  1. Undecidability and the problem of outcomes in quantum measurements.Rodolfo Gambini, Luis Pedro Garcia Pintos & Jorge Pullin - forthcoming - Foundations of Physics:93-115.
    We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...)

  • (1 other version)An axiomatic formulation of the Montevideo interpretation of quantum mechanics.Rodolfo Gambini, Luis Pedro García-Pintos & Jorge Pullin - 2011 - Studies in History and Philosophy of Science Part A 42 (4):256-263.
    We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of coherence due to the use of realistic clocks to measure time to solve the measurement problem. The resulting formulation is framed entirely in terms of quantum objects. Unlike in ordinary quantum mechanics, time only plays the role of an unobservable parameter. The formulation eliminates any privileged role of the measurement process giving an objective definition of when (...)

  • The montevideo interpretation of quantum mechanics: Frequently asked questions.Rodolfo Gambini & Jorge Pullin - 2009 - Journal of Physics Conference Series 174:012003.
    In a series of recent papers we have introduced a new interpretation of quantum mechanics, which for brevity we will call the Montevideo interpretation. In it, the quantum to classical transition is achieved via a phenomenon called “undecidability” which stems from environmental decoherence supplemented with a fundamental mechanism of loss of coherence due to gravity. Due to the fact that the interpretation grew from several results that are dispersed in the literature, we put together this straightforward-to-read article addressing some of (...)
