Machine learning transfer efficiencies for noisy quantum walks

Melnikov, Alexey A.; Fedichkin, Leonid E.; Lee, Ray-Kuang; Alodjants, Alexander

2020 Quantum Physics

doi:10.1002/qute.201900115

Abstract: Quantum effects are known to provide an advantage in particle transfer across networks. In order to achieve this advantage, requirements on both a graph type and a quantum system coherence must be found. Here we show that the process of finding these requirements can be automated by...

Theoretical methods for ultrastrong light-matter interactions

Boité, Alexandre Le

2020 Quantum Physics

doi:10.1002/qute.201900140

Abstract: This article reviews theoretical methods developed in the last decade to understand cavity quantum electrodynamics in the ultrastrong-coupling regime, where the strength of the light-matter interaction becomes comparable to the photon frequency. Along with profound modifications of...

Simulating artificial one-dimensional physics with ultra-cold fermionic atoms: three exemplary themes

Dobrzyniecki, Jacek; Sowiński, Tomasz

2020 Quantum Physics

doi:10.1002/qute.202000010

Abstract: For over twenty years, ultra-cold atomic systems have formed an almost perfect arena for simulating different quantum many-body phenomena and exposing their non-obvious and very often counterintuitive features. Thanks to extremely precise controllability of different parameters they are...

Bounding the Classical Capacity of Multilevel Damping Quantum Channels

Macchiavello, Chiara; Sacchi, Massimiliano F.; Sacchi, Tito

2020 Quantum Physics

doi:10.1002/qute.202000013

Abstract: A recent method to certify the classical capacity of quantum communication channels is applied for general damping channels in finite dimension. The method compares the mutual information obtained by coding on the computational and a Fourier basis, which can be obtained by just two...
