Two-photon interference from a bright single photon source at telecom wavelengths
Je-Hyung Kim, Tao Cai, Christopher J. K. Richardson +2
Long-distance quantum communication relies on the ability to efficiently generate and prepare single photons at telecom wavelengths. In many applications these photons must also be…
A strong loophole-free test of local realism
Lynden K. Shalm, Evan Meyer-Scott, Bradley G. Christensen +31
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parti…
High teleportation rates using cold-atom ensemble based quantum repeaters with Rydberg blockade
Neal Solmeyer, Xiao Li, Qudsia Quraishi
We present a simplified version of a repeater protocol in a cold neutral-atom ensemble with Rydberg excitations optimized for two-node entanglement generation and describe a protoc…
A practical phase gate for producing Bell violations in Majorana wires
David J. Clarke, Jay D. Sau, Sankar Das Sarma
The Gottesman-Knill theorem holds that operations from the Clifford group, when combined with preparation and detection of qubit states in the computational basis, are insufficient…
Anomalous broadening in driven dissipative Rydberg systems
E. A. Goldschmidt, T. Boulier, R. C. Brown +5
We observe interaction-induced broadening of the two-photon 5s-18s transition in 87Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by nearly two orders o…
Renyi information from entropic effects in one higher dimension
Mohammad F. Maghrebi
Computing entanglement entropy and its cousins is often challenging even in the simplest continuum and lattice models, partly because such entropies depend nontrivially on all geom…
Many-body localization in a quantum simulator with programmable random disorder
Jacob Smith, Aaron Lee, Philip Richerme +6
When a system thermalizes it loses all local memory of its initial conditions. This is a general feature of open systems and is well described by equilibrium statistical mechanics.…
Serialized Quantum Error Correction Protocol for High-Bandwidth Quantum Repeaters
Andrew N. Glaudell, Edo Waks, Jacob M. Taylor
Advances in single photon creation, transmission, and detection suggest that sending quantum information over optical fibers may have losses low enough to be correctable using a qu…
Flight of a heavy particle nonlinearly coupled to a quantum bath
Mohammad F. Maghrebi, Matthias Krüger, Mehran Kardar
Fluctuation and dissipation are by-products of coupling to the `environment.' The Caldeira-Leggett model, a successful paradigm of quantum Brownian motion, views the environment as…
Framework for learning agents in quantum environments
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In this paper we provide a broad framework for describing learning agents in general quantum environments. We analyze the types of classically specified environments which allow fo…
Multi-channel entanglement distribution using spatial multiplexing from four-wave mixing in atomic vapor
Prasoon Gupta, Travis Horrom, Brian E. Anderson +2
Four-wave mixing in atomic vapor allows for the generation of multi-spatial-mode states of light containing many pairs of two-mode entangled vacuum beams. This in principle can be…
A Quantum Model for Entropic Springs
Chiao-Hsuan Wang, Jacob M. Taylor
Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we develop a quantum-mechanical model of a bath of spins coupled to the elasticity of a…
Optimal excitation conditions for indistinguishable photons from quantum dots
Tobias Huber, Ana Predojević, Daniel Föger +2
In this letter, we present a detailed, all optical study of the influence of different excitation schemes on the indistinguishability of single photons from a single InAs quantum d…
Sensing Atomic Motion from the Zero Point to Room Temperature with Ultrafast Atom Interferometry
K. G. Johnson, B. Neyenhuis, J. Mizrahi +2
We sense the motion of a trapped atomic ion using a sequence of state-dependent ultrafast momentum kicks. We use this atom interferometer to characterize a nearly-pure quantum stat…
Entangling two transportable neutral atoms via local spin exchange
A. M. Kaufman, B. J. Lester, M. Foss-Feig +3
To advance quantum information science a constant pursuit is the search for physical systems that meet the stringent requirements for creating and preserving quantum entanglement.…
Coherence and degree of time-bin entanglement from quantum dots
Tobias Huber, Laurin Ostermann, Maximilian Prilmüller +4
We report on the generation of time-bin entangled photon pairs from a semiconductor quantum dot via pulsed resonant biexciton generation. Based on theoretical modeling we optimized…
Self-heterodyne detection of the {\it in-situ} phase of an atomic-SQUID
Ranchu Mathew, Avinash Kumar, Stephen Eckel +4
We present theoretical and experimental analysis of an interferometric measurement of the {\it in-situ} phase drop across and current flow through a rotating barrier in a toroidal…
Chaotic scattering in the presence of a dense set of overlapping Feshbach resonances
Krzysztof Jachymski, Paul S. Julienne
Complex quantum systems consisting of large numbers of strongly coupled states exhibit characteristic level repulsion, leading to a non-Poisson spacing distribution which can be de…
A quantum phase switch between a single solid-state spin and a photon
Shuo Sun, Hyochul Kim, Glenn S. Solomon +1
Strong interactions between single spins and photons are essential for quantum networks and distributed quantum computation. They provide the necessary interface for entanglement d…

Edward B. Flagg, Glenn S. Solomon
We propose a method to read-out the spin-state of an electron in a quantum dot in a Voigt geometry magnetic field using cycling transitions induced by the AC Stark effect. We show…
