Coherent storage of microwave excitations in rare-earth nuclear spins
Gary Wolfowicz, Hannes Maier-Flaig, Robert Marino +4
Interfacing between various elements of a computer - from memory to processors to long range communication - will be as critical for quantum computers as it is for classical comput…
Quantum reflection and Liouville transformations from wells to walls
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +1
Liouville transformations map in a rigorous manner one Schrödinger equation into another, with a changed scattering potential. They are used here to transform quantum reflection of…
Landau levels for discrete-time quantum walks in artificial magnetic fields
Pablo Arnault, Fabrice Debbasch
A new family of 2D discrete-time quantum walks (DTQWs) is presented and shown to coincide, in the continuous limit, with the Dirac dynamics of a spin 1/2 fermion coupled to a const…
Fluctuations of the Casimir potential above a disordered medium
Nicolas Cherroret, Romain Guérout, Astrid Lambrecht +1
We study the statistical fluctuations of the Casimir potential felt by an atom approaching a dielectric disordered medium. Starting from a microscopic model for the disorder, we ca…
Casimir-Polder induced Rabi oscillations
M. Donaire, M. -P. Gorza, A. Maury +2
We show that the Casimir-Polder interaction may induce coherent oscillations between degenerate atomic states. We illustrate this effect by computing the Casimir-Polder induced Rab…
Quantum networks generation based on four-wave mixing
Yin Cai, Jingliang Feng, Hailong Wang +4
We present a scheme to realize versatile quantum networks by cascading several four-wave mixing (FWM) processes in warm rubidium vapors. FWM is an efficient nonlinear pro…
Geometric origin of negative Casimir entropies: A scattering-channel analysis
Gert-Ludwig Ingold, Stefan Umrath, Michael Hartmann +4
Negative values of the Casimir entropy occur quite frequently at low temperatures in arrangements of metallic objects. The physical reason lies either in the dissipative nature of…
Atomic quantum memory for multimode frequency combs
Z. Zheng, O. Mishina, N. Treps +1
We propose a Raman quantum memory scheme that uses several atomic ensembles to store and retrieve the multimode highly entangled state of an optical quantum frequency comb, such as…
Coherent control of light transport in a dense and disordered atomic ensemble
A. S. Sheremet, D. F. Kornovan, L. V. Gerasimov +3
Light transport in a dense and disordered cold atomic ensemble, where the cooperation of atomic dipoles essentially modifies their coupling with the radiation modes, offers an alte…
Massless Dirac Equation from Fibonacci Discrete-Time Quantum Walk
Giuseppe Di Molfetta, Lauchlan Honter, Ben B. Luo +2
Discrete-time quantum walks can be regarded as quantum dynamical simulators since they can simulate spatially discretized Schrödinger, massive Dirac, and Klein-Gordon equations. He…
Spectral Noise Correlations of an Ultrafast Frequency Comb
Roman Schmeissner, Jonathan Roslund, Claude Fabre +1
Cavity-based noise detection schemes are combined with ultrafast pulse shaping as a means to diagnose the spectral correlations of both the amplitude and phase noise of an ultrafas…
Quantum state tomography of orbital angular momentum photonics qubits via a projection-based technique
Adrien Nicolas, Lucile Veissier, Elisabeth Giacobino +2
While measuring the orbital angular momentum state of bright light beams can be performed using imaging techniques, a full characterization at the single-photon level is challengin…
Casimir forces
S. Reynaud, A. Lambrecht
The present notes are organized as the lectures given at the Les Houches Summer School "Quantum Optics and Nanophotonics" in August 2013. The first section contains an introduction…
Full multipartite entanglement of frequency comb Gaussian states
S. Gerke, J. Sperling, W. Vogel +4
An analysis is conducted of the multipartite entanglement for Gaussian states generated by the parametric down-conversion of a femtosecond frequency comb. Using a recently introduc…
Heating of trapped ultracold atoms by collapse dynamics
Franck Laloë, William J. Mullin, Philip Pearle
{The Continuous Spontaneous Localization (CSL) theory alters the Schrödinger equation. It describes wave function collapse as a dynamical process instead of an ill-defined postulat…
Discrete-time Quantum Walks in random artificial Gauge Fields
G. Di Molfetta, F. Debbasch
Discrete-time quantum walks (DTQWs) in random artificial electric and gravitational fields are studied analytically and numerically. The analytical computations are carried by a ne…
Photon emission and absorption of a single ion coupled to an optical fiber-cavity
M. Steiner, H. M. Meyer, J. Reichel +1
We present a light-matter interface which consists of a single Yb ion coupled to an optical fiber-cavity. We observe that photons at 935 nm are mainly emitted into the…
Entanglement on macroscopic scales in a resonantly laser-excited atomic ensemble
S. Camalet
We show that two groups of slow two-level atoms in a weak resonant laser field, are entangled. The considered groups can be separated by a macroscopic distance, and be parts of a l…
Arbitrary quantum-state preparation of a harmonic oscillator via optimal control
Katharina Rojan, Daniel M. Reich, Igor Dotsenko +3
The efficient initialization of a quantum system is a prerequisite for quantum technological applications. Here we show that several classes of quantum states of a harmonic oscilla…
Witnessing single-photon entanglement with local homodyne measurements: analytical bounds and robustness to losses
Melvyn Ho, Olivier Morin, Jean-Daniel Bancal +3
Single-photon entanglement is one of the primary resources for quantum networks, including quantum repeater architectures. Such entanglement can be revealed with only local homodyn…
Negative Casimir Entropies in Nanoparticle Interactions
K. A. Milton, Romain Guérout, Gert-Ludwig Ingold +2
Negative entropy has been known in Casimir systems for some time. For example, it can occur between parallel metallic plates modeled by a realistic Drude permittivity. Less well kn…
Casimir effect from a scattering approach
Gert-Ludwig Ingold, Astrid Lambrecht
The Casimir force is a spectacular consequence of the existence of vacuum fluctuations and thus deserves a place in courses on quantum theory. We argue that the scattering approach…

R. Guérout, A. Lambrecht, K. A. Milton +1
We carefully re-examine the conditions of validity for the consistent derivation of the Lifshitz-Matsubara sum formula for the Casimir pressure between metallic plane mirrors. We r…
