On the time-energy uncertainty relation
Speaker(s): Jos Uffink
Abstract: In contrast to Heisenberg's position-momentum uncertainty relation, the status of the time-energy uncertainty relation has always remained dubious, For example, it is often said that 'time' in quantum theory is not an observable and not represented by a self-adjoint operator. I will review the backg... read more

On the analogy between thermodynamics and quantum entanglement
Speaker(s): Jos Uffink
Abstract: According to the second law of thermodynamics the entropy of a system cannot decrease by adiabatic state transformations. In quantum mechanics, the 'degree of entanglement' of a state cannot increase under state transformations of a certain kind (local operations assisted by classical communication)... read more

Heisenberg's Uncertainty Principle
Speaker(s): Jos Uffink
Abstract: We will review the uncertainty principle of quantum mechanics, first formulated by Werner Heisenberg in 1927, and the role they played in the famous debate between Einstein and Bohr on the meaning of quantum theory. Along the way we will focus on questions like: what do we mean by "uncertainty", and... read more

Motivating outcome independence: locality versus sufficiency
Speaker(s): Jos Uffink
Abstract: It is well known that the derivation of the Bell Inequality rests on two major assumptions, usually called outcome independence and parameter independence. Parameter independence seems to have a straightforward motivation: it expresses a non-signalling requirement between space-like separated sites ... read more
