Particles at the quantum level move in ‘surrealistic’ trajectories

Researchers have demonstrated through a new experiment that particles at quantum level behave much like billiard balls rolling along a table; however, they do not move in ‘realistic’ trajectories, but often move in a fashion termed ‘surrealistic’.

This sort of ties in with what I’ve been doing lately in quantum mechanics, perhaps. I’ve been looking at how to integrate the path integral in quantum mechanics in a way that avoids the direct use of probabilities (because the probability is a real number and I’m integrating in the complex plane).

> In 2011 CIFAR Senior Fellow Aephraim Steinberg (University of Toronto) and his colleagues were able to show that they could follow trajectories for photons by subjecting many identical particles to measurements so weak that the particles were barely disturbed, and then averaging out the information. This method showed trajectories that looked similar to classical ones – say, those of balls flying through the air.

So far so good.

>.both the standard interpretation of quantum mechanics and the De Broglie-Bohm (ie pilot wave) interpretation are consistent with experimental evidence, and are mathematically equivalent.

OK.
