Comment on ‘Single particle nonlocality with completely independent reference states’

open access: yesNew Journal of Physics, 2022
We comment on the purported violation of local realism, by a single photon induced correlations between homodyne detectors, which one can find in: (2008) New J. Phys. 10 113024 [arXiv: 0807.0109 ].

On quantum theory [PDF]

open access: yesThe European Physical Journal D, 2013
Quantum theory is a well-defined local theory with a clear interpretation. No "measurement problem" or any other foundational matters are waiting to be settled.

Single trusted qubit is necessary and sufficient for quantum realization of extremal no-signaling correlations

open access: yesnpj 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.

Holographic quantum states [PDF]

open access: yes, 2010
We show how continuous matrix product states of quantum field theories can be described in terms of the dissipative non-equilibrium dynamics of a lower-dimensional auxiliary boundary field theory.

QUANTUM FIELD THEORIES [PDF]

open access: yesInternational 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.

Discrete quantum theories [PDF]

open access: yesJournal 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

Bipartite nonlocality with a many-body system

open access: yesNew 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

open access: yesEuropean 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.

Introduction to quantum groups [PDF]

open access: yes, 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 ...
