Measurements in two bases are sufficient for certifying high-dimensional entanglement

, 2018
High-dimensional encoding of quantum information provides a promising method of transcending current limitations in quantum communication. One of the central challenges in the pursuit of such an approach is the certification of high-dimensional ...

Psychoacoustic Test to Determine Sound Quality Metric Indicators of Rotorcraft Noise Annoyance [PDF]

Noise certification metrics such as Effective Perceived Noise Level and Sound Exposure Level are used to ensure that helicopters meet regulations, but these metrics may not be good indicators of annoyance since noise complaints against helicopters ...

Optimal randomness certification from one entangled bit

, 2015
By performing local projective measurements on a two-qubit entangled state one can certify in a device-independent way up to one bit of randomness. We show here that general measurements, defined by positive-operator-valued measures, can certify up to ...

Ai-Optimized Dental Imaging: Safer Scans, Informed

International Dental Journal
Aim or purpose: The widespread use of dental imaging (e.g., CBCT, digital X-rays) enhances diagnostic accuracy, yet public misconceptions about radiation risks persist, leading to unnecessary refusal of critical examinations.

Noise measurements for a twin-engine commercial jet aircraft during 3 deg approaches and level flyovers [PDF]

Noise measurements have been made with a twin-engine commercial jet aircraft making 3 deg approaches and level flyovers. The flight-test data showed that, in the standard 3 deg approach configuration with 40 deg flaps, effective perceived noise level ...
