Reliable quantum cloning at the Heisenberg limit
Abstract: No process in nature can perfectly copy an arbitrary quantum state. But is it possible to engineer processes that replicate quantum states with vanishingly small error? We devised a probabi...

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...
