Altering the decay of quantum entanglement
Decoherence of phases and dissipation of amplitudes can lead to loss of entanglement between two systems. In particular, an initially set-up entanglement of two qubits can end after a finite time in "sudden death". We show how local, unitary actions by the individual qubits can change this fate. In particular, the sudden death can even be averted all together.
