Summoning, No-Signalling and Relativistic Bit Commitments
Entropy, 2019 Summoning is a task between two parties, Alice and Bob, with distributed networks of agents in space-time. Bob gives Alice a random quantum state, known to him but not her, at some point. She is required to return the state at some later point, belonging

Contextuality under weak assumptions
New Journal of Physics, 2017 The presence of contextuality in quantum theory was first highlighted by Bell, Kochen and Specker, who discovered that for quantum systems of three or more dimensions, measurements could not be viewed as deterministically revealing pre-existing ...

Observer-dependent locality of quantum events
New Journal of Physics, 2018 In general relativity, the causal structure between events is dynamical, but it is definite and observer-independent; events are point-like and the membership of an event A in the future or past light-cone of an event B is an observer-independent ...

Planck-Scale Soccer-Ball Problem: A Case of Mistaken Identity
Entropy, 2017 Over the last decade, it has been found that nonlinear laws of composition of momenta are predicted by some alternative approaches to “real” 4D quantum gravity, and by all formulations of dimensionally-reduced (3D) quantum gravity coupled to matter.

Local Scale Covariance and Its Radical Implications for Cosmology
Galaxies, 2021 Local scale covariance posits that no privileged length scales should appear in the fundamental equations of local, Minkowskian physics—why should nature have scale, but not position preferences?—yet, they clearly do.

Environment-Assisted Invariance Does Not Necessitate Born’s Rule for Quantum Measurement
Entropy, 2023 The argument of environment-assisted invariance (known as envariance) implying Born’s rule is widely used in models for quantum measurement to reason that they must yield the correct statistics, specifically for linear models.

Reverse Engineering Quantum Field Theory
, 2012 An approach to the foundations of quantum theory is advertised that proceeds by "reverse engineering" quantum field theory. As a concrete instance of this approach, the general boundary formulation of quantum theory is outlined.Comment: 5 pages, LaTeX ...

Quantum mechanics, strong emergence and ontological non-reducibility [PDF]
, 2015 We show that a new interpretation of quantum mechanics, in which the notion of event is defined without reference to measurement or observers, allows to construct a quantum general ontology based on systems, states and events.
