Quantum state tomography with non-instantaneous measurements, imperfections and decoherence
Pierre Six, Philippe Campagne-Ibarcq, Igor Dotsenko +3
Tomography of a quantum state is usually based on positive operator-valued measure (POVM) and on their experimental statistics. Among the available reconstructions, the maximum-lik…
Casimir effect and quantum reflection
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +1
The GBAR experiment will time the free fall of cold antihydrogen atoms dropped onto an annihilation plate to test the universality of free fall on antimatter. In this contribution,…
Experimental quantum state engineering with time-separated heraldings from a continuous-wave light source: a temporal-mode analysis
K. Huang, H. Le Jeannic, V. B. Verma +7
Conditional preparation is a well-established technique for quantum state engineering of light. A general trend is to increase the number of heralding detection events in such real…
Observing quantum state diffusion by heterodyne detection of fluorescence
P. Campagne-Ibarcq, P. Six, L. Bretheau +4
A qubit can relax by fluorescence, which prompts the release of a photon into its electromagnetic environment. By counting the emitted photons, discrete quantum jumps of the qubit…
Casimir torque between nanostructured plates
R. Guérout, C. Genet, A. Lambrecht +1
We investigate in detail the Casimir torque induced by quantum vacuum fluctuations between two nanostructured plates. Our calculations are based on the scattering approach and take…
Statistical approach to Casimir-Polder potentials in heterogeneous media
Nicolas Cherroret, Romain Guérout, Astrid Lambrecht +1
We explore the statistical properties of the Casimir-Polder potential between a dielectric sphere and a three-dimensional heterogeneous medium, by means of extensive numerical simu…
Quantum Uncertainty in the Beam Width of Spatial Optical Modes
Vanessa Chille, Peter Banzer, Andrea Aiello +4
We theoretically investigate the quantum uncertainty in the beam width of transverse optical modes and, for this purpose, define a corresponding quantum operator. Single mode state…
Quantum dynamics of an electromagnetic mode that cannot contain N photons
Landry Bretheau, Philippe Campagne-Ibarcq, Emmanuel Flurin +2
Electromagnetic modes are instrumental in building quantum machines. In this experiment, we introduce a method to manipulate these modes by effectively controlling their phase spac…
Focus on Quantum Memories
Gavin Brennen, Elisabeth Giacobino, Christoph Simon
Quantum memories are essential for quantum information processing and long-distance quantum communication. The field has recently seen a lot of progress, and the present focus issu…
Two-photon quantum walk in a multimode fiber
Hugo Defienne, Marco Barbieri, Ian A. Walmsley +2
Multi-photon propagation in connected structures - a quantum walk - offers the potential for simulating complex physical systems and provides a route to universal quantum computati…
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…
Effect of charging on CdSe/CdS dot-in-rods single-photon emission
M. Manceau, S., Vezzoli +6
The photon statistics of CdSe/CdS dot-in-rods nanocrystals is studied with a method involving post-selection of the photon detection events based on the photoluminescence count rat…
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…
