There is an often-repeated statement that different quantum mechanical theories are equivalent. This is an over-simplification. Is wave function collapse is a real thing or just an approximation of what happens when a large system is entangled?
Some smart people have tried to make theories where wave function collapse is a real thing. These new experiments are working to rule out those ideas.
My feeling is that Everett's "many worlds" interpretation is the clear favorite: there is no wave function collapse.
