Ensuring the correct functioning of quantum error correction (QEC) circuits is crucial to achieve fault tolerance in realistic quantum processors subjected to noise.The first checkpoint for a fully operational QEC circuit is to create genuine multipartite entanglement (GME) across all subsystems of physical qubits.We introduce a conditional witness
Objective To compare results reporting and the presence of spin in COVID-19 study preprints with their finalised journal publications.Design Cross-sectional study.Setting International medical literature.Participants Preprints and final journal publications of 67 interventional and observational studies of COVID-19 treatment or prevention from the
Transmission error (TE) and backlash are important parameters used to evaluate the transmission accuracy of cycloid-pin drives.Existing calculation methods are mostly based on two-dimensional tooth profile models, and these methods ignore the influence of some abnormal meshing phenomena caused by profile modifications (PMs), manufacturing errors (M
Link Bearing Debate about the relative merits of native versus exotic flora in the landscape has been occurring in many countries, to the point that one author has suggested native plant enthusiasm has moved from ecological panacea to xenophobia.Much of the key landscape character in Europe is in fact based on non-indigenous flora; for example, the
This study analyses consumer last-mile delivery service choice behaviour by developing a cross-nested logit model (CNL); we then compare the analytical results with three nested logit models (NL).The model parameters are estimated using the AEG DLE0970M 90cm Designer Island Hood – CHROME data from a questionnaire collected from consumers residing
