealand slang uses bespoke or custom as an indicator of poor quality. Someone shittly welded a tow ball onto their car, that’s a ‘custom job’.

    Your poorly assembled second hand IKEA bookshelf that’s falling apart and well fucked? A bespoke piece of furniture.

    Those words have never bothered me since. Thanks kiwis.






  • No, I am not sure that I am.

    Photonic processing, whilst very cool and super exciting, is not a quantum thing… Maxwells equations are exceedingly classical.

    As for the rest it’s transistor design optimisation, enabled predominantly by materials science and ASMLs EUV tech I guess:), but still exploits the same underlying ‘quantum 1.0’ physics.

    Spintronics (which could be what you mean by 2D) is for sure in-between (1.5?), leveraging spin for low energy compute.

    Quantum 2.0 is systems exploiting entanglement and superposition - i.e. qubits in a QPU (and a few quantum sensing applications).



  • 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.

    Clear as mud right?



  • 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
