Using weak value amplification angular resolution limits, we theoretically investigate the gravitational sensing of objects. By inserting a force-sensing pendulum into a weak value interferometer, the optical response can sense accelerations to a few 10’s of zepto-g $$\hbox {Hz}^{-1/2}$$Hz-1/2, with optical powers of 1 mW. We convert this precision into range and mass sensitivity, focusing in detail on simple and torsion pendula. Various noise sources present are discussed, as well as the… 

An Extension of Weak-Value Theory for Birefringence-Induced Displacement Measurements

We present an investigation into the tilt sensitivity of the canonical, optical, weak-value amplification device (COWVAD) − introduced by Duck, Stevenson, and Sudarshan in 1989 – for potential

Geometric Phases and The Sagnac Effect: Foundational Aspects and Sensing Applications

Geometric phase is a key player in many areas of quantum science and technology. In this review article, several foundational aspects of quantum geometric phases and their relations to classical



Ultrasensitive beam deflection measurement via interferometric weak value amplification.

We report on the use of an interferometric weak value technique to amplify very small transverse deflections of an optical beam. By entangling the beam's transverse degrees of freedom with the

Sensitive gravity-gradiometry with atom interferometry: progress towards an improved determination of the gravitational constant

We present here the current status of our high-sensitivity gravity-gradiometer based on atom interferometry. In our apparatus, two clouds of laser-cooled rubidium atoms are launched in a fountain

High-precision gravity measurements using atom interferometry

We have built an atom interferometer that can measure g, the local acceleration due to gravity, with a resolution of Δg/g = 2 × 10−8 after a single 1.3 s measurement cycle, 3 × 10−9 after 1 min and 1

Determination of the newtonian gravitational constant using atom interferometry.

Freely falling samples of laser-cooled rubidium atoms are used in a gravity gradiometer to probe the field generated by nearby source masses to measure the Newtonian gravitational constant G based on cold-atom interferometry.

Experimentally quantifying the advantages of weak-values-based metrology

We measure small optical beam deflections both using a Sagnac interferometer with a monitored dark port (the weak-values-based technique), or by focusing the entire beam to a split detector (the
