Electromotive Force in Electrochemical Modification of Mudstone

Coherence-Driven Topological Transition in Quantum Metamaterials.

We introduce and theoretically demonstrate a quantum metamaterial made of dense ultracold neutral atoms loaded into an inherently defect-free artificial crystal of light, immune to well-known critical challenges inevitable in conventional solid-state platforms. We demonstrate an all-optical control, on ultrafast time scales, over the photonic topological transition of the isofrequency contour f...

Symmetry games in driven quantum dot circuits

Quantum dots are central components of semiconductor based electronic quantum circuits. They are being investigated for their potential for quantum information applications and provide a test bed for studying fundamental questions, for instance as local detector embedded in the matrix of a crystal. Laterally defined nanodevices allow the design of symmetry properties. This opens up new perspect...

Topological characterization of periodically driven quantum systems

Topological properties of physical systems can lead to robust behaviors that are insensitive to microscopic details. Such topologically robust phenomena are not limited to static systems but can also appear in driven quantum systems. In this paper, we show that the Floquet operators of periodically driven systems can be divided into topologically distinct homotopy classes and give a simple phys...

Optimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits

There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....
