[1] His work also addresses open questions in fundamental quantum mechanical concepts and historic experiments, such as mapping trajectories of photons passing though a double slit via weak measurement,[2] or timing particles tunnelling through a barrier.
[10] In 2011, Steinberg was awarded first place by Physics World in its yearly "top 10 breakthroughs" for his work leading "weak measurements" to "to track the average paths of single photons passing through a Young’s double-slit experiment".
[12] The researchers probed polarization states of the photons to verify that the weak measurements did not disturb the system at the magnitude the uncertainty principle would suggest.
[15] Another project exploiting properties of light was an experimental implementation of a method to resolve details beyond the Rayleigh Criterion with phase measurements.
[16] Steinberg has led work aiming to quantify how long a particle spends tunnelling through a barrier, confirming that the process is not instantaneous.
