Drawing from a socioecological framework of health, this community-based participatory research study examined key cultural health perspectives of transitionally housed, food insecure Indigenous children (aged 8–12 years) by utilizing talking circles and a 4-day photovoice (PV) curriculum. In total, 18 Indigenous children portrayed their health perceptions by taking photographs of their living environment and categorizing photos as healthy, unhealthy, or mixed. And, 10 of the 18 children completed pre- and post-evaluations, where data elucidated that urban Indigenous children experiencing food and housing insecurity demonstrate unique holistic and socioecological perceptions about health. Healthy themes included nutrition, gardening, interpersonal relationships, food sovereignty, water quality, and natural and built environments. Unhealthy themes included cumulative stress, food insecurity, access and cost, screen time, smoking, and violence. We found that implementing these robust insights into urban Indigenous obesity prevention interventions could significantly drive success. This approach may benefit children with similar socioecological strengths and vulnerabilities.
We present a couple of protocols based on shortcut to adiabaticity techniques for rapid generation of robust entangled Bell states in a system of two two-state systems. Our protocols rely on the so-called transitionless quantum driving (TQD) algorithm and Lewis-Riesenfeld invariant (LRI) method. Both TQD and LRI methods result in high fidelity in population transfer.Our study shows that it is possible to prepare an entangled state in infinitely short time without losing robustness and efficiency.In the realm of quantum physics, adiabatic passage protocols are most widely and rigorously exploited in last few decades for various applications related to coherent control and quantum information processing [1] [7] etc. One of the advantages of adiabatic passage technique is its robustness towards atomic decoherence on the fidelity. However the main shortcoming in this method is that it follows adiabatic evolution that makes it sufficiently slow with respect to time. The quest to overcome this limitation ends up in a set of new theories that are nowadays known as the shortcut techniques. Among them, two methods gained particular attention recently, namely Transitionless Quantum Driving (TQD) or Counterdiabatic algorithm [8,9] and Lewis-Riesenfeld Invariant (LRI) based approach [10]. TQD permits us to control the time evolution of a particular system exactly along the adiabatic path beyond adiabatic limits by means of additional interactions. On the other hand, LRI based approach follows the invariant dynamics determined by appropriate boundary conditions regardless of adiabatic path and adiabatic conditions. According to these theories, quantum systems can be driven in an infinitely small amount of time without affecting the robustness of the process. Several extensive studies have been carried out in this direction in recent years [11][12][13].Entanglement is another key concept in modern quantum physics. Preparation of different entangled states such as entangled atomic states, entangled states inside cavity and in different optical arrangements [14] has remained a challenge in the context of quantum information and quantum optics. In fact few recent works show that adiabatic following can be implemented successfully for preparation of entangled states. In this context, the work by R. G. Unnayan et al. [15] is of tremendous significance, in which they described the adiabatic evolution from an un-entangled state to an entangled state. They considered a combination of two two-state systems, consists of two spin 1 2 particles coupled by their intrinsic exchange interaction and an external time dependent magnetic field. Such a system, when magnetic field is switched off, can be represented in terms of conventional singlet and triplet states, among which two are basically the entangled Bell states for a bipartite system. With magnetic field being switched on, these four states get coupled to each other. Choosing these four states as basis, one can readily study the adiabatic evolution of this system. This work triggered...
