Entangling coherent states into a maximally entangled qudits and/or qudit cluster states
内容： Optically coherent states can be interpreted as qudits with arbitrary integer d. Weak cross-Kerr nonlinear interaction can maximally entangle two coherent states and this can be used for variou...

Quantum Journal Club: Observation of the Efimovian expansion in scale-invariant Fermi gases
内容： Scale invariance plays an important role in unitary Fermi gases. Discrete scaling symmetry manifests itself in quantum few-body systems such as the Efimov effect. Here, we report on the theoret...
