Approaching the motional ground state of a 10 kg object
Chris Whittle, Evan D. Hall, Sheila Dwyer +197
The motion of a mechanical object -- even a human-sized object -- should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: th…
Quantum correlations between the light and kilogram-mass mirrors of LIGO
Haocun Yu, L. McCuller, M. Tse +196
Measurement of minuscule forces and displacements with ever greater precision encounters a limit imposed by a pillar of quantum mechanics: the Heisenberg uncertainty principle. A l…
Classical hallmarks of macroscopic quantum wave function propagation
James M. Feagin, John S. Briggs
The precise connection between quantum wave functions and the underlying classical trajectories often is presented rather vaguely by practitioners of quantum mechanics. Here we dem…
A delayed choice quantum eraser explained by the transactional interpretation of quantum mechanics
H. Fearn
This paper explains the delayed choice quantum eraser of Kim et al. in terms of the transactional interpretation of quantum mechanics by John Cramer. It is kept deliberately mathem…
Enhancing the sensitivity of the LIGO gravitational wave detector by using squeezed states of light
The LIGO Scientific Collaboration
Nearly a century after Einstein first predicted the existence of gravitational waves, a global network of earth-based gravitational wave observatories is seeking to directly detect…
A gravitational wave observatory operating beyond the quantum shot-noise limit: Squeezed light in application
The LIGO Scientific Collaboration
Around the globe several observatories are seeking the first direct detection of gravitational waves (GWs). These waves are predicted by Einstein's General Theory of Relativity [Ei…
