Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

Quantum Darwinism describes the proliferation, in the environment, of multiple records of
selected states of a quantum system. It explains how the quantum fragility of a state of a …

Over the course of the past decade, decoherence has become a ubiquitous scienti? c term
popular in all kinds of research, from fundamental theories of quantum physics to …

“How much information about a system S can one extract from a fragment F of the
environment E that decohered it?” is the central question of Quantum Darwinism. To date …

Core quantum postulates including the superposition principle and the unitarity of evolutions
are natural and strikingly simple. I show that—when supplemented with a limited version of …

The origin of classical reality in our quantum world is a long-standing mystery. Here, we
examine a nitrogen-vacancy center in diamond evolving in the presence of its magnetic …

Quantum Darwinism posits that only specific information about a quantum system that is
redundantly proliferated to many parts of its environment becomes accessible and objective …

Since Niels Bohr said this many years ago, quantum mechanics has only been getting more
shocking. We now realize that it's not really telling us that “weird” things happen out of sight …

We establish bounds on quantum correlations in many-body systems. They reveal what sort
of information about a quantum system can be simultaneously recorded in different parts of …

The emergence of the classical world from the quantum substrate of our Universe is a long-
standing conundrum. In this paper, I describe three insights into the transition from quantum …
