Quantum Property: Can a Particle Have It Both Ways?

[Einstein's Cat]

Can a particle have both a quantum property and not have that same quantum property?

 

[Nugatory]

Can a particle have both a quantum property and not have that same quantum property?

If you measure the property, you'll get a value.
If you don't measure it, you won't.

From this, you can draw any conclusions you want about whether the particle (strictly speaking, the quantum system) has that property or not.
