SUMMARY
The recent experiment conducted by researchers at the University of Toronto successfully mapped the trajectories of single photons in a double-slit interferometer using weak measurements. This approach allows for the simultaneous observation of both the particle and wave nature of light, challenging traditional interpretations of quantum mechanics, particularly the many-worlds interpretation. However, the results do not provide definitive information about the path of individual photons, reinforcing the notion that quantum particles do not have well-defined trajectories. The findings align with standard quantum mechanics and suggest that Bohmian trajectories may not be hidden variables but integral to quantum mechanics itself.
