Abstract
We experimentally demonstrated a protocol for measurement device independent entanglement witness (MDI-EW) presented in [1]. A measurement device independent (MDI) protocol will allow two parties (Alice and Bob) to verify that they share an entangled state via the help of trusted input states without making any assumption on the measurement device using only the statistics of the output of the measurement device. Verification of entanglement between states is important as entangled states are a commonly used resource in several aspects of quantum information science such as quantum key distribution. Experimental implementation of MDI-EW in discrete variables have previously been demonstrated in [2,3].
