• ### Experimental Certification of Nonclassicality via Phase-Space Inequalities

Author(s): Nicola Biagi, Martin Bohmann, Elizabeth Agudelo, Marco Bellini, and Alessandro Zavatta In spite of its fundamental importance in quantum science and technology, the experimental certification of nonclassicality is still a challenging task, especially in realistic scenarios where losses and noise imbue the system. Here, we present the first experimental implementation of the recently i... [Phys. Rev. Lett. 126, 023605] Published Fri...
• ### Shortcuts to Adiabaticity for the Quantum Rabi Model: Efficient Generation of Giant Entangled Cat States via Parametric Amplification

Author(s): Ye-Hong Chen, Wei Qin, Xin Wang, Adam Miranowicz, and Franco Nori We propose a method for the fast generation of nonclassical ground states of the Rabi model in the ultrastrong and deep-strong coupling regimes via the shortcuts-to-adiabatic (STA) dynamics. The time-dependent quantum Rabi model is simulated by applying parametric amplification to the Jaynes-Cumming... [Phys. Rev. Lett. 126, 023602] Published Wed Jan 13, 2021
• ### Experimental Reconstruction of the Few-Photon Nonlinear Scattering Matrix from a Single Quantum Dot in a Nanophotonic Waveguide

Author(s): Hanna Le Jeannic, Tomás Ramos, Signe F. Simonsen, Tommaso Pregnolato, Zhe Liu, Rüdiger Schott, Andreas D. Wieck, Arne Ludwig, Nir Rotenberg, Juan José García-Ripoll, and Peter Lodahl Coherent photon-emitter interfaces offer a way to mediate efficient nonlinear photon-photon interactions, much needed for quantum information processing. Here we experimentally study the case of a two-level emitter, a quantum dot, coupled to a single optical...
• ### Double-Electromagnetically-Induced-Transparency Ground-State Cooling of Stationary Two-Dimensional Ion Crystals

Author(s): Mu Qiao, Ye Wang, Zhengyang Cai, Botao Du, Pengfei Wang, Chunyang Luan, Wentao Chen, Heung-Ryoul Noh, and Kihwan Kim We theoretically and experimentally investigate double-electromagnetically-induced transparency (double-EIT) cooling of two-dimensional ion crystals confined in a Paul trap. The double-EIT ground-state cooling is observed for ${^{171}\mathrm{Yb}}^{+}$ ions with a clock state, for which EIT cooling h... [Phys. Rev....
• ### Using Circular Dichroism to Control Energy Transfer in Multiphoton Ionization

Author(s): A. H. N. C. De Silva, D. Atri-Schuller, S. Dubey, B. P. Acharya, K. L. Romans, K. Foster, O. Russ, K. Compton, C. Rischbieter, N. Douguet, K. Bartschat, and D. Fischer Chirality causes symmetry breaks in a large variety of natural phenomena ranging from particle physics to biochemistry. We investigate one of the simplest conceivable chiral systems, a laser-excited, oriented, effective one-electron Li target. Prepared in a polarized...
• ### Statistical Benchmarking of Scalable Photonic Quantum Systems

Author(s): J. Tiedau, M. Engelkemeier, B. Brecht, J. Sperling, and C. Silberhorn Targeting at the realization of scalable photonic quantum technologies, the generation of many photons, their propagation in large optical networks, and a subsequent detection and analysis of sophisticated quantum correlations are essential for the understanding of macroscopic quantum systems. In th... [Phys. Rev. Lett. 126, 023601] Published Tue Jan 12, 2021
• ### Universal Dimerized Quantum Droplets in a One-Dimensional Lattice

Author(s): Ivan Morera, Grigori E. Astrakharchik, Artur Polls, and Bruno Juliá-Díaz The ground-state properties of two-component bosonic mixtures in a one-dimensional optical lattice are studied both from few- and many-body perspectives. We rely directly on a microscopic Hamiltonian with attractive intercomponent and repulsive intracomponent interactions to demonstrate the formatio... [Phys. Rev.
