Hurling ordure at the TREACLES, especially those closely related to LessWrong.

AI-Industrial-Complex grift is fine as long as it sufficiently relates to the AI doom from the TREACLES. (Though TechTakes may be more suitable.)

This is sneer club, not debate club. Unless it's amusing debate.

[Especially don't debate the race scientists, if any sneak in - we ban and delete them as unsuitable for the server.]

If you really want to cite someone he admires, you could note that Eliezer Yudkowsky uses 1 as a probability when trying (and failing) to explain quantum mechanics, because he writes probability amplitudes of absolute value 1.

I’m glad I’ve never pissed off a career physicist, cause this is concise, targeted destruction

If you want more of this, I wrote a full critique of his mangled intro to quantum physics, where he forgets the whole "conservation of energy" thing.

Thanks for taking on that task (I linked to your post to provide further details).

fuck yes. I can tell already this’ll need more brain than I can give it during work, but from the first few paragraphs this seems like absolutely my kind of shit

despite phase shifts being the main cause of the described effects.

what are the other ones?

(when i'm thinking about splitter with pi/2 phase shift, i'm thinking about coupled line coupler or its waveguide analogue, but i come from microwave land on this one. maybe this works in fibers?)

I guess the rest of the experimental setup that recombines the photon amplitiudes. Like if you put 5 extra beam splitters in the bottom path, there wouldn't be full destructive interference.

when i’m thinking about splitter with pi/4 phase shift, i’m thinking about coupled line coupler or its waveguide analogue, but i come from microwave land on this one. maybe this works in fibers?

I'm not sure how you'd actually build a symmetric beam splitter: wikipedia said you'd need to induce a particular extra phase shift on both transmission and reflection. (I'm fully theoretical physics so I'm not too familiar).

pi/2, sorry

In microwave land we have something called rat race coupler which can be used as an in-phase 1:1 splitter. This thing can be manufactured in waveguides so maybe (narrowband) fiber optic implementation is possible
