From my understanding two particles' quantum states being entangled is what leads to the capacity to determine a property when the other entangled element is measured. I'm looking into exactly which properties of subatomic particles can be entangled. Can all properties of the particles be entangled.

$\begingroup$ Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. $\endgroup$– Community BotCommented Apr 28 at 17:00

1$\begingroup$ The question, as asked, is too broad to properly answer. There probably hundreds of various observables that have been demonstrated to show entanglement. Many are combined in experiments. It’s not really possible to provide a checklist. There is no specific restriction on entangled properties. Is there something more specific you are seeking? $\endgroup$– DrChineseCommented Apr 28 at 19:01

$\begingroup$ @DrChinese Hi I'm basically trying to understand if there are limitations to what properties of a subatomic particle can be entangled. $\endgroup$– Thomas MulierCommented Apr 28 at 20:27

$\begingroup$ Properties are not entangled. States are entangled. $\endgroup$– WillOCommented Apr 28 at 20:32

1$\begingroup$ Take any two particles with state spaces of more than one dimension. Take any observable for the first particle with (at least) two distinct eigenvalues, corresponding to eigenvectors U and V. Let E and F be any linearly independent states for the second particle. Then UE+DF is entangled in the sense you probably intend. $\endgroup$– WillOCommented Apr 28 at 20:37
