### Quantifying Decoherence via Increases in Classicality

- Computer ScienceEntropy
- 2021

This work introduces two quantifiers of classicality via the Jordan product and uncertainty, respectively, and then employs them to quantify decoherence from an information-theoretic perspective and studies the influence of the system on the environment.

### Decoherence predictions in a superconducting quantum processor using the steepest-entropy-ascent quantum thermodynamics framework

- PhysicsPhysical Review A
- 2022

The current stage of quantum computing technology, called noisy intermediate-scale quantum (NISQ) technology, is characterized by large errors that prohibit it from being used for real applications.…

### Gravitational decoherence of dark matter

- PhysicsJournal of Cosmology and Astroparticle Physics
- 2020

Decoherence describes the tendency of quantum sub-systems to dynamically lose their quantum character. This happens when the quantum sub-system of interest interacts and becomes entangled with an…

### Dissipative dynamics of quantum correlation quantifiers under decoherence channels

- PhysicsThe European Physical Journal Plus
- 2022

In this work, we investigate the dynamics of quantum correlations captured by entropic and geometric measures of discord under the influence of dissipative channels for widely used two qubit X state…

### Quantum gravitational decoherence from fluctuating minimal length and deformation parameter at the Planck scale

- PhysicsNature communications
- 2021

A scheme of gravitational decoherence due to quantum gravity effects is introduced and it is found that theDecoherence rate predicted by the model is extremal, being minimal in the deep quantum regime below the Planck scale and maximal in the mesoscopic regime beyond it.

### Decoherence from general relativity

- PhysicsPhysical Review D
- 2021

It is of great interest to explore matter in nontrivial quantum arrangements, including Schrödinger cat-like states. Such states are sensitive to decoherence from their environment. Recently, in Ref.…

### No Intrinsic Decoherence of Inflationary Cosmological Perturbations

- PhysicsUniverse
- 2022

After a brief summary of the four main veins in the treatment of decoherence and quantum to classical transition in cosmology since the 1980s, we focus on one of these veins in the study of quantum…

### Protective measurement of open quantum systems

- Physics
- 2020

We study protective quantum measurements in the presence of an environment and decoherence. We consider the model of a protectively measured qubit that also interacts with a spin environment during…

### Emergent classicality in general multipartite states and channels

- PhysicsQuantum
- 2021

It is shown that for any evolution of the system and environment, for everywhere in the environment excluding an O(1)-sized region the authors call the "quantum Markov blanket," any locally accessible information about the system must be approximately classical, i.e. obtainable from some fixed measurement.

We study dynamics of quantum open systems, paying special attention to these aspects of their evolution which are relevant to the transition from quantum to classical. We begin with a discussion of…

### Decoherence of quantum superpositions through coupling to engineered reservoirs

- PhysicsNature
- 2000

Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.
