Quantum Journal Club: Implementing a Universal Gate Set on a Logical Qubit Encoded in an Oscillator
Abstract: A logical qubit is a two-dimensional subspace of a higher dimensional system, chosen such that it is possible to detect and correct the occurrence of certain errors [1]. Manipulation of the...

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...
