We introduce an optimisation method for variational quantum algorithms and experimentally demonstrate a 100-fold improvement in efficiency compared to naive implementations. The effectiveness of our approach is shown by obtaining multi-dimensional energy surfaces small molecules spin model. Our solves related problems parallel exploiting the global nature Bayesian sharing information between di...

In this article, we study the problem of information sharing among rational self-interested agents as a dynamic game asymmetric information. We assume that imperfectly observe Markov chain, and they are called to decide whether will share their noisy observations or not at each time instant. utilize notion conditional mutual information evaluate being shared agents. The challenges arise ...

COVID-19 is a disease caused by novel coronavirus originated in Wuhan, China. The virus rapidly spread over more than 200 countries around the world and deaths of 690.000 people. To prevent rapid spreading this disease, information sharing related to findings about must be fast secure between countries. Since health data such as symptoms private patient records are confidential, requires privac...
