Quantum Journal Club: Operating Spin Echo in the Quantum Regime for an Atomic-En
Abstract: Spin echo is a powerful technique to extend atomic or nuclear coherence times by overcoming the dephasing due to inhomogeneous broadenings. However, there are disputes about the feasibility...

Quantum Journal Club: Quantum Dynamics with Spatiotemporal Control of Interactio
Abstract: Optical control of atomic interactions in quantum gases is a long-sought goal of cold atom research. Previous experiments have been hindered by rapid decay of the quantum gas and parasitic ...

Jaynes-Cummings-Hubbard model and bosonic-particle system using trapped ions
Abstract: Recent advances in quantum technology enabled us to simulate a certain quantum system with another well-controlled system (quantum simulation or analog quantum computation). Systems of trap...
