Proposition 3.2 requires certain decay properties for the integrand in a complex strip, and thus is not always applicable. As is shown in Appendix A, the transformation maps partly into the left-half plane. One can even show that the real part changes sign infinitely many times when evaluating...
We prove that a finite correlation length, i.e., exponential decay of correlations, implies an area law for the entanglement entropy of quantum states defined on a line. The entropy bound is exponential in the correlation length of the state, thus reproducing as a particular case Hastings’s...
Analysis of multiexponential decay has remained a topic of active research for over 200 years. This attests to the widespread importance of this problem and to the profound difficulties in characterizing the underlying monoexponential decays. Here, we demonstrate the fundamental improvement in stability...
For the same set of data (R = 1), the stretched-exponential model yields a considerably better goodness of fit even for the case of its worst performance: the double-exponential decay (χ2/dof < 3.5). Also here, from a practical point of view, an important conclusion can be drawn ...

8. Quantum kernels are expected to find use in a mix of scientific and practical applications including classifying types of supernovae in cosmology11, probing phase transitions in quantum many-body physics12, and detecting fraud in finance13. Moreover, kernel methods are famously said to enjoy ...
Exponential equations are used to model situations such as population growth, radioactive decay, and compound interest. To solve an exponential equation, we can use logarithms. By takingthe logarithm of both sides of the equation, we can isolate the variable and find its value. For example, ...
