Quantum Journal Club:Dynamical decoupling of a single-electron spin at room temp
Abstract: Here we report the increase of the coherence time T 2 of a single-electron spin at room temperature by using dynamical decoupling. We show that the Carr-Purcell-Meiboom-Gill (CPMG) pulse se...

Quantum Journal Club: Universal Dynamical Decoupling of a Single Solid-State Spi
Abstract: Controlling the interaction of a single quantum system with its environment is a fundamental challenge in quantum science and technology. We strongly suppressed the coupling of a single spi...

Joint measurability for binary quantum measurements
Abstract: The ability to perform two measurements simultaneously is not granted by quantum mechanics. In this talks, I will introduce several notions, such as joint measurability and coexistence of m...
