Reconstruction of photon number conditioned states using phase randomized homodyne measurements
H. M. Chrzanowski, S. M. Assad, Julien Bernu +5
We experimentally demonstrate the reconstruction of a photon number conditioned state without using a photon number discriminating detector. By using only phase randomized homodyne…
Dual-rail optical gradient echo memory
Daniel B. Higginbottom, Jiao Geng, Geoff T. Campbell +7
We introduce a scheme for the parallel storage of frequency separated signals in an optical memory and demonstrate that this dual-rail storage is a suitable memory for high fidelit…
Highly efficient optical quantum memory with long coherence time in cold atoms
Y. -W. Cho, G. T. Campbell, J. L. Everett +7
Optical quantum memory is an essential element for long distance quantum communication and photonic quantum computation protocols. The practical implementation of such protocols re…
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…
Freezing a Coherent Field Growth in a Cavity by Quantum Zeno Effect
Julien Bernu, Samuel Deléglise, Clément Sayrin +5
We have frozen the coherent evolution of a field in a cavity by repeated measurements of its photon number. We use circular Rydberg atoms dispersively coupled to the cavity mode fo…
Process tomography of field damping and measurement of Fock state lifetimes by quantum non-demolition photon counting in a cavity
M. Brune, J. Bernu, C. Guerlin +7
The relaxation of a quantum field stored in a high- superconducting cavity is monitored by non-resonant Rydberg atoms. The field, subjected to repetitive quantum non-demolition…
