We show that when the gravitational field is treated quantum-mechanically, it induces fluctuations -- noise -- in the lengths of the arms of gravitational wave detectors. The characteristics of the noise depend on the quantum state of the gravitational field, and can be calculated exactly in several interesting cases. For coherent states the noise is very small, but it can be greatly enhanced in thermal and (especially) squeezed states. Detection of this fundamental noise would constitute… 
Signatures of the quantization of gravity at gravitational wave detectors
We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochastic fluctuations
Quantum Mechanics of Gravitational Waves.
TLDR
The gravitational field is treated as a quantum field and it is found that falling bodies in gravity are subject to random fluctuations ("noise") whose characteristics depend on the quantum state of the gravitational field.
Noise and decoherence induced by gravitons
We study quantum noise and decoherence induced by gravitons. We derive a Langevin equation of geodesic deviation in the presence of gravitons. The amplitude of noise correlations tells us that large
Quantum State Evolution in an Environment of Cosmological Perturbations
We study the pure and thermal states of quantized scalar and tensor perturbations in various epochs of Universe evolution. We calculate the density matrix of non-relativistic particles in an
Gravitational decoherence of photons
Models of gravitational decoherence are not commonly applied to ultra-relativistic systems, including photons. As a result, few quantum optical tests of gravitational decoherence have been developed.
Gravitational effects in macroscopic quantum systems: a first-principles analysis
We analyze the weak-field limit of general relativity with matter and its possible quantisations. This analysis aims toward a predictive quantum theory to provide a first-principles description of
Light-ray operators, detectors and gravitational event shapes
Abstract Light-ray operators naturally arise from integrating Einstein equations at null infinity along the light-cone time. We associate light-ray operators to physical detectors on the celestial
A manifestly covariant theory of multifield stochastic inflation in phase space: solving the discretisation ambiguity in stochastic inflation
TLDR
A path-integral derivation of Langevin equations is developed, which solves conceptual issues of the heuristic approach made at the level of the classical equations of motion, and allows in principle to compute corrections to the stochastic formalism.

TLDR
The old framework of semiclassical gravity is extended to that based on a Langevin-type equation, where the dynamics of the fluctuations of spacetime is driven by the quantum fluctuations of the matter field, useful for the investigation of quantum processes in the early Universe involving fluctuations, vacuum instability, and phase transition phenomena as well as the nonequilibrium thermodynamics of black holes.
Inflation and squeezed quantum states.
TLDR
The squeezed state formalism provides an interesting framework within which to study the amplification process, but it is concluded that it does not provide us with any new physical results.

We give a summary of the status of currentresearch in stochastic semiclassical gravity and suggestdirections for further investigations. This theorygeneralizes the semiclassical Einstein equation to

Reproducing GW150914: the first observation of gravitational waves from a binary black hole merger
TLDR
This work attempts to reproduce the result presented in the GW150914 discovery paper using publicly available code on the Open Science Grid, and shows that it can reproduce the main result but it cannot exactly reproduce the LIGO analysis as the original dataset used is not public.
