The hard version usually requires me to understand why a number, measurement or chemical or other substance doesn't make sense in the context of what each paragraph is describing. This means I can't just skim it in order to spot the fake, I need to figure out that what it's saying is wrong.

That's close enough for this to be a success if the purpose was to persuade or fool laymen.

This was a hard-mode fake I just got:

So some are better than others. :-)

I also got one that was a fake that was talking about measuring two actual quantum properties simultaneously by using a third state to probe it indirectly.

Which is absolutely a real thing except that the exact quantum properties in fact didn't commute while they claimed they did commute and said for some reason simultaneous measurement required a third state anyway.

I don't know how I would have been able to distinguish that from completely reasonable methods for quantum error correction without knowing ahead of time which quantum states commute and which don't... pretty cool.

If I were skimming or half asleep I definitely wouldn't have caught a lot of these on hard, abstracts are always so poorly written and usually trying too hard to be complicated sounding by using big words when small ones would do just fine!
