Optimal rates for independence testing via permutation tests
Defining a natural measure of dependence $D(f)$ to be the squared $L^2$-distance between a joint density $f$ and the product of its marginals, we first show that there is generally no valid test of in...

Quantum Journal Club: Observation of the Efimovian expansion in scale-invariant Fermi gases
Abstract: 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 the...

Quantum Journal Club: Semi-device-independent bounds on entanglement
Abstract: Detection and quantification of entanglement in quantum resources are two key steps in the implementation of various quantum-information processing tasks. Here, we show that Bell-type inequ...

Quantum Journal Club: Operating Spin Echo in the Quantum Regime for an Atomic-En
Abstract: Spin echo is a powerful technique to extend atomic or nuclear coherence times by overcoming the dephasing due to inhomogeneous broadenings. However, there are disputes about the feasibility...
