Variational method for learning Quantum Channels via Stinespring Dilation on neutral atom systems

The state |ψ(t)⟩ of a closed quantum system evolves under the Schrödinger equation, where the reversible evolution of the state is described by the action of a unitary operator U(t) on the initial state |ψ0⟩, i.e.\ |ψ(t)⟩=U(t)|ψ0⟩. However, realistic quantum systems interact with their environment, resulting in non-reversible evolutions, described by Lindblad equations. The solution of these equations give rise to quantum channels Φt that describe the evolution of density matrices according to ρ(t)=Φt(ρ0), which often results in decoherence and dephasing of the state. For many quantum experiments, the time until which measurements can be done might be limited, e.g. by experimental instability or technological constraints. However, further evolution of the state may be of interest. For instance, to determine the source of the decoherence and dephasing, or to identify the steady state of the evolution. In this work, we introduce a method to approximate a given target quantum channel by means of variationally approximating equivalent unitaries on an extended system, invoking the Stinespring dilation theorem. We report on an experimentally feasible method to extrapolate the quantum channel on discrete time steps using only data on the first time steps. Our approach heavily relies on the ability to spatially transport entangled qubits, which is unique to the neutral atom quantum computing architecture. Furthermore, the method shows promising predictive power for various non-trivial quantum channels. Lastly, a quantitative analysis is performed between gate-based and pulse-based variational quantum algorithms

Factors influencing decision to breastfeed

Background. The low prevalence and short duration of breastfeeding in international studies have highlighted the need for more investigations into the problems. International studies have identified certain factors that affect breastfeeding intentions. Due to insufficient published studies on the local breastfeeding situation, this study specifically investigated factors influencing the breastfeeding decision among primipara women in Hong Kong. Aim. The aim of this paper is to report a study investigating the personal, social, cultural, facilities and environmental and other factors contributing to women's decisions to breastfeed, and to exploring first-time mothers' knowledge of breastfeeding and its influence on their breastfeeding intentions. Methods. Three private and 10 public hospitals in Hong Kong participated in the study. Both quantitative and qualitative data were collected through questionnaires and subsequently by in-depth interviews with 230 first-time mothers 24-48 hours after delivery. Results. The results indicated that personal, cultural, social, and environmental factors are common influencing factors in the decision to breastfeed. Mother's knowledge and attitudes, followed by husband's support, were identified as important in influencing infant feeding choice. Expected local cultural differences were also identified. Discussion. Acknowledgement of the influencing factors could lead to appropriate management of the promotion of breastfeeding. Further research into husband's role, recognition and support for infant feeding and the issue of 'inadequate breast milk' is necessary for a successful breastfeeding campaign. Some other interesting findings typical of the local culture, such as family communication and living environment relating to breastfeeding, are also discussed. Conclusions. The study has identified the influencing factors that affect women's decision to breastfeed. Recommendations are made for health care professionals and the community to create a more baby-friendly atmosphere and environment for the promotion of breastfeeding.School of Nursin
