Towards Physics of Internal Observers: Exploring the Roles of External and Internal Observers
Marcin Nowakowski
In both quantum mechanics and relativity theory, the concept of the observer plays a critical role. However, there is no consensus on the definition of observer in these theories.…
Dynamical nonlocality in quantum time via modular operators
Ismael L. Paiva, Marcin Nowakowski, Eliahu Cohen
We formalize the concept of the modular energy operator within the Page and Wootters timeless framework. As a result, this operator is elevated to the same status as the more studi…
Consistency of quantum computation and the equivalence principle
Marcin Nowakowski
The equivalence principle, being one of the building blocks of general relativity, seems to be also crucial for analysis of quantum effects in gravity. In this paper we consider th…
Are temporal quantum correlations generally non-monogamous?
Marcin Nowakowski
In this paper we focus on the underlying quantum structure of temporal correlations and show their peculiar nature which differentiate them from spatial quantum correlations. We sh…
Classical dynamics from a unitary representation of the Galilei group
Andres D. Bermudez Manjarres, Marek Nowakowski, Davide Batic
We give a formulation of classical mechanics in the language of operators acting on a Hilbert space. The formulation given comes from a unitary irreducible representation of the Ga…
Entangled Histories vs. the Two-State-Vector Formalism - Towards a Better Understanding of Quantum Temporal Correlations
Marcin Nowakowski, Eliahu Cohen, Pawel Horodecki
The Two-State-Vector formalism and the Entangled Histories formalism are attempts to better understand quantum correlations in time. The main objective of this paper is to show tha…
Comment on "Measurements without probabilities in the final state proposal"
Eliahu Cohen, Marcin Nowakowski
The final state proposal [G.T. Horowitz and J.M. Maldacena, J. High Energy Phys. 2004(2), 8 (2004)] is an attempt to relax the apparent tension between string theory and semiclassi…
Quantum Entanglement in Time
Marcin Nowakowski
In this paper we present a concept of quantum entanglement in time in a context of entangled consistent histories. These considerations are supported by presentation of necessary t…
Monogamy of quantum entanglement in time
Marcin Nowakowski
In this paper we state a fundamental question about the structure of correlations in time and analyze temporal monogamy relations. We show that the nature of temporal correlations…
Symmetric extendibility of quantum states
Marcin L. Nowakowski
Studies on symmetric extendibility of quantum states become especially important in a context of analysis of one-way quantum measures of entanglement, distilabillity and security o…
Efficient bounds on quantum communication rates via their reduced variants
Marcin L. Nowakowski, Pawel Horodecki
We investigate one-way communication scenarios where Bob manipulating on his parts can transfer some sub-system to the environment. We define reduced versions of quantum communicat…
Simple test for quantum channel capacity
Pawel Horodecki, Marcin L. Nowakowski
Basing on states and channels isomorphism we point out that semidefinite programming can be used as a quick test for nonzero one-way quantum channel capacity. This can be achieved…
