  • 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







  • I’m not going back arch/bazzite to try this. For two reasons, 1. I can’t enable those things, my hardware doesn’t support reBAR. And 2. My issue sounds potentially different. I could load and run the game, but it would crash regularly. Realistically, if this is the issue my only solution is to roll back to an old kernel (not supported in arch), and I’m not sure if that fly’s in bazzite either. Distro hoping to Mint is then a great solution, even if I didn’t take a rational path there.



  • Oh yeh good catch.

    I can’t do resizable bar, so it would have been a kernel regression to fix (if that was the issue). I think patched in next release. Although I never got any error messaging in any logs that i could see :(

    The nice thing about the deck, at least from an outsiders perspective, is that everyone’s got the more or less same hardware. If you have an issue most likely someone else has the same issue, and already has a fix that’ll work for you.
