Fundamental spatiotemporal decoherence: a key to solving the conceptual problems of black holes, cosmology and quantum mechanics
Rodolfo Gambini, Rafael Porto, Jorge Pullin
Unitarity is a pillar of quantum theory. Nevertheless, it is also a source of several of its conceptual problems. We note that in a world where measurements are relational, as is t…
Uniform discretizations: a new approach for the quantization of totally constrained systems
Miguel Campiglia, Cayetano Di Bartolo, Rodolfo Gambini +1
We discuss in detail the uniform discretization approach to the quantization of totally constrained theories. This approach allows to construct the continuum theory of interest as…
Relational physics with real rods and clocks and the measurement problem of quantum mechanics
Rodolfo Gambini, Jorge Pullin
The use of real clocks and measuring rods in quantum mechanics implies a natural loss of unitarity in the description of the theory. We briefly review this point and then discuss t…
Uniform discretizations: a quantization procedure for totally constrained systems including gravity
Miguel Campiglia, Cayetano Di Bartolo, Rodolfo Gambini +1
We present a new method for the quantization of totally constrained systems including general relativity. The method consists in constructing discretized theories that have a well…
Fundamental decoherence from quantum gravity: a pedagogical review
Rodolfo Gambini, Rafael Porto, Jorge Pullin
We present a discussion of the fundamental loss of unitarity that appears in quantum mechanics due to the use of a physical apparatus to measure time. This induces a decoherence ef…
