All-atomic source of squeezed vacuum with full pulse-shape control
We report on the generation of pulses of a low-frequency squeezed vacuum with noise suppression >2 dB below the standard quantum limit in a hot resonant 87Rb vapour with polarization self-rotation. We demonstrate the possibility of precisely controlling the temporal profile of the squeezed noise quadrature by applying a calibrated longitudinal magnetic field, without degrading the maximum amoun...
متن کاملSingle-mode source of bright squeezed vacuum
Bright squeezed vacuum (BSV) can be obtained at the output of a high-gain traveling-wave optical parametric amplifier with the vacuum at the input. Without any special efforts, it is multimode both spatially and temporally. This means it comes as not Fourier-limited pulses and not diffractionlimited beams. At the same time, what theory describes well and what is required for most applications i...

متن کاملA squeezed light source operated under high vacuum.
Non-classical squeezed states of light are becoming increasingly important to a range of metrology and other quantum optics applications in cryptography, quantum computation and biophysics. Applications such as improving the sensitivity of advanced gravitational wave detectors and the development of space-based metrology and quantum networks will require robust deployable vacuum-compatible sour...
متن کاملSqueezed Vacuum Interferometry
A high-sensitive interferometric scheme is presented. It is based on homodyne detection and squeezed vacuum phase properties. The resulting phase sensitivity scales as ' 1 4 n 1 with respect to input photons number. Accepted for publication in Modern Phyiscs Letters B E-mail Address: [email protected]
