Enhancing entanglement, local and non-local information of accelerated two-qubit and two-qutrit systems via weak-reverse measurements

摘要

Weak-reverse measurements (WRM) are employed to recover and protect the entanglement losses of entangled two-qubit and two-qutrit systems that accelerate. It is shown that the upper bounds of entanglement for a partially entangled two-qutrit state are higher than that for a partially entangled two-qubit state. The possibility of protecting local information encoded in partially entangled states using the WRM measurements is much better than that encoded in maximum entangled states. It is shown that the possibility of protecting the local encoded information on an accelerated 2-qutrit state, using the WRM is higher than that for a 2-qubit state. Copyright (C) EPLA, 2016
