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...

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...

Quantum Journal Club: Microwave quantum logic gates for trapped ions
内容： 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 motio...

Entanglement in Fermionic Quantum Theory
内容： We review the framework of operational probabilistic theories, with particular emphasis on those notions that are related to the structure of composite systems. We then introduce the fermion al...

Foundations of Quantum Field Theory in the light of Quantum Information: The Dir
内容： The experience in Quantum Information has led the community to look at foundations of Quantum Theory under a completely new angle, regarding the theory as a “theory of information”, and leadi...
