Conventional Quantum Theory Does Not Support a Coherent Relational Account
Philosophy of PhysicsQuantum theory in its conventional formulation is notoriously subject to various measurement-related paradoxes, as exemplified by the “Schrödinger’s Cat” and “Wigner’s Friend” thought experiments. It has been shown, for example, by Frauchiger and Renner,

On the Relation Between Quantum Computational Speedup and Retrocausality
Quanta, 2016 We investigate the reason for the quantum speedup (quantum algorithms require fewer computation steps than their classical counterparts). We extend the representation of the quantum algorithm to the process of setting the problem, namely choosing the ...

Minimal areas from entangled matrices
SciPost PhysicsWe define a relational notion of a subsystem in theories of matrix quantum mechanics and show how the corresponding entanglement entropy can be given as a minimisation, exhibiting many similarities to the Ryu-Takayanagi formula.

Rovelli’s Relational Quantum Mechanics, Anti-Monism, and Quantum Becoming [PDF]
, 2016 In the first section I present in some details Rovelli’s RMQ. In the second I defend it from some foreseeable objections, so as to clarify its philosophical implications vis à vis some rival but closely related interpretations. In particular I ask whether RQM presupposes a hidden recourse to a duality of both temporal evolutions and ontology (the ...

A link between static and dynamical perturbation theory
New Journal of PhysicsDynamics, the physical change in time and a pillar of natural sciences, can be regarded as an emergent phenomenon when the system of interest is part of a larger, static one.

Structural Entanglement from Interaction-Induced Fixed Points
EntropyWe introduce a lattice-theoretic framework for composite information systems in which tensor-like composition and entanglement are defined without presupposing Hilbert spaces or quantum states.

An analysis of relational quantum mechanics
, 2023 In this thesis, I argue that no current version of Relational Quantum Mechanics (RQM) both meets its own goals and solves the problem of measurement, and the prospects that any such interpretation could be articulated are not promising. I offer a clear illustration of the core framework of RQM and I note that all versions of RQM share an ontology of ...

Beyond symbolic algebra with quantum picturalism
Frontiers in CognitionThe more advanced the symbolic mathematics, the more impenetrable the meaning. This is particularly evident in quantum theory, where symbolic formalisms foreground states and objects.

Representation and Perspective in Science
Principia: An International Journal of Epistemology, 2007 The world science describes tends to have a very strange look. We can’t see atoms or force fields, nor are they imaginable within visualizable categories, so neither can we even imagine what the world must be like according to recent physical theories ...
