Amplifying asymmetry with correlated catalysts
Feng Ding, Xueyuan Hu, Heng Fan
We investigate the basic constraint on amplifying the asymmetry in quantum states with correlated catalysts. Here a correlated catalyst is a finite-dimensional auxiliary, which exa…

Masking Quantum Information on Hyperdisks
Feng Ding, Xueyuan Hu
Masking information is a protocol that encodes quantum information into a bipartite entangled state while the information is completely unknown to local systems. This paper explici…
