Experimental Quantum Non-Gaussian Coincidences of Entangled Photons.

Quantum non-Gaussianity, a more potent and highly useful form of nonclassicality, excludes all convex mixtures of Gaussian states and Gaussian parametric processes generating them. Here, for the first time, we conclusively test quantum non-Gaussian coincidences of entangled photon pairs with the Clauser-Horne-Shimony-Holt-Bell factor S=2.328±0.

Coherence-Based Operational Nonclassicality Criteria.

The nonclassicality of quantum states is a fundamental resource for quantum technologies and quantum information tasks, in general. In particular, a pivotal aspect of quantum states lies in their coherence properties, encoded in the nondiagonal terms of their density matrix in the Fock-state bosonic basis. We present operational criteria to detect the nonclassicality of individual quantum coherences that use only data obtainable in experimentally realistic scenarios.

Quantum Non-Gaussianity of Multiphonon States of a Single Atom.

Quantum non-Gaussian mechanical states are already required in a range of applications. The discrete building blocks of such states are the energy eigenstates-Fock states. Despite progress in their preparation, the remaining imperfections can still invisibly cause loss of the aspects critical for their applications.

Lumbar Spine and Lower Extremity Overuse Injuries.

Both lower extremities and lower back are common sources of injury for cyclists. For providers to optimize care within this area of sports medicine, they need to understand the most common sources of injury in this population. Cycling presents a unique challenge: treating both the athlete and the complex relationship between rider and bicycle.

Radiofrequency Ablation for Thoracic and Abdominal Chronic Pain Syndromes.

Chronic thoracic pain and chronic abdominal pain are common conditions that can significantly affect quality of life. Pain syndromes encompassing a variety of causes, including cancer pain, neuritis, and postsurgical pain, are traditionally managed by the use of pharmacologic therapy; however, many cases are refractory to these conservative methods. Radiofrequency ablation (RFA) has been increasingly used as a tool to treat resistant, chronic pain of both thoracic and abdominal origin.
