We investigate decoherence of quantum superpositions induced by gravitational time dilation and spontaneous emission between two atomic levels. It has been shown that gravitational time dilation can be an universal decoherence source. Here, we consider decoherence induced by gravitational time dilation only in the situation of spontaneous emission. Then, we obtain that the coherence of particle's position state depends on reference frame due to the time dilation changing the distinguishability…

Universal Decoherence under Gravity: A Perspective through the Equivalence Principle.
It is proposed that dephasing due to gravity may in fact take place for certain modifications to the gravitational potential where the equivalence principle is violated.
On Gravity's role in Quantum State Reduction
The stability of a quantum superposition of two different stationary mass distributions is examined, where the perturbing effect of each distribution on the space-time structure is taken into
Time-Delayed Quantum Feedback Control.
It is shown that the dynamics can be mapped onto a fictitious series of cascaded quantum systems, where the system is driven by past versions of itself, to create a unidirectional feedback loop.
Decoherence, einselection, and the quantum origins of the classical
as quantum engineering. In the past two decades it has become increasingly clear that many (perhaps all) of the symptoms of classicality can be induced in quantum systems by their environments. Thus
Universal decoherence due to gravitational time dilation
Gravity and quantum mechanics are expected to meet at extreme energy scales, but time dilation could induce decoherence even at low energies affecting microscopic objects—a prospect that could be
Decoherence, the measurement problem, and interpretations of quantum mechanics
Environment-induced decoherence and superselection have been a subject of intensive research over the past two decades, yet their implications for the foundational problems of quantum mechanics, most
Coarse graining makes it hard to see micro-macro entanglement.
It is shown that the distance between the probability distributions of results for the two cloners approaches zero for a fixed moderate amount of coarse graining, and proving the presence of micro-macro entanglement becomes progressively harder as the system size increases.

A new parameter-free unification of micro- and macrodynamics is constructed and gravitational measures for reducing macroscopic quantum fluctuations of the mass density are applied to lead to classical trajectories in the Macroscopic limit of translational motion.
Persistence of coherent quantum dynamics at strong dissipation.
The quantum dynamics of a two-state system coupled to a bosonic reservoir with sub-Ohmic spectral density is investigated for strong friction. Numerically exact path integral Monte Carlo methods
Transfer of nonclassical properties from a microscopic superposition to macroscopic thermal states in the high temperature limit.
This work is motivated by an analogy of Schrödinger's cat paradox, where the state corresponding to the virtual cat is a mixed thermal state with a large average photon number.
