Demonstrating various quantum effects with two entangled laser beams
B. Hage, J. Janoušek, S. Armstrong +5
We report on the preparation of entangled two mode squeezed states of yet unseen quality. Based on a measurement of the covariance matrix we found a violation of the Reid and Drumm…
Delay of Squeezing and Entanglement using Electromagnetically Induced Transparency in a Vapour Cell
G. Hétet, B. C. Buchler, O. Glöckl +4
We demonstrate experimentally the delay of squeezed light and entanglement using Electromagnetically Induced Transparency (EIT) in a rubidium vapour cell. We perform quadrature amp…
Squeezing and entanglement delay using slow light
Amy Peng, Mattias Johnsson, W. P. Bowen +3
We examine the interaction of a weak probe with atoms in a lambda-level configuration under the conditions of electromagnetically induced transparency (EIT). In contrast to pre…
Squeezed light at sideband frequencies below 100 kHz from a single OPA
R. Schnabel, H. Vahlbruch, A. Franzen +6
Quantum noise of the electromagnetic field is one of the limiting noise sources in interferometric gravitational wave detectors. Shifting the spectrum of squeezed vacuum states dow…
Recovery of continuous wave squeezing at low frequencies
W. P. Bowen, R. Schnabel, N. Treps +2
We propose and demonstrate a system that produces squeezed vacuum using a pair of optical parametric amplifiers. This scheme allows the production of phase sidebands on the squeeze…
Classical and quantum signatures of competing chi(2) nonlinearities
A. G. White, P. K. Lam, M. S. Taubman +4
We report the first observation of the quantum effects of competing nonlinearities. We also report new classical signatures of competition, namely clamping of the second…
