Quantum Journal Club: A quantum memory with telecom-wavelength conversion
Abstract: 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-sta...

Quantum Journal Club: Generation and detection of atomic spin entanglement in optical lattices
Abstract: Ultracold atoms in optical lattices hold promise for the creation of entangled states for quantum technologies. Here we report on the generation, manipulation and detection of atomic spin e...

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: Spectral compression of single photons
Abstract: Photons are critical to quantum technologies because they can be used for virtually all quantum information tasks, for example, in quantum metrology1, as the information carrier in photonic...

Tensor network simulation in strongly correlated systems: past, present and future
Abstract: Tensor network states are new kinds of variational wavefunctions that help us to understand quantum phases and phase transitions beyond Landau paradigm. In this talk, I will first review th...

Reachability analysis of quantum Markov chains and quantum Markov decision proce
Abstract: We introduce the notion of quantum Markov decision process (qMDP) as a semantic model of nondeterministic and concurrent quantum programs. It is shown by examples that qMDPs can be used in ...
