Delayed Choice Compatibly with Pilot Wave?

In summary, the new publication in Nature has demonstrated that if one chooses to believe that the atom really did take a particular path or paths then one has to accept that a future measurement is affecting the atom's past. Some people who understand Bohmian mechanics may not be surprised by this, but those with a superficial understanding of the theory may be puzzled.

With this new publication in Nature, http://www.nature.com/nphys/journal/v11/n7/full/nphys3343.html, they have proven that "if one chooses to believe that the atom really did take a particular path or paths then one has to accept that a future measurement is affecting the atom's past."

Do advocates of pilot wave/De-Broglie-Bohm now have to accept that current/future events affect past events?

Good question. My opinion: pilot wave theory have to morph into something more outlandish.

You can't prove anything in science. You can falsify or confirm some theory or hypothesis.
This particular experiment seems to falsify particle-wave duality idea. Particle-wave duality is outdated idea that comes from Bohr's earlier ideas (or maybe misunderstanding of Bohr's earlier ideas).

Particle-wave duality has nothing to do with pilot wave/De-Broglie-Bohm where both particle and a wave is there at all times.

There is an older thread about this experiment:

I cannot find the quoted sentence above at the link above.
Anyway, this quoted sentence, in the form in which it is written, is wrong. A correct version should be something like this:
If one chooses to believe that the atom really did take a particular path and that nothing else took both paths, then one has to accept that a future measurement is affecting the atom's past.
Note the added qualification "and that nothing else took both paths". This added qualification makes the statement (and the experiment) compatible with standard Bohmian mechanics. That's because in Bohmian mechanics it is not true that "that nothing else took both paths" (because there is a wave function that took both paths), so the conclusion of the statement does not refer to Bohmian mechanics. In other words, Bohmians do not need to accept that current/future events affect past events.

People with superficial understanding of Bohmian mechanics often forget that Bohmian mechanics is not only about particles. It is about particles and wave functions.

FAQ: Delayed Choice Compatibly with Pilot Wave?

1. What is Delayed Choice Compatibly with Pilot Wave?

Delayed Choice Compatibly with Pilot Wave is a theory in quantum mechanics that suggests that the behavior of particles can be influenced by future events, even after the particles have already been measured. It combines the concepts of delayed choice and pilot wave theory to explain the seemingly contradictory behavior of particles in quantum experiments.

2. How does Delayed Choice Compatibly with Pilot Wave work?

This theory proposes that particles have both wave-like and particle-like properties, and their behavior is determined by a pilot wave that guides their movement. The pilot wave is influenced by future events, and can therefore affect the behavior of particles even after they have been observed.

3. What are the implications of this theory?

If this theory is correct, it would challenge the traditional understanding of causality in quantum mechanics. It also suggests that the future can have an impact on the present, which goes against our everyday experience and intuition.

4. Has Delayed Choice Compatibly with Pilot Wave been proven?

There is ongoing debate and research surrounding this theory, and it is still a subject of much speculation and controversy. Some experiments have shown evidence that supports this theory, while others have not been able to replicate these results.

5. How does this theory compare to other interpretations of quantum mechanics?

Delayed Choice Compatibly with Pilot Wave is just one of many interpretations of quantum mechanics, and it is not widely accepted by the scientific community. Other interpretations, such as the Copenhagen interpretation and the many-worlds interpretation, offer different explanations for the behavior of particles in quantum experiments.
