Indistinguishable photons from a trapped-ion quantum network node
M. Meraner, A. Mazloom, V. Krutyanskiy +7
Trapped atomic ions embedded in optical cavities are a promising platform to enable long-distance quantum networks and their most far-reaching applications. Here we achieve and ana…
Bell correlations between light and vibration at ambient conditions
Santiago Tarrago Velez, Vivishek Sudhir, Nicolas Sangouard +1
Time-resolved Raman spectroscopy techniques offer various ways to study the dynamics of molecular vibrations in liquids or gases and optical phonons in crystals. While these techni…
Quantum non-demolition state detection and spectroscopy of single trapped molecules
Mudit Sinhal, Ziv Meir, Kaveh Najafian +2
Trapped atoms and ions are among the best controlled quantum systems which find widespread applications in quantum information, sensing and metrology. For molecules, however, a sim…
Unsupervised identification of topological order using predictive models
Eliska Greplova, Agnes Valenti, Gregor Boschung +3
Machine-learning driven models have proven to be powerful tools for the identification of phases of matter. In particular, unsupervised methods hold the promise to help discover ne…
Quantum Synchronization on the IBM Q System
Martin Koppenhöfer, Christoph Bruder, Alexandre Roulet
We report the first experimental demonstration of quantum synchronization. This is achieved by performing a digital simulation of a single spin- limit-cycle oscillator on the qu…
What is the minimum CHSH score certifying that a state resembles the singlet?
Xavier Valcarce, Pavel Sekatski, Davide Orsucci +3
A quantum state can be characterized from the violation of a Bell inequality. The well-known CHSH inequality for example can be used to quantify the fidelity (up to local isometrie…
Cavity-enhanced Raman scattering for in situ alignment and characterization of solid-state microcavities
Daniel Riedel, Sigurd Flågan, Patrick Maletinsky +1
We report cavity-enhanced Raman scattering from a single-crystal diamond membrane embedded in a highly miniaturized fully-tunable Fabry-Pérot cavity. The Raman intensity is enhance…
State-selective coherent motional excitation as a new approach for the manipulation, spectroscopy and state-to-state chemistry of single molecular ions
Ziv Meir, Gregor Hegi, Kaveh Najafian +2
We present theoretical and experimental progress towards a new approach for the precision spectroscopy, coherent manipulation and state-to-state chemistry of single isolated molecu…
Waveguide-coupled single collective excitation of atomic arrays
N. V. Corzo, J. Raskop, A. Chandra +3
Considerable efforts have been recently devoted to combining ultracold atoms and nanophotonic devices to obtain not only better scalability and figures of merit than in free-space…
Entanglement between identical particles is a useful and consistent resource
Benjamin Morris, Benjamin Yadin, Matteo Fadel +3
The existence of fundamentally identical particles represents a foundational distinction between classical and quantum mechanics. Due to their exchange symmetry, identical particle…
How post-selection affects device-independent claims under the fair sampling assumption
Davide Orsucci, Jean-Daniel Bancal, Nicolas Sangouard +1
Device-independent certifications employ Bell tests to guarantee the proper functioning of an apparatus from the sole knowledge of observed measurement statistics, i.e. without ass…
Heralded dissipative preparation of nonclassical states in a Kerr oscillator
Martin Koppenhöfer, Christoph Bruder, Niels Lörch
We present a heralded state preparation scheme for driven nonlinear open quantum systems. The protocol is based on a continuous photon counting measurement of the system's decay ch…
Entanglement and non-locality between disparate solid-state quantum memories mediated by photons
Marcel. li Grimau Puigibert, Mohsen Falamarzi Askarani, Jacob H. Davidson +7
Entangling quantum systems with different characteristics through the exchange of photons is a prerequisite for building future quantum networks. Proving the presence of entangleme…
Optimal distributed sensing in noisy environments
