Abstract: Abstract We investigate the dynamics of quantum-memory-assisted entropic uncertainty relations under two typical categories of noise: phase damping channel and amplitude damping channel. It is shown that, the entropic uncertainty monotonically increases and tends to… read more here.

Abstract: We propose a scheme to enhance entanglement from amplitude damping or correlated amplitude damping decoherence. We show that entanglement sudden death time can be prolonged by the initial single-qubit operation combined with local filtering operation.… read more here.
