In recent years, researchers question about the limits of the uncertainty relation.
Hints from quantum gravity theories suggest that the Heisenberg principle should be generalized.
Some considered implications in high energy physics, others have considered the mechanical motion of massive objects to look for possible tests of these supposed limits to the most important paradigm of quantum mechanics.
In a project funded by the John Templeton Foundation (grant number 58277), we consider the case of the photon, and study the possible way a generalized uncertainty principle may play a role in modern photonics, nonlinear and quantum optics.
The project started in 2015 and will finish in 2018, stay tuned.
