Quantum conformal symmetries for spacetimes in superposition
Viktoria Kabel, Anne-Catherine de la Hamette, Esteban Castro-Ruiz +1
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical…
