Entanglement Decay of a proton pair

[sqljunkey]

Hi,

Suppose I had a pair of protons that are entangled, and one or both of those protons decayed( https://en.wikipedia.org/wiki/Proton_decay ) over time, does that mean the entanglement between the protons does not exist anymore, and would it be fair to say that the entanglement decayed over time?

First catch your entangled protons.
Hang them until ripe...

Slightly off-topic: Long, long ago, my 'Nuclear & Radio-Chemistry' lecturer admitted getting drunk to silence his nagging concerns about how/why neutrons decayed with ~14 min half-life, but protons didn't seem to decay at all...

IIRC, there are still some difficulties. Not least, why measuring free-neutron half-lives two ways gives results that differ by significantly more than those careful methods' error bars...

No, it means the entanglement between proton A and proton B, if proton B decays, turns into entanglement between proton A and whatever proton B decayed into.

would it be fair to say that the entanglement decayed over time?

No.
