Data for Entanglement of Orbital Angular Momentum in Non-Sequential Double Ionization

Data for publication “Entanglement of Orbital Angular Momentum in Non-Sequential Double Ionization”, available at https://arxiv.org/abs/2111.10148. A readme.txt file is included with the data. Authors Andrew S. Maxwell, Lars Bojer Madsen, Maciej Lewenstein Abstract We address orbital angular momentum (OAM) entanglement in ultrafast processes. In the strongly correlated process of non-sequential double ionization (NSDI) we demonstrate robust photoelectron entanglement. In contrast to commonly considered continuous variable  entanglement measures, the discrete OAM allows for a simpler interpretation, computation, and measurement of entanglement. The logarithmic negativity reveals that the entanglement is robust to incoherent effects and an entanglement witness is used to minimize the number of measurements to detect the entanglement, while both quantities can be directly related to coherence terms between OAM channels. We quantify the entanglement for a large range of targets and field parameters to find the most entangled photoelectron pairs. This methodology provides a general way to use OAM to quantify and measure entanglement that is well-suited to attosecond processes, and we show can be exploited to enhance imaging capabilities through correlated measurements, or could be used for generation of OAM-entangled electrons.

Experimental results dataset reported in the paper: "Temporal teleportation with pseudo-density operators: how dynamics emerges from temporal entanglement."

Temporal teleportation with pseudo-density operators: how dynamics emerges from temporal entanglement. Experimental results data-set (as reported in Figure 2 of the main paper). Caption of the Figure: Classical bound violation ∆S(l)(n) =S(l)(2n)−(2n−2) (l=T,H,S) for the multi-parameter CHSH inequalities in the temporal (red), spatial (grey) and “hybrid” (blue) domain. The dots represent the experimental results, with the uncertainty bars evaluated as statistical fluctuations among repeated measurement sets, while the solid curves show the theoretically-expected values (for the correlations belonging to the spatial domain, deviations from the ideal case due to the Vs= 0.982 estimated visibility of the generated |ψ−〉state were considered) Data-set description: Column 1 = X-coordinate: n (Number of Settings) Column 2 = Y-coordinate: ∆S(S)(n), Space-like (S) CHSH Violation [Grey color in the figure on the paper] Column 3 = Uncertainty on ∆S(S)(n) (Space-like, S, Grey in the figure on the paper),     Column 4 = Y-coordinate: ∆S(H)(n), Hybrid (H) CHSH Violation [Blue color in the figure on the paper] Column 5 = Uncertainty on ∆S(H)(n) (Hybrid, H, Blue in the figure on the paper) Column 6 = Y-coordinate: ∆S(T)(n), Time-like (T) CHSH Violation [Red color in the figure on the paper] Column 7 = Uncertainty on ∆S(T)(n) (Time-like, T, Red in the figure on the paper)

Data of the publication "Transport and entanglement growth in long-range random Clifford circuits"

Conservation laws can constrain entanglement dynamics in isolated quantum systems, manifest in a slowdown of higher Rényi entropies. Here, we explore this phenomenon in a class of long-range random Clifford circuits with U(1) symmetry where transport can be tuned from diffusive to superdiffusive. We unveil that the different hydrodynamic regimes reflect themselves in the asymptotic entanglement growth according to \(S(t) \propto t^{1/z}\) where the dynamical transport exponent z depends on the probability \(\propto r^{-\alpha}\) of gates spanning a distance r. For sufficiently small \(\alpha\), we show that the presence of hydrodynamic modes becomes irrelevant such that S(t) behaves similarly in circuits with and without conservation law. We explain our findings in terms of the inhibited operator spreading in U(1)-symmetric Clifford circuits where the emerging light cones can be understood in the context of classical Lévy flights. Our Letter sheds light on the connections between Clifford circuits and more generic many-body quantum dynamics.

Figure 4 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)

Figure 4. Glucocorticoid hormone profile in baleen from entangled bowhead whale 17B6. Baleen GC concentrations (ng/g) are shown as red circles for cortisol and orange circles for corticosterone. Sample dates were estimated based on an annual baleen growth rate of 17.5 cm/yr, starting with the harvest date (5 May 2017) on the right side of the bottom x-axis and extending retrospectively to approximately November 2005 on the left side of the x-axis (tick marks are months). Sampling locations along the baleen plate are shown on the top x-axis, and background gridlines represent the 1.25 or 2.5 cm sampling intervals used, starting at the plate base.

Figure 3. The first 10 cm of the baleen plate from bowhead whale 17B6 showing a measuring tape attached to the labial margin of the plate to guide sampling intervals. Samples were drilled every 1.25 cm (~26 d intervals) across the horizontal growth lines along the plate for the first 35 cm of growth to maximize the possibility of capturing data on the entanglement event from more recent baleen growth, and every 2.5 cm (~52 d intervals) for the reminder of the plate to establish baseline levels of GCs prior to the entanglement. Samples were collected using a hand-held Dremel rotary tool to produce pulverized baleen powder for glucocorticoid hormone analysis.

Figure 2. Fishing rope recovered from bowhead whale 17B6 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)

Figure 2. Fishing rope recovered from bowhead whale 17B6 included two types of 19 mm diameter rope. Segment (#1) appeared to be white nylon rope, while segments (#s 2, 4, 5) were blue-flecked and most likely a copolymer rope. Segment (#3) was line used by the hunters during the harvest and was not part of the whale entanglement. Fraying of the rope ends was consistent with cut ends that had not been heat sealed or whipped. It was not possible to determine the status of the gear at the time of entanglement.
