Quantum Journal Club：A universal gate for fixed-frequency qubits via a tunable bus
Abstract: Claude Shannon proved in 1949 that information-theoretic-secure encryption is possible if the encryption key is used only once, is random, and is at least as long as the message itself. Not...

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...
