The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves of astrophysical origin. Direct detection of gravitational waves holds the… (More)
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitationalwave sources of astrophysical and cosmological origin. It should… (More)

We analyzed the available LIGO data coincident with GRB 070201, a short-duration, hard-spectrum -ray burst (GRB) whose electromagnetically determined sky position is coincident with the spiral arms… (More)
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 relativity1 and are generated,… (More)
Squeezing of light's quantum noise requires temporal rearranging of photons. This again corresponds to creation of quantum correlations between individual photons. Squeezed light is a nonclassical… (More)
Squeezed states of light belong to the most prominent nonclassical resources. They have compelling applications in metrology, which has been demonstrated by their routine exploitation for improving… (More)
We report on the first long-term application of squeezed vacuum states of light to improve the shot-noise-limited sensitivity of a gravitational-wave observatory. In particular, squeezed vacuum was… (More)
We report the experimental realization of squeezed quantumstates of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier frequency band down… (More)
