Abstract

The role of time in relativistic quantum information science is attracting increasing interest. I will discuss two new results: entanglement between the future and the past; and progress towards a consistent quantum field theory for closed timelike curves.

Abstract

How does a quantum system evolve during measurement? The textbook picture of instantaneous, projective measurements only describes the situation before and after, but since any realistic experiment takes a finite amount of time, it is natural to talk about the evolution during the process. Surprisingly, using weak measurements it is possible to completely determine the evolution of the quantum state and look inside the so-called wavefunction collapse.
