Quantum key distribution implemented with d-level time-bin entangled photons.

High-dimensional photon states (qudits) are pivotal to enhance the information capacity, noise robustness, and data rates of quantum communications. Time-bin entangled qudits are promising candidates for implementing high-dimensional quantum communications over optical fiber networks with processing rates approaching those of classical telecommunications. However, their use is hindered by phase instability, timing inaccuracy, and low scalability of interferometric schemes needed for time-bin processing.

Emerging therapeutic approaches for Tourette syndrome and other tic disorders - a systematic review of current clinical trials.

Tourette syndrome and other tic disorders are prevalent neurodevelopmental disorders typically treated with behavioral techniques or pharmacological interventions, primarily antipsychotics. However, many patients do not achieve sufficient response to conventional treatments, underscoring the need for further research in this area. To provide a comprehensive overview of ongoing research activities, we systematically searched the clinical registries of the World Health Organization (WHO) and of the United States National Institutes of Health (NIH) for currently planned or ongoing registered clinical studies.

Quantum-State Renormalization in Semiconductor Nanoparticles.

A single photoexcited electron-hole pair within a polar semiconductor nanocrystal (SNC) alters the charge screening and shielding within it. Perturbations of the crystal lattice and of the valence and conduction bands result, and the quantum-confinement states in a SNC shift uniquely with a dependence on the states occupied by the carriers. This shifting is termed quantum-state renormalization (QSR).

Influence of pediatric ERCP positioning on procedural outcomes: A single-center study.

Objectives: Endoscopic retrograde cholangiopancreatography (ERCP) is traditionally done in the prone position. In pediatrics, patient anatomy and anesthesia practices are considerations that affect procedural success and anesthesia time. The aim of our study was to evaluate the safety, procedural success, and efficiency of pediatric ERCP in the prone versus supine positions.

Face matching as a majority: Getting the best from a crowd.

For unfamiliar faces, deciding whether two photographs depict the same person or not can be difficult. One way to substantially improve accuracy is to defer to the 'wisdom of crowds' by aggregating responses across multiple individuals. However, there are several methods available for doing this.
