Entanglement Swapping for Partially Entangled Qudits and the Role of Quantum Complementarity

Advanced Quantum Technologies, EarlyView.
The entanglement swapping protocol is extended to partially entangled qudit states and analyzed through complete complementarity relations. Analytical bounds on the average distributed entanglement are established, showing how the initial local predictability and entanglement constrain the operational distribution.

Metastable doubly charged Rydberg trimers

Physical Review Research
We examine an effectively one-electron system with three positive nuclei composed of a ^{87}Rb^{*} Rydberg atom interacting with a pair of ^{87}Rb^{+} ions and predict the existence of metastable vibrationally bound states of ^{87}Rb_{3}^{2+}.

Controlled multi-photon subtraction with cascaded Rydberg superatoms as single-photon absorbers

Nature Communications, 2021
Interaction of photons with Rydberg atoms can be used to modify quantum states of light. Here the authors demonstrate a controlled nonlinear quantum behavior of multi-photon subtraction in a cascaded system based on Rydberg superatoms.

Absolute frequency measurements of 85Rb nF7/2 Rydberg states using purely optical detection

, 2010
A three-step laser excitation scheme is used to make absolute frequency measurements of highly excited nF7/2 Rydberg states in 85Rb for principal quantum numbers n=33-100.

Quantum Resonator as a Directional Quantum Emitter

Advanced Quantum Technologies, EarlyView.
A single‐photon source based on a two‐photon Jaynes–Cummings system features a resonator acting as the quantum emitter rather than the two‐level system. In this configuration, enhanced efficiency, purity, and indistinguishability are achieved, while robustness against dephasing, reduced energy dissipation, and broader implementation prospects for ...

One-step achievement of robust multipartite Greenberger-Horne-Zeilinger state and controlled-phase gate via Rydberg interaction

, 2013
We present a proposal for generation of a robust tripartite Greenberger-Horne-Zeilinger state among three-individual neutral Rydberg atoms. By modulating the relation between two-photon detuning and Rydberg interaction strength $U_{ij}(r)$, an effective ...

A novel circumscription and classification for Neurolaeneae (Asteraceae)

TAXON, EarlyView.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...

Rydberg states of hydrogenlike ions in a braneworld model

European Physical Journal C: Particles and Fields, 2018
Precise measurements of optical transition frequencies between Rydberg states of hydrogen-like ions could be used to obtain an improved value of the Rydberg constant, by avoiding the uncertainties about the proton radius.

The hidden discount: Examining racial disparity in the use of suspended sentences

Criminology, EarlyView.
Abstract Extant research on criminal sentencing generally concludes that racial/ethnic disparity is concentrated in the “in–out” decision, and that racial differences in sentence lengths are small and inconsistent. However, sentence length analyses rarely focus on the fact that criminal sentences are often partially or fully suspended, creating ...
