A diagrammatic approach to variational quantum ansatz construction

Variational quantum eigensolvers (VQEs) are a promising class of quantum algorithms for preparing approximate ground states in near-term quantum devices.Minimizing the error in such an approximation requires designing ansatzes using physical considerations that target the studied system.One such consideration is size-extensivity, meaning that Dog-S

Numerical and experimental investigation of production performance of in-situ conversion of shale oil by air injection

In-situ conversion of oil shale process has been appealing from economic and energy security perspectives.Conventional in-situ upgrading techniques use electric heaters to heat oil shale, not shale oil.However, the efficiency of electrical heating method is very slow which requires preheating more than a year.Most conventional heating technologies

Critical Care Database Comprising Patients With Infection

Patients treated in the intensive care unit (ICU) are closely monitored and receive intensive treatment.Such aggressive monitoring and treatment will generate high-granularity data from both electronic healthcare records and nursing charts.These data not only provide infrastructure for daily clinical practice but also can help to inform clinical st
