    Quantum secret sharing with qudit graph states

    Full text link
    We present a unified formalism for threshold quantum secret sharing using graph states of systems with prime dimension. We construct protocols for three varieties of secret sharing: with classical and quantum secrets shared between parties over both classical and quantum channels.Comment: 13 pages, 12 figures. v2: Corrected to reflect imperfections of (n,n) QQ protocol. Also changed notation from (n,m)(n,m) to (k,n)(k,n), corrected typos, updated references, shortened introduction. v3: Updated acknowledgement

    Are children and adolescents with food allergies at increased risk for psychopathology?

    OBJECTIVE: Living with food allergy is a unique and potentially life-threatening stressor that requires constant vigilance to food-related stimuli, but little is known about whether adolescents with food allergies are at increased risk for psychopathology—concurrently and over time. METHODS: Data came from the prospective-longitudinal Great Smoky Mountains Study. Adolescents (N = 1,420) were recruited from the community, and interviewed up to six times between ages 10 to 16 for the purpose of the present analyses. At each assessment, adolescents and one parent were interviewed using the Child and Adolescent Psychiatric Assessment, resulting in N = 5,165 pairs of interviews. RESULTS: Cross-sectionally, food allergies were associated with more symptoms of separation and generalized anxiety, attention deficit and hyperactivity disorder, and anorexia nervosa. Longitudinally, adolescents with food allergy experienced increases in symptoms of generalized anxiety and depression from one assessment to the next. Food allergies were not, however, associated with a higher likelihood of meeting diagnostic criteria for a psychiatric disorder. CONCLUSION: The unique constellation of adolescents’ increased symptoms of psychopathology in the context of food allergy likely reflects an adaptive increase in vigilance rather than cohesive syndromes of psychopathology. Support and guidance from health care providers is needed to help adolescents with food allergies and their caregivers achieve an optimal balance between necessary vigilance and hypervigilance and unnecessary restriction
