't Hooft's quantum determinism: path integral viewpoint [PDF]
, 2005 We present a path integral formulation of ’t Hooft’s derivation of quantum from classical physics. Our approach is based on two concepts: Faddeev-Jackiw’s treatment of constrained systems and Gozzi’s path integral formulation of classical mechanics. This

QUANTUM DIAGONALIZATION METHOD IN THE TAVIS–CUMMINGS MODEL [PDF]
, 2004 To obtain the explicit form of evolution operator in the Tavis–Cummings model we must calculate the term e-itg(S+⊗a+S-⊗ a† explicitly which is very hard. In this paper we try to make the quantum matrix A ≡ S+ ⊗ a +S- ⊗ a† diagonal to calculate e-itgA and,

Reply to the Comment on ‘Quantum principle of relativity’ [PDF]
New Journal of Physics, 2023 We discuss critical remarks raised by Horodecki (2023 arXiv:2301.07802 [quant-ph]) toward our work on the connection between superluminal extension of special relativity and fundamental aspects of quantum theory.

Combinations of quantum observables and instruments [PDF]
Journal of Physics A: Mathematical and Theoretical, 2020 This article points out that observables and instruments can be combined in many ways that have natural and physical interpretations. We shall mainly concentrate on the mathematical properties of these combinations.

How to switch between relational quantum clocks [PDF]
New Journal of Physics, 2018 Every clock is a physical system and thereby ultimately quantum. A naturally arising question is thus how to describe time evolution relative to quantum clocks and, specifically, how the dynamics relative to different quantum clocks are related.

Quantum coordinates of an event in local quantum physics [PDF]
, 1998 Recently Toller [quant-ph/9702060 (1997)] has proposed, using the formalism of positive-operator-valued measures, a possible definition of quantum coordinates for events in the context of quantum mechanics.

Tunable negative permeability in a quantum plasmonic metamaterial [PDF]
, 2014 School of Chemistry and Physics, University of KwaZulu-Natal, Durban 4001, South Africa(Dated: January 22, 2014)We consider the integration of quantum emitters into a negative permeability metamaterial design in order tointroduce tunability as well as ...

Quantum control and the challenge of non-Hermitian model-building [PDF]
, 2015 In a way inspired by the brief 2002 note “The challenge of nonhermitian structures in physics” by Ramirez and Mielnik (with the text most easily available via arXiv:quant- ph/0211048) the situation in the theory is briefly summarized here as it looks ...

Measurement-based quantum computation beyond the one-way model [PDF]
, 2007 We introduce schemes for quantum computing based on local measurements on entangled resource states. This work elaborates on the framework established in Gross and Eisert [Phys. Rev. Lett. 98, 220503 (2007); quant-ph/0609149].
