Near-ground-state cooling of atoms optically trapped 300nm away from a hot surface

Y. Meng, A. Dareau, P. Schneeweiss +1

Laser-cooled atoms coupled to nanophotonic structures constitute a powerful research platform for the exploration of new regimes of light-matter interaction. While the initializati…

Can Two-Way Direct Communication Protocols Be Considered Secure?

Mladen Pavicic

We consider attacks on two-way quantum key distribution protocols in which an undetectable eavesdropper copies all messages in the message mode. We show that under the attacks ther…

Frequency Multiplexing for Quasi-Deterministic Heralded Single-Photon Sources

Chaitali Joshi, Alessandro Farsi, Stéphane Clemmen +2

Single-photon sources based on optical parametric processes have been used extensively for quantum information applications due to their flexibility, room-temperature operation and…

Quantum coherences of indistinguishable particles

Jan Sperling, Armando Perez-Leija, Kurt Busch +1

We study different notions of quantum correlations in multipartite systems of distinguishable and indistinguishable particles. Based on the definition of quantum coherence for a si…

Two-particle four-point correlations in dynamically disordered tight-binding networks

Armando Perez-Leija, Roberto de J. Leon-Montiel, Jan Sperling +3

We use the concept of two-particle probability amplitude to derive the stochastic evolution equation for two-particle four-point correlations in tight-binding networks affected by…

Fast forward of adiabatic control of tunneling states

Katsuhiro Nakamura, Anvar Khujakulov, Sanat Avazbaev +1

By developing the preceding work on the fast forward of transient phenomena of quantum tunneling by Khujakulov and Nakamura (Phys. Rev. {\bf A 93}, 022101 (2016) ), we propose a sc…

Dynamical Casimir effect in stochastic systems: photon-harvesting through noise

R. Román-Ancheyta, I. Ramos-Prieto, A. Perez-Leija +2

We theoretically investigate the dynamical Casimir effect in a single-mode cavity endowed with a driven off-resonant mirror. We explore the dynamics of photon generation as a funct…

Numerical Assessment and Optimization of Discrete-Variable Time-Frequency Quantum Key Distribution

Jasper Rödiger, Nicolas Perlot, Roberto Mottola +4

The discrete variables (DV) time-frequency (TF) quantum key distribution (QKD) protocol is a BB84 like protocol, which utilizes time and frequency as complementary bases. As orthog…

Spatial dispersion in atom-surface quantum friction

D. Reiche, D. A. R. Dalvit, K. Busch +1

We investigate the influence of spatial dispersion on atom-surface quantum friction. We show that for atom-surface separations shorter than the carrier's mean free path within the…
