To account for noise, we relax the definition of similarity using the maximum weighted co-k-plex relaxation method, which allows dissimilarities among graphs up to a predetermined level.

Quantum speed limits are not actually quantum

We then formulate the problem as a novel quadratic unconstrained binary optimization problem that can be solved by a quantum annealer.

The context of our study is molecular similarity where the presence of noise might be due to regular errors in measuring molecular features. We develop a similarity measure and use it to predict the mutagenicity of a molecule.

Our results indicate that the relaxed similarity measure, designed to accommodate the regular errors, yields a higher prediction accuracy than the measure that ignores the noise.

It is designed to work on resizable cloud computing platforms. The algorithm takes as input a witness complex K approximating the given point cloud.

It uses quantum annealing to compute a clique cover of the 1-skeleton of K and then uses this cover to blow up K into a Mayer-Vietoris complex. Finally, it computes the homology of the Mayer-Vietoris complex in parallel.

The novelty here is the use of clique covering which, compared to graph partitioning, substantially reduces the computational load assigned to each slave machine in the computing cluster. We describe two different clique covers and their quantum annealing formulation in the form of quadratic unconstrained binary optimization QUBO.A quantum vacuum thruster (QVT or Q-thruster) is a theoretical system that uses the same principles and equations of motion that a conventional plasma thruster would use, namely magnetohydrodynamics (MHD), to make predictions about the behavior of the propellant.

However, rather than using a conventional plasma as a propellant, a QVT uses the quantum vacuum fluctuations of the zero-point . Research Paper on Quantum Physics May 11, UsefulResearchPapers Research Papers 0 Quantum physics is a general name for a set of the natural theories originated in twentieth century, which, like the theory of relativity, mark a rupture between what is now called classical physics – all theories and physical principles accepted in the nineteenth century.

An interpretation of quantum mechanics is an attempt to explain how the mathematical theory of quantum mechanics corresponds to urbanagricultureinitiative.comgh quantum mechanics has held up to rigorous and extremely precise tests in an extraordinarily broad range of experiments, there exist a number of contending schools of thought over their interpretation.
