Universal Subspaces for Local Unitary Groups of Fermionic Systems
For the representation $ ho$ of the local unitary (LU) group $G$ on the $N$-fermion Hilbert space $\mathcal{V}=\wedge^N V$ with $M$-dimensional single particle space $V$, a universal subspace $\mathca...

Self-testing using only marginal information
Abstract: Self-testing, aka device-independent tomography, refers to the fact that some quantum states and measurements can be uniquely determined from the observed statistics, without any prior char...

Towards an Optical Frequency Standard based on 176Lu+
Abstract: In essence, the accuracy and performance of an atomic clock ultimately depends on various systematic shifts in the narrow-linewidth transition in an isolated atomic system. Lutetium ion pos...

Enhancing quantum sensing sensitivity by a quantum memory
Abstract: In quantum sensing, precision is typically limited by the maximum time interval over which phase can be accumulated. Memories have been used to enhance this time interval beyond the coheren...
