Quantum superposition of spacetimes obeys Einstein's equivalence principle

, 2022
We challenge the view that there is a basic conflict between the fundamental principles of Quantum Theory and General Relativity, and in particular the fact that a superposition of massive bodies would lead to a violation of the Equivalence Principle. It

On the possibility of laboratory evidence for quantum superposition of geometries

Physics Letters B, 2019
We analyse the recent proposal of measuring a quantum gravity phenomenon in the lab by entangling two mesoscopic particles gravitationally. We give a generally covariant description of this phenomenon, where the relevant effect turns out to be a quantum ...

"Quantum entanglement and superposition"

In this, manuscript we are going to taste quantum entanglement and quantum superposition.this manuscript purely based on the fundamental concept of quantum mechanics. I also going to give you look about ' broken superposition action' and 'superposition action'. I guess_ , it's going to be interesting.

Spontaneous emission in the presence of quantum mirrors

New Journal of Physics
Arrays of atoms coupled to waveguides can behave as mirrors. We consider an array of three-level atoms, with one excited and two ground levels, assuming one of the ground levels to be decoupled from the other two.

Quantum time dilation in a gravitational field [PDF]

Quantum
According to relativity, the reading of an ideal clock is interpreted as the elapsed proper time along its classical trajectory through spacetime. In contrast, quantum theory allows the association of many simultaneous trajectories with a single quantum ...

Sustained quantum coherence and entanglement in the avian compass. [PDF]

, 2011
In artificial systems, quantum superposition and entanglement typically decay rapidly unless cryogenic temperatures are used. Could life have evolved to exploit such delicate phenomena?

Direct and efficient detection of quantum superposition [PDF]

One of the most striking quantum phenomena is superposition, where one particle simultaneously inhabits different states. Most methods to verify coherent superposition are indirect, in that they require the distinct states to be recombined.
