Publisher Copyright: © 2023 by the authors.Bathua (Chenopodium album) is a rich source of extensive-ranging nutrients, including bio-active carbohydrates, flavonoids and phenolics, minerals, and vitamins that translate to countless health benefits such as anticancer, antidiabetic, anti-inflammatory, antimicrobial, and antioxidant activity. Ascaridole, an important phytoconstituent present in aerial parts of the plant, contributes to its anthelmintic property. Even with vast historical use and significant health benefits, its renown has not spread, and utilization has significantly decreased in recent decades. Gradually, the plant has become known under the name of Non-conventional edible plant (NCEP). This compilation is prepared to bring out the plant under the spotlight for further research by foregrounding previous studies on the plant. Scientific research databases, including PubMed, Google Scholar, Scopus, SpringerLink, ScienceDirect, and Wiley Online, were used to fetch data on C. album. This review offers over up-to-date knowledge on nutritious values, phytochemical composition, volatile compounds, as well as health benefits of C. album. The ethnobotanical and ethnomedicinal uses of the plant in India and other parts of the world are deliberately discussed. Scrutinizing the reported literature on C. album reveals its powerful nutrient composition advantageous in the development of food products. The impact of various cooking and processing methods on the nutritional profile and bioavailability are discussed. The future perspectives with regards to the potential for food and nutraceutical products are critically addressed. This review proves the necessity of breakthrough research to investigate the pharmacology and safety of phytochemicals and nutraceutical development studies on the C. album.Peer reviewe
Benchmarking the performance of portfolio optimization with QAOA
We present a detailed study of portfolio optimization using different
versions of the quantum approximate optimization algorithm (QAOA). For a given
list of assets, the portfolio optimization problem is formulated as quadratic
binary optimization constrained on the number of assets contained in the
portfolio. QAOA has been suggested as a possible candidate for solving this
problem (and similar combinatorial optimization problems) more efficiently than
classical computers in the case of a sufficiently large number of assets.
However, the practical implementation of this algorithm requires a careful
consideration of several technical issues, not all of which are discussed in
the present literature. The present article intends to fill this gap and
thereby provide the reader with a useful guide for applying QAOA to the
portfolio optimization problem (and similar problems). In particular, we will
discuss several possible choices of the variational form and of different
classical algorithms for finding the corresponding optimized parameters.
Viewing at the application of QAOA on error-prone NISQ hardware, we also
analyze the influence of statistical sampling errors (due to a finite number of
shots) and gate and readout errors (due to imperfect quantum hardware).
Finally, we define a criterion for distinguishing between "easy" and "hard"
instances of the portfolio optimization problemComment: 28 pages, 8 figure
