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...

Sub-Doppler forces for 137 Ba ions
内容： In this talk I present a theoretical study of calculating sub-Doppler forces for 137 Ba ions. The D1 transition line is employed for cooling line. Two cooling schemes are used: (i) Fg=1 - Fe=2 ...

Quantum Journal Club: Efficient Experimental Estimation of Fidelity of Linear Op
内容： 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 conjugate...

Reachability Analysis of Quantum Markov Chains
内容： This paper studies verification of quantum systems, including quantum programs. We consider three kinds of long-term behaviour, namely reachability, repeated reachability and persistence, of qu...

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...
