DESCRIPTION:Murat Kologlu\, Yale University\nWhat is the full set of obser
 vables in quantum gravity? I will introduce and discuss asymptotic detecto
 r operators and their measurements in perturbative quantum gravity in asym
 ptotically-flat spacetimes. The simplest example is an energy detector\, 
 which detects outgoing graviton radiation and records its energy. I will c
 onstruct large classes of general detector operators in QFT and in gravity
 \, defined as light-ray operators. I will present the first computation of
  an energy-energy correlator (EEC) as well as some of its generalizations 
 in perturbative quantum gravity. One can think of such observables as capt
 uring a universal part of quantum correlations between idealized LIGO dete
 ctors — as unlikely as it may be to be measured in the real world. Along
  the way\, I will comment on the "space of asymptotic detector operators" 
 in a gravitational theory.
