The meaning of redundancy and consensus in quantum objectivity [PDF]
Quantum, 2023 While the terms "redundancy" and "consensus" are often used as synonyms in the context of quantum objectivity, we show here that these should be understood as two related but distinct notions, that quantify different features of the quantum-to-classical ...

Quantum Darwinism in a Mixed Environment [PDF]
Physical Review Letters, 2009 Quantum Darwinism recognizes that we-the observers-acquire our information about the "systems of interest" indirectly from their imprints on the environment. Here, we show that information about a system can be acquired from a mixed-state, or hazy, environment, but the storage capacity of an environment fragment is suppressed by its initial entropy. In

Collisional unfolding of quantum Darwinism [PDF]
Physical Review A, 2019 We examine the emergence of objectivity via quantum Darwinism through the use of a collision model, i.e. where the dynamics is modeled through sequences of unitary interactions between the system and the individual constituents of the environment, termed "ancillas".

Quantum Darwinism in Quantum Brownian Motion [PDF]
Physical Review Letters, 2008 Quantum Darwinism--the redundant encoding of information about a decohering system in its environment--was proposed to reconcile the quantum nature of our Universe with apparent classicality. We report the first study of the dynamics of quantum Darwinism in a realistic model of decoherence, quantum Brownian motion.

Local Search and the Evolution of World Models
Topics in Cognitive Science, EarlyView., 2023 Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Anti-Zeno-based dynamical control of the unfolding of quantum Darwinism
Physical Review Research, 2020 We combine the collisional picture for open system dynamics and the control of the rate of decoherence provided by the quantum (anti-)Zeno effect to illustrate the temporal unfolding of the redundant encoding of information into a multipartite ...

Quantum security and theory of decoherence
New Journal of Physics, 2022 We sketch a relation between two crucial, yet independent, fields in quantum information research, viz. quantum decoherence and quantum cryptography. We investigate here how the standard cryptographic assumption of shielded laboratory, stating that data ...

Can Darwinism help us understand quantum mechanics? [PDF]
Belgrade Philosophical AnnualQuantum Mechanics is arguably the most controversial theory ever constructed: its overwhelming empirical success contrasts with the perplexity about its basic meaning.
