Is it possible for an entangled system of particles to be disentangled at a distance, without making them interact directly with each other?
 
Physics news on Phys.org
Yes, by measuring one or both.
 
ok, fine, but they will still be entangled once you stop making a measurment right?

No. The interaction necessary to make a measurement breaks the entanglement.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
