Abstract:  One of the cornerstones of Quantum Mechanics (QM), Heisenberg'sUncertainty Principle (HUP), establishes that it is not possibleto simultaneously measure with arbitrary precision both theposition and the momentum of a quantum system. This principle,however, does not prevent one from measuring with infiniteprecision the system's position. However, theories of QuantumGravity, aiming to bridge between General Relativity and QM,predict the existence of a minimal observable length - a minimaluncertainty on the position generally of the order of the Plancklength. This prediction results therefore in a contradiction withHUP, requiring a modification of the principle. This need gaverise to the Generalized Uncertainty Principle (GUP). In this talk,I will show how the GUP can change known aspects of standard QM,leading to ways to test Quantum Gravity.
