Reconstructing quantum theory from diagrammatic postulates [PDF]
Quantum, 2018 A reconstruction of quantum theory refers to both a mathematical and a conceptual paradigm that allows one to derive the usual formulation of quantum theory from a set of primitive assumptions.

Higher-order interference in extensions of quantum theory [PDF]
, 2016 Quantum interference lies at the heart of several quantum computational speed-ups and provides a striking example of a phenomenon with no classical counterpart. An intriguing feature of quantum interference arises in a three slit experiment.

International Journal of Modern Physics A, 2005 The scope of this review is to give a pedagogical introduction to some new calculations and methods developed by the author in the context of quantum groups and their applications. The review is self-contained and serves as a "first aid kit" before one ventures into the beautiful but bewildering landscape of Woronowicz's theory.

Quantum Trajectories and Quantum Measurement Theory [PDF]
, 2003 Beyond their use as numerical tools, quantum trajectories can be ascribed a degree of reality in terms of quantum measurement theory. In fact, they arise naturally from considering continuous observation of a damped quantum system.

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.

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 ...

Introduction to quantum groups [PDF]
, 1997 We give an elementary introduction to the theory of algebraic and topological quantum groups (in the spirit of S. L. Woronowicz). In particular, we recall the basic facts from Hopf (*-) algebra theory, theory of compact (matrix) quantum groups and the ...

Discrete quantum theories [PDF]
Journal of Physics A: Mathematical and Theoretical, 2014 We explore finite-field frameworks for quantum theory and quantum computation. The simplest theory, defined over unrestricted finite fields, is unnaturally strong. A second framework employs only finite fields with no solution to x^2+1=0, and thus permits an elegant complex representation of the extended field by adjoining i=\sqrt{-1}. Quantum theories
