> In an influential [2008] paper, Noah Linden, Sandu Popescu, Tony Short and Andreas Winter argued that the arrow of time can be explained in terms of quantum mechanical entanglement. As a physical system becomes entangled with its surroundings, it moves closer to equilibrium — and this one-way evolution determines time’s arrow.

There is an alternative, much simpler way of looking at it that dates back to an overlooked 1996 paper by Nicolas Cerf and Christof Adami: the arrow of time depends on entanglement because that's the only way to get classical correlations (i.e. memories) out of quantum mechanics.

You can arrive at the same conclusion relying solely on the theory of decoherence, which can be traced back as early as 1970:

This is way off-topic, but...

I remember reading once the idea that cats can remember the future.

But I am unable to re-locate the source of this idea. Can anyone help ?

You might be thinking about about done cats and dogs can tell an earthquake is coming a minute or two before it hits. That's not as much remembering the future as it likely is having a sense that we don't. But, it can feel like it

Instead of a sense we don't, it's probably just picking up on the P-waves instead of first noticing with the S-waves: https://earthquake.usgs.gov/earthquakes/events/1906calif/18a...

Uh, that won't be discovered until 2057.

You aren't by any chance a cat, are you?

closest I know of is the short story: F Lieber, "Space-Time for Springers" (1958)

No, because it's BS.
