wait, but doesn't typical qm operate off of integrating over every possible quantum trajectory, including relativity-prohibited ones where particles take superluminal velocities? so if qtt is valid and otherwise compatible with vanilla qm, how does it address that discrepancy?
- ryanthedev 7y agoThe difference is the rate of the measurements and the data collected. Usually you would measure the results (average of sums). This is more like a Fourier transformation, where each movement is measured and the entire state is measured. Sum of averages.
- dangirsh 7y agoYou're confusing quantum trajectories for classical ones. The latter are what we use in path-integral formulations, and constitute a single path through spacetime. No such path exists for quantum states, since that would be a local hidden-variable theory (which has been experimentally ruled-out). Trajectories of quantum states are well described here: https://arxiv.org/abs/quant-ph/0302080 https://arxiv.org/abs/quant-ph/0302080
- miej 7y agoah right, thanks. been a few years since I did any qm work last
