On the connection between the categorical and the modal logic approaches to Quantum Mechanics
Quantum Mechanics Category Theory Modal Logic
2016/6/12
This thesis aims at connecting the two research programs known as Categorical Quantum Mechanics and Dynamic Quantum Logic. This is achieved in three steps. First we define a procedure to extract a Mod...
On the Necessity of Entanglement for the Explanation of Quantum Speedup
quantum computation quantum speedup quantum information entanglement DQC1 mixed state explanation
2016/6/12
Of the many and varied applications of quantum information theory, perhaps the most fascinating is the sub-field of quantum computation. In this sub-field, computational algorithms are designed which ...
On the Debate Concerning the Proper Characterisation of Quantum Dynamical Evolution
open quantum systems quantum dynamics dynamical maps assignment maps not completely positive maps
2016/6/12
There has been a long-standing and sometimes passionate debate between physicists over whether a dynamical framework for quantum systems should incorporate not completely positive (NCP) maps in additi...
The Everett Interpretation of Quantum Mechanics.Collected Works 1955-1980 with Commentary.Hugh Everett III,edited by Jeffrey A.Barrett & Peter Byrne.Princeton:Princeton University Press (xii+389 pp.)
Everett quantum mechanics
2016/6/12
This is a review of Barrett and Byrne's commented edition of Everett's collected works, originally published in HOPOS 3 (2013), 348-352, but here including footnotes and references (omitted from the o...
Pragmatists and Purists on CPT Invariance in Relativistic Quantum Field Theories
quantum field theory CPT theorem causal perturbation theory
2016/6/12
Philosophers of physics are split on whether foundational issues in relativistic quantum field theory (RQFT) should be framed within pragmatist approaches, which trade mathematical rigor for the abili...
Some Observations upon “Realistic” Trajectories in Bohmian Quantum Mechanics
quantum mechanics Bohmian quantum mechanics realistic trajectory quantum position mecanica cuantica interpretacion de Bohm trayectoria bohmiana trayectoria realista posicion
2016/6/12
Experimental situations in which we observe quantum effects that deviate from the intuitive expectations of the classical world call for an interdisciplinary discussion, and one fundamental issue to b...
The Oxford Questions on the foundations of quantum physics

2016/6/12
The twentieth century saw two fundamental revolutions in physics—relativity and quantum. Daily use of these theories can numb the sense of wonder at their immense empirical success. Does their instrum...
Assessing the Montevideo Interpretation of Quantum Mechanics
Montevideo interpretation quantum clocks decoherence Everett interpretation
2016/6/12
This paper gives a philosophical assessment of the Montevideo interpretation of quantum theory, advocated by Gambini, Pullin and co-authors. This interpretation has the merit of linking its proposal a...
Topos-Theoretic Approaches to Quantum Theory
Topos theory quantum logic category theory operational quantum mechanics
2016/5/31
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is ...
Recent years have seen a good deal of work done on one of the most mind blowing and conceptually radical views in quantum mechanics, namely the ‘many worlds’ interpretation of quantum mechanics. Many ...
I argue that the fundamental space of a quantum mechanical world is the wavefunction's space. I argue for this using some very general principles that guide our inferences to the fundamental nature of...
Quantum Objects
Measurement problem interpretation of quantum mechanics four-dimensionalism unsharp reality Sadra Philosophy
2016/5/30
In this paper, we suggest an alternative interpretation for the quantum state vector, which, by considering temporal parts for physical objects, aims to give an intelligible account of measurement pro...
A dilemma for the emergence of spacetime in canonical quantum gravity
spacetime emergence quantum geometrodynamics loop quantum gravity quantum superposition quantum entanglement non-separability structural realism local beables
2016/5/30
The procedures of canonical quantization of the gravitational field apparently lead to entities for which any interpretation in terms of spatio-temporal localization or spatio-temporal extension seems...
Realism and objectivism in quantum mechanics
classical physical ontology quantum entanglement nonseparability contextuality quantum object objectivity realism
2016/5/30
The present study attempts to provide a consistent and coherent account of what the world could be like, given the conceptual framework and results of contemporary quantum theory. It is suggested that...
Individuality,quantum physics,and a metaphysics of non-individuals:the role of the formal
non-individuals individuality quantum objects identity
2016/5/30
The notion of an individual and the related issues on individuation are topics that appear in the philosophical discussion ever since the antiquity. The idea of an individual thing is intuitively clea...
