A logarithmic phase singularity at the heart of Landau-Zener transitions
Eric P. Glasbrenner, David Fabian, Wolfgang P. Schleich
Three ingredients of the elementary Landau-Zener problem determine the familiar expression for the asymptotic value of the probability ampl…
Elementary asymptotic approach to the Landau-Zener problem
Eric P. Glasbrenner, Wolfgang P. Schleich
We present an asymptotic approach towards the standard Landau-Zener problem based on two linearly independent elementary waves of constant amplitude but time-dependent phase. The t…
Time-reversal Interferometry Using Cat States with Scalable Entangling Resources
Sebastián C. Carrasco, Michael H. Goerz, Zeyang Li +4
We propose a novel method for generating Schrödinger-cat states -- defined as equal superpositions of arbitrary coherent states -- using a concise sequence of rapid twist-and-turn…
Advanced Quantum Communication and Quantum Networks -- From basic research to future applications
Björn Kubala, Alexander Sauer, Alessandro Tarantola +7
Classical communication is the basis for many of our current and future technologies, such as mobile phones, video conferences, autonomous vehicles and particularly the internet. I…
Observation of quantum free fall and the consistency with the equivalence principle
Or Dobkowski, Barak Trok, Peter Skakunenko +9
The unification of quantum theory and the general theory of relativity - describing gravity, is one of the most important challenges in science. Einstein's general theory of relati…
Hidden facts in Landau-Zener transitions revealed by the Riccati Equation
Eric P. Glasbrenner, Yannik Gerdes, Sándor Varró +1
We express the dynamics of the two probability amplitudes in the elementary Landau-Zener problem in terms of the solution of the corresponding Riccati differential equation and ide…
