Quantum Journal Club: A quantum memory with telecom-wavelength conversion
内容： In a fibre-based quantum information network, telecom-wavelength transmission between quantum memory elements is required to minimize absorption. Owing to the paucity of suitable ground-state a...

Quantum Journal Club: Universal Dynamical Decoupling of a Single Solid-State Spi
内容： 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 spin in...

Quantum Journal Club:Dynamical decoupling of a single-electron spin at room temp
内容： 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 sequen...

Joint measurability for binary quantum measurements
内容： 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 measu...
