Optical synthesis of large-amplitude squeezed coherent-state superpositions with minimal resources
K. Huang, H. Le Jeannic, J. Ruaudel +10
We propose and experimentally realize a novel versatile protocol that allows the quantum state engineering of heralded optical coherent-state superpositions. This scheme relies on…
Liouville transformations and quantum reflection
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +1
Liouville transformations of Schrödinger equations preserve the scattering amplitudes while changing the effective potential. We discuss the properties of these gauge transformatio…
Generating and verifying entangled itinerant microwave fields with efficient and independent measurements
H. S. Ku, W. F. Kindel, F. Mallet +5
By combining a squeezed propagating microwave field and an unsqueezed vacuum field on a hybrid (microwave beam-splitter), we generate entanglement between the two output modes. We…
Demonstration of a memory for tightly guided light in an optical nanofiber
B. Gouraud, D. Maxein, A. Nicolas +2
We report the experimental observation of slow-light and coherent storage in a setting where light is tightly confined in the transverse directions. By interfacing a tapered optica…
Spin Wave Diffraction Control and Read-out with a Quantum Memory for Light
Gabriel Hétet, David Guéry-Odelin
A scheme for control and read-out of diffracted spins waves to propagating light fields is presented. Diffraction is obtained via sinusoidally varying lights shifts and ideal one-t…
Coherent spin control at the quantum level in an ensemble-based optical memory
Pierre Jobez, Cyril Laplane, Nuala Timoney +4
Long-lived quantum memories are essential components of a long-standing goal of remote distribution of entanglement in quantum networks. These can be realized by storing the quantu…
