Photonic quantum technologies

The first quantum technology, which harnesses uniquely quantum mechanical effects for its core operation, has arrived in the form of commercially available quantum key distribution systems that achieve enhanced security by encoding information in photons such that information gained by an eavesdropper can be detected. Anticipated future quantum technologies include large-scale secure networks, enhanced measurement and lithography, and quantum information processors, promising exponentially greater computation power for particular tasks. Photonics is destined for a central role in such technologies owing to the need for high-speed transmission and the outstanding low-noise properties of photons. These technologies may use single photons or quantum states of bright laser beams, or both, and will undoubtably apply and drive state-of-the-art developments in photonics

Associations of Parent–Child Anxious and Depressive Symptoms When a Caregiver Has a History of Depression

We examined the associations between parent and child anxious and depressive symptoms controlling for co-occurring symptoms in both. One hundred and four families participated, including 131 9–15 year old children considered at risk for anxiety and/or depression due to a history of depression in a parent. Parents and children completed questionnaires assessing depressive and anxious symptoms. Linear Mixed Models analyses controlling for the alternate parent and child symptoms indicated that both parent and child depressive symptoms and parent and child anxious symptoms were positively associated. Parental depressive symptoms were not positively associated with child anxious symptoms, and parental anxious symptoms were not positively associated with child depressive symptoms. The findings provide evidence for positive specific links between parent and child development of same-syndrome, but not cross-syndrome, symptoms when a caregiver has a history of depression

The relation between co-rumination, maternal depressive symptoms and child psychopathology

Item does not contain fulltextLittle is known about which processes explain the well-established link between maternal and child symptomatology. Interpersonal coping processes may be worth exploring, as depressed mothers have characteristic coping styles that may influence interactions with their children. We examined two interpersonal coping processes as potential factors explaining how depressive symptomatology in mothers impacts child psychopathology: parent-child co-rumination (dwelling on negative affect, over-analyzing problems) and impaired problem-solving. We analyzed 198 aggressive children (most of whom also had elevated internalizing symptoms) who engaged in structured discussions with their mothers. Coders rated the extent to which dyads problem-solved and co-ruminated during discussions, and mothers filled out questionnaires assessing maternal and child symptoms. Path analysis tested whether higher levels of co-rumination and poor problem-solving statistically mediated the relation between depressive symptoms in mothers and child internalizing and externalizing behaviour. Maternal depressive symptomatology was correlated with greater child symptoms, higher rates of co-rumination and poorer problem-solving. Statistical mediation was non-significant. Results support the established link between maternal depression and child psychopathology, and suggest that dysphoric mothers and their children engage in maladaptive coping interactions.11 p
