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...

Quantum Journal Club: Measurement-Device-Independent Quantum Key Distribution
Abstract: How to remove detector side channel attacks has been a notoriously hard problem in quantum cryptography. Here, we propose a simple solution to this problem—measurement-device-independent q...

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...

Quantum Journal Club: Efficient Experimental Estimation of Fidelity of Linear Op
Abstract: We propose an efficiently measurable lower bound on quantum process fidelity of N-qubit controlled-Z gates. This bound is determined by average output state fidelities for N partially conju...

Quantum Journal Club: Microwave quantum logic gates for trapped ions
Abstract: Control over physical systems at the quantum level is important in fields as diverse as metrology, information processing, simulation and chemistry. For trapped atomic ions, the quantized m...
