RateMechanismThe gas phase OH hydrogen abstraction reaction from leucine has been studied using Density Functional Theory (B3LYP) calculations and the 6-311G(d,p) basis set. The structures of the different stationary points are discussed. Reaction profiles are modeled including the formation of pre...

Quantum computers exploit principles of quantum mechanics, such as superposition and entanglement, to represent data and perform operations on them (Ding & Chong,2020). Both of these principles enable quantum computers to solve very specific, complex problems significantly faster than standard computers....
guaranteed by the laws of quantum mechanics. The implementation of a quantum random number generator based on the von Neumann projection requires: (1) the ability to implement this projection in practice on a specific system, (2) the ability to prepare the system for projection in the same kno...

Neutrino oscillations at the highest energies and longest baselines can be used to study the structure of spacetime and test the fundamental principles of quantum mechanics. If the metric of spacetime has a quantum mechanical description, its fluctuations at the Planck scale are expected to introduce...

We will see later that wave functions in a reasonable setting cannot have compact support: in relativistic quantum theory, this is the case if the energy of a wave function is bounded from below, and in non-relativistic quantum mechanics, an initially compactly supported wave function will instan...
The principles of quantum mechanics, which as far as we know govern all natural phenomena, were discovered in 1925. For 99 years we have built on that achievement to reach a comprehensive understanding of much of the physical world, from molecules to materials to elementary particles and much ...
Level C2 lies in the gray zone and while it may be considered secure for practical purposes, i.e., adequate for a commercial product, one should remember that it has no theoretical security proof based on quantum mechanics. However, the development of security proofs taking into account ...
