General quantum theory—unification of classical and modal quantum theories [PDF]
Journal of Physics A: Mathematical and Theoretical, 2020 Abstract Inspired by classical (‘actual’) quantum theory over C and modal quantum theory (MQT), which is a model

Quantum information theory and the foundations of quantum mechanics [PDF]
, 2004 This thesis is a contribution to the debate on the implications of quantum information theory for the foundational problems of quantum mechanics. In Part I an attempt is made to shed some light on the nature of information and quantum information theory.

npj Quantum Information, 2022 The problem of achieving security of device-independent (or semi-device-independent) cryptography (for quantum key distribution and randomness generation) against the most general no-signaling adversaries has remained open.

Bipartite nonlocality with a many-body system
New Journal of Physics, 2019 We consider a bipartite scenario where two parties hold ensembles of 1/2-spins which can only be measured collectively. We give numerical arguments supporting the conjecture that in this scenario no Bell inequality can be violated for arbitrary numbers ...

Unfree gauge symmetry in the BV formalism
European Physical Journal C: Particles and Fields, 2019 The BV formalism is proposed for the theories where the gauge symmetry parameters are unfree, being constrained by differential equations.

Taking Particle Physics Seriously: a Critique of the Algebraic Approach to Quantum Field Theory [PDF]
, 2011 I argue against the currently-prevalent view in philosophy of physics that algebraic quantum field theory (AQFT) is the correct framework for philosophy of quantum field theory and that "conventional" quantum field theory (CQFT), of the sort used in ...

Non-isometric codes for the black hole interior from fundamental and effective dynamics
Journal of High Energy Physics, 2023 We introduce a new holographic map for encoding black hole interiors by including both fundamental and effective dynamics. This holographic map is constructed by evolving a state in the effective, semiclassical gravity description of the interior ...

Quantum traces in quantum Teichmüller theory [PDF]
Algebraic & Geometric Topology, 2010 We prove that for the torus with a hole and the sphere with four holes there is a quantum trace function in the quantum Teichmuller space satisfying the properties proposed by Chekhov and Fock in "Observables in 3D Gravity and Geodesic Algebras".

How Quantum Theory Helps us Explain [PDF]
, 2012 I offer an account of how the quantum theory we have helps us explain the enormous variety of phenomena it is generally taken to explain. The account depends on what I have elsewhere called a pragmatist interpretation of the theory.
